BMW Electrical Sensors, Switches, & Relays

BMW Electrical Sensors, Switches, & Relays Electrical gremlins can be very frustrating. Luckily your BMW's electrical system is better than most, even if it's 25 years old. Here you will find electrical relays, sensors, switches, and modules for the engine, camshaft, and crankshaft. Our parts are OEM, Genuine BMW, or approved aftermarket brands that we have an excellent track record with. There is no middle ground with electrical parts - it either works perfectly or not.

Genuine BMW Exhaust Camshaft Position Sensor - E46 M3, E39 M5, MZ3, MZ4, Z8 Sensor for: Exhaust. One weak point on BMW engines for years has been the cam position reference sensor. On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VAN0S control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance. Each cam sensor also doubles as a sensor for the VAN0S. So when the sensor goes bad, the VAN0S will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VAN0S. This is the Original BMW sensor with a new o-ring.

This item fits the following BMWs:
2001-2006 E46 BMW M3
1997-2003 E39 BMW M5
2001-2002 Z3 BMW M Roadster M Coupe

Low Fuel Pressure Sensor - E82, E9x, E60, F01, F10, F12 This Genuine BMW low pressure fuel sensor is commonly a cause of a "Increased Emissions" warning on the idrive and for check engine (SES) lights on BMW's with the N54 6 cylinder turbo engine or the S65 V8 engine in the M3. It will also fit a limited number of cars with the N55 engine.

This sensor can be traced to a number of drivability issues, including cold start running problems, misfires, stumbling, hesitations, and overall rough running. You will likely have a code for the misfires, rich condition, or for the sensor itself. In some cases, the combination of codes can bring about a limp mode. Replacing this sensor is an easy and inexpensive first step if you're having any of these issues.

This item fits the following BMWs:

Turner Motorsport Oil Temperature Sensor Flange

The Turner Motorsport Oil Temperature Sensor Flange was designed to get your oil temperature from the best possible location: the sump. Most of the factory and aftermarket sensors are located after the oil pump, which does not give you an accurate temp reading of the oil that is actually lubricating the engine. At the factory temp sensor location the sensor picks up heat not only from the oil stream, but also from the oil pump and housing which will skew the reading. Other aftermarket adapters can be give inaccurate readings from their location and/or design limitations. And may require making unnecessary modifications. By relocating the sensor to the oil sump it reduces clutter and sits flush against the bottom of the oil pan to avoid potential clearance issues. Testing that we have done on and off the track shows that the sump location is the most accurate. We accomplish this by removing the factory oil level sensor or block off plate and using the existing hole and bolt pattern on the oil pan with no additional modifications. Any sensor with an M12 x 1.50mm thread can be used in the flange. 

Note that removing the factory oil level sensor will trigger the low oil fault/warning light. There's no elegant way around this but since the Temp Flange is considered a race-only part we assume you will be checking your own oil level anyway or be using a stand-alone dash/engine management system that does not track oil level. And having the most accurate oil temp is more important.

OEM VDO Camshaft Reference Sensor -- M52/S52

This is a common failure item which can cause a check engine light, and rough engine running on the M52/S52 engines (328, M3, 528 thru 98, Z3 2.8, & M Roadster/Coupe thru 2000). If you have received an engine fault code suggesting "cam shaft reference sensor" or similar, this is most likely the cuprit. Once replaced, you will need to clear the fault code.

Voltage Regulator (Valeo Alternator) - 12311739193 - E30,E36 This is the voltage regulator found on the back of the alternator. It's a normal wear item and the contacts are the first thing to check if you believe the alternator is not charging the battery (lights flickering or dim, battery light on in the dash, the engine quits without warning, or other electrical failures). The voltage regulator manages the voltage flowing through the car, especially to and from the battery. There are two carbon contacts on the regulator that control the magnetic field when the alternator is spinning and these contacts wear over time. A new set of contacts will be about 13mm in length. Anything less than 5mm and the voltage regulator should be replaced, regardless if that is the cause of your electrical problems or not. Most older mechanics will tell you to keep a spare regulator in your toolbox.

