BMW Electrical Sensors, Switches, & Relays for BMW E30 M3 S14 2.3L

Clear BMW chassis

Please ensure your correct model is selected

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. And there's nothing more frustrating than a new part that fails right out of the box. So it's important to choose quality replacement parts over a cheap but faulty piece.

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.
When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This relay is used for the SMG system on the E46 M3 and various applications including secondary air systems on other BMW's. If you find that your SMG-equipped E46 M3 is not starting, this is one of the first places to check as it controls power to the hydraulic unit (the car will not start without hydraulics). Buy one to fix the issue and buy a second so you're not stranded in the future!

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.

The carbon contacts can be replaced on their own but requires desoldering the old ones from the base and then soldering the new ones on. It may be easier to just replace the unit as a whole.

This is the OEM voltage regulator, made by Bosch or Hella. It's the one with the white base and fits most Bosch alternators from 1977-1995 (Valeo and other alternators look very different and have a black cover and base). This part number replaces the previous BMW part numbers - 12311271664, 12321279548, 12311722755, 12321711399 and Bosch part numbers 1197311021 and 1197311028.

Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.

The G30 lithium battery from Braille is designed for the Import Tuner market (4 and 6 cylinder) for track use and has enough power for small black V8 race cars and hot rods with light electrical demands/accessories and standard compression. The G30 comes in the popular ETX 30 Group size, just like the B3121 AGM, so it is small and light enough to mount in a variety of locations. Incorporated in this battery is the same technology used in their race winning batteries used by nearly every OEM developer in classes ranging from SCCA to Formula 1.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. BMW's original C101 bracket which connects to the firewall and holds the diagnosis port unfortunately over time becomes heat soaked and brittle. The OEM bracket, which is no longer available, also features a flawed hinge design that easily wears and breaks. Race German has devised a solution to this issue and developed a new bracket! This heavy duty C101 firewall bracket is completely plug and play. These brackets are CAD designed and feature a two piece design with stainless steel hardware.

Offered by OEM Schaeffler, this bearing replaces BMW part number 12311739203, which is found in numerous BMW alternators manufactured prior to 1996. This bearing helps to stabilize the shaft of the alternator, allowing it to spin freely. If you are experiencing a loud squeaking or grinding noise from your alternator, there is a good chance one of the internal bearings has failed and needs to be replaced.

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.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This item fits the following BMWs:
1988-1991 E30 BMW M3
6/1987-1989 E24 BMW 635csi
