Find Parts That Fit Your Vehicle

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. 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.

Located on the intake side of the cylinder head, this sensor relays the position of the camshaft to the computer in order to determine proper ignition timing. When this sensor fails the engine will generally log a fault code and may place the vehicle into "limp" mode. When this happens it is advised to stop driving the vehicle and address the issue immediately as premature wear or long term damage to the engine is possible.

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 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.

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.

This seal plug is installed in the valve cover of N52 engines and is supposed to prevent oil from leaking out. But the rubber plug loosens or becomes dislodged over time and oil does seep out of the valve cover and eventually into the sensor itself (destroying a very expensive sensor). In extreme neglect oil will contaminate the engine wiring harness or even the DME itself. During any valve cover work we recommend checking for oil inside the sensor or around this plug and replace the plug during any valve cover gasket work. It's cheap insurance against an expensive contaminated eccentric shaft sensor.