This is the OEM Valeo voltage regulator and it only fits to the Valeo alternator (the Bosch voltage regulator is very different).

OEM VDO Mass Air Sensor -- N52 BMW

This is a high quality replacement OEM VDO Mass Air Sensor.The MAF controls the amount of fuel that goes through the injectors based on the volume of air coming through the intake. If your vehicle is giving you a MAF code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAF is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAF needs replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.

OEM Bosch Flywheel Reference Sensor - E23, E24, E28, E30 M3

This is the flywheel reference sensor used on many 1980s BMW models, including E23, E24, E28, and E30 M3. There are usually 2-3 reference sensors mounted on the transmission bellhousing and this one part number is used for both sensors. BMW changed to one sensor part number that covers both of the old numbers (the only difference was the length of the cables). Even though the sensors are the same the ECU is interpreting their data differently. One is used for reading RPM and the other is for crankshaft position or cylinder identification (depending on the model). If the ECU cannot detect crankshaft position or rotation it will not trigger the ignition and start the car. Or if the signal is poor the engine could have misfires, poor running, or hard starting. So this is a vital sensor that you should not neglect! You might even want to keep a spare in your car or toolbox. Priced per sensor.

On the E30 M3 (and possibly others) the old sensors were referenced by markings on the sensor plug. Since the new BMW part number covers both sensors it might be a good idea to mark both ends yourself to help in identification later.

BMW part numbers 12141708619 and 1214708618 are now interchangable with 12141730773.

E30 M3, E24 635CSi TDC Reference Sensor This is a reference sensor used for crank position signal for the E24 635 and a top dead center signal for the E30 M3.

The E24 can have a crank position sensor (CPS) in one of two places: mounted in the transmission bellhousing reading the flywheel (early cars) or on the front of the engine block reading the teeth on the front crank pulley (later cars). The BMW parts information does not show a clear cutoff for each so check your car before ordering. The CPS sends a position signal to the DME so the computer knows when the engine is at TDC and can start the car. It's also when the engine is running for ignition timing. If your engine is not starting or running with misfires this is definitely one of the likely causes. Keep one as a spare to avoid downtime or being stranded!

This also sends a TDC signal in the E30 M3 but it's only used during diagnostic tests. The sensor is located on the upper transmission bellhousing, separate from the other reference sensors. It's only sending a signal to the diagnostic connector, not to the ECU itself. One of the problems with these reference sensors is that they all look alike, especially the male pin connectors on the body of the car. The TDC reference sensor itself is shorter and stubbier than the other two sensors on the M3 bellhousing. Unlike the other two sensors it does not have any markings or special features, just a plain black connector. And it's often missing from the car because it is not required to run and previous owners may have removed it to eliminate confusion.

This item fits the following BMWs:

Relay - Black 7-prong - Fuel Pump Relay This is the fuel pump relay for some E21, E23, E24, E28, and E30 models. The fuel pump relay gets power from the main relay and then powers on the fuel pump. If your fuel pump is not powering on (a buzzing noise is the telltale sign) then the relay may be at fault. It's easy to test with a jumper wire and test light. Note: relays look similar but can perform different functions, and electrical parts are non-returnable, so make sure you confirm this is the relay you need.

According to BMW, this part supercedes these previous BMW relay part numbers: 12621735424, 12631735424, 12631378238, 61311459577 and Bosch part number 0 332 019 456. However, see the note below when replacing a 4 or 5-prong relay)!

Note: this is a 7-prong relay that should only be used to replace a relay with similar wiring. The BMW ETK and RealOEM (and other sites) call for this relay in place of the factory 4 or 5 prong relays but that is not always the case. The 7-prong relay requires an RPM signal to energize the fuel pump and most cars that used a 4 pin relay do not have that signal so the pump will never turn on. If you are replacing a E30 4-pin relay first try the green relay #61368373700. It's more likely the better option (and cheaper).

Please remember that electrical parts are not returnable.

