    BMW E36 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.
    You're currently viewing parts for your (E36) 3-series 1992-1999. Reset your chassis

    This is the o-ring used for most BMW camshaft sensors and crankshaft sensors. Although most sensors that we sell come with this o-ring at no charge, they may be the source of oil or fluid leaks. Simply replacing the o-ring, rather than replacing the whole sensor, is preferred. Fits with many BMW models and multiple cam, crank, and pulse generator sensors.

    Sold per o-ring.

    This is the coolant temperature sensor used in many BMW models from the mid-1990s to the mid-2000s. The engine computer relies on the coolant temp to set the fuel mapping for the engine. As the car warms up the computer changes the fuel mixture. If your car is running a bit rich (too much fuel) it could be because this sensor is failing and not sending the correct info to the computer.

    This sensor is located in a variety of places depending on the engine. But it's one of those easy replacement items 'while you're in there' when doing a water pump or thermostat replacement.

    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.

    This part replaces the original BMW part number 61351384761 and 61351384732.

    This item fits the following BMWs:
    1992-1999 E36 BMW 318i 318is 318ti 318ic 323is 323ic 325i 325is 325ic 328i 328is 328ic M3

    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. We recommend replacing the cam position sensor o-ring at the same time.

    This sensor is used on 1996-1998 328i, 1996-1999 328is, 1996-1999 M3, 1997-1999 528i, and 1997-1998 Z3 2.8 liter.

    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.

    This Oil Pressure Switch fits the following BMWs:
    1985-1991 E30 318i, 318is, 325e, 325i, M3

    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!! You may also want to pick up the green fuel system relay as a spare too (see below).