OEM VDO Manifold Absolute Pressure Sensor -- N54 N63 S63 N74

This is a high quality replacement OEM VDO Manifold Absolute Pressure sensor. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP needs replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.

E31, E36, Z3 Crash Alarm Relay This is a new BMW Crash Alarm Relay. In the event of an impact this relay automatically turns on your hazard lights, cuts fuel delivery, and enables the airbags. But they are known to fail just like any other relay and that can cause problems. Telltale signs that this has gone bad is your hazard lights will flash every time you turn the car on (pressing the button will stop them), the hazard lights will turn on while driving, the airbag/SRS light will be on in the dash, the alarm might activate on its own, and possibly other symptoms. If you have any of those issues this could be the culprit. Replacement is easy and the crash alarm relay is located either in the engine compartment with the other relays or under the steering column.

Oil Pressure Switch (fits most BMWs) Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

OEM VDO Valvetronic Eccentric Shaft Sensor - E9x E82 E60 E70 E83 E85 F10 F25

This sensor monitors the position of the Valvetronic eccentric shaft and feeds data back to the ECU. The common issue with this sensor is that it gets contaminated with oil and fails. It doesn't give a fault code or check engine light, however. What you would notice is sluggish driving, hesitation, poor performance, jerky shifts from an automatic, and other drivability issues. These types of issues are typically diagnosed as ignition coils (which are their own issue altogether) but this sensor may also be faulty.

The eccentric shaft sensor is located at the front of the cylinder head and is only accessible with the valve cover off. It's easy to check for oil by removing the engine trim cover (the outer cover with the BMW roundel), unplug the sensor, and look inside. If oil is present inside, or even on the valve cover itself, the sensor is likely contaminated or ready to fail. You can wipe or clean the oil from sitting inside the sensor but it will come back.

If you're planning this job make sure you have our Valve Cover Overhaul Kit, which includes a new seal for the eccentric sensor as well as the rest of the valve cover and Valvetronic gaskets. You can add the valve cover set from the options below.

OEM VDO MAP Sensor -- N20 N26 S55 S63

This is a high quality replacement OEM VDO Manifold Absolute Pressure sensor Located on the charge air cooler. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails completely, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP needs replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.

OEM VDO is one of the largest OE providers in the world, supplying numerous vehicle brands, including BMW, with many of their genuine parts that build the vehicle before they ever reach the car lot. Entrusted by many of the top names in automotives and with their proven history of reliability, it makes all of us here at Turner confident that their line of OEM replacement parts are a perfect option to restore your vehicles original operation and performance.

OEM Hella Oil Level Indicator Switch -- E34 E32 E31 M60 M70 M73 S70

This important sensor detects the oil level in your oil pan. If the sensor dies or has a fault, this can give you inaccurate level readings.

To ensure your engine is well looked after, we recommend this OEM Hella Level Indicator. OEM replacement for BMW part # 12611704468 and 12611747119.

Oxygen Sensor, 520mm (Genuine BMW)

F22 M235, F3X 335/435, F06/F12 640, F10 535, F87 M2 pre-cat Oxygen Sensor (lambda sensor).

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

Genuine BMW Intake Camshaft Sensor - E46 M3, MZ3, Z4 M Sensor for: Intake. A common failure - On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VAN0S control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance.

Each cam sensor also doubles as a sensor for the VAN0S. So when the sensor goes bad, the VAN0S will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VAN0S. This is the Original BMW sensor with a new o-ring.

Applications:
2001-2006 E46 M3, M3 CSL

OEM Bosch Flywheel Reference Sensor (Cyl ID, CPS, RPM) - E23, E24, E28, E30 M3

This is the flywheel reference sensor used on many 1980s BMW models, including E23, E24, E28, and E30 M3. There are usually 2-3 reference sensors mounted on the transmission bellhousing and this one part number is used for both sensors. BMW changed to one sensor part number that covers both of the old numbers (the only difference was the length of the cables). Even though the sensors are the same the ECU is interpreting their data differently. One is used for reading RPM and the other is for crankshaft position or cylinder identification (depending on the model). If the ECU cannot detect crankshaft position or rotation it will not trigger the ignition and start the car. Or if the signal is poor the engine could have misfires and poor running. So this is a vital sensor that you should not neglect! You might even want to keep a spare in your car or toolbox.

On the E30 M3 (and possibly others) the old sensors were referenced by markings on the sensor plug. Since the new BMW part number covers both sensors it might be a good idea to mark both ends yourself to help in identification later.

Main / ECU Relay - White - E30 E36 E39 E38 X5 This is a Genuine BMW main relay for a variety of BMW models. The main relay powers vital systems in the car when the key is turned to the Start position. Things like the ECU and fuel pump require power from the main relay before they can work. The main relay is constantly powered so checking for power is easy with a test light. It should also make a 'click' sound when the ignition switch is turned. Note: relays look similar but can perform different functions, and electrical parts are non-returnable, so make sure you confirm this is the relay you need.

Turner IAT Relocation Harness

If you've ever noticed your car feeling a bit sluggish after a few laps around the track, some hard driving, or even sitting in traffic on a hot day you may have been a victim of power loss due to heat soak.  All vehicles will lose some degree of performance due to heat soak under the right operating conditions.  The engine management system is constantly monitoring operating conditions and modifying parameters based on sensor inputs.  The problem is that BMW integrated the intake air temp sensor in the MAF housing, and often the MAF is sandwiched behind a hot radiator and in some applications next to an even hotter valve cover.  This is fine for overall simplicity and cost of the original engine management system, but less than ideal for optimal performance.  The MAF housing absorbs the excess heat from its surroundings and can’t shed it fast enough, and the ECU reads a falsely high intake air temperature.  It then incorrectly adjusts operating parameters to compensate for the false hot air measurement (pulling timing and running a leaner fuel mixture), and torque output drops like a rock.

The fix?  Locate an intake air temp sensor in a location where it can more accurately measure incoming air temps and where it is less prone to heat soak.  By mounting a sensor further away from the heat source and divorcing it from the mass of the MAF housing, it can both resist the effects of heat soak longer and respond to temperature changes more quickly.  The end result?  You’ll experience reduced loss in torque and more consistent power output when you’re pushing your engine hard. 

The Turner engineering team was initially skeptical of the claimed performance benefits of this modification.  We set out to first validate the functionality and performance benefit of a temp sensor relocation. We set out to replicate stop-and-go traffic heat soak in a 2001 540i in a controlled environment - our dynamometer. Four runs were performed with the dyno's cooling fans turned off to simulate heat soak like being stuck in traffic or low speeds, then the fans were turned on for three more runs to observe the recovery rate once air flow was reintroduced. This was done in stock configuration and then repeated with our sensor relocation kit. 

Result? We recovered 11lb-ft torque at 2500rpm by relocating the temperature sensor! This is a difference that can be felt behind the wheel - owners of M5s can expect an even larger recovery. Here are the heat soak-related torque losses we experienced: 

Stock IAT location Torque loss:
18rwtq at 2500rpm
10rwtq at 3000rpm
9rwtq at 3700rpm

Turner IAT Relocation Torque loss:
7rwtq at 2500rpm
5rwtq at 3000rpm
5rwtq at 3700rpm

Other “kits” on the market require you to cut and splice into your factory wiring harness. The Turner engineering team designed a complete plug and play kit that makes for quick, easy, and reversible installation. Original equipment weather-sealed connectors offer long term reliability, while sheathed wiring offers a clean appearance - you'll quickly forget it's under the hood. We found that different applications called for slightly different sensor positioning and cable routing, so our harness is nearly 3 feet long - long enough to provide flexibility in positioning, but not too long that you're left with unsightly excess wiring. We recommend positioning the sensor in a location away from engine heat, but still within the intake ducting (we found the far side of the airbox base to be a good home). Installation is as simple as drilling a small hole for the sensor and plugging in the harness.

We include everything you need to relocate your IAT - just select your desired sensor brand below (we recommend Beru).

Also the perfect plug-n-play option for anyone looking to upgrade their intake to utilize an Alpha-N tune!
