BMW E32 Electrical Sensors, Switches, & Relays

BMW E32 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.

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. This can be very hazardous if the oil level were to fall below a certain amount and went undetected. Oil starvation could lead to oil pump failure and extra wear, tear, and heat in the moving components, leading to engine seizure and complete failure. To ensure your engine is well looked after, we recommend this OEM Hella Level Indicator. OEM replacement for BMW part # 12611704468 and 12611747119.

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.

Voltage Regulator (Bosch Alternator) - 12311747920 - E34,E36,E36 M3 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. There is a wear mark on the contacts and if the tip is within 3mm of this wear mark the 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.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their exacting assembly process and high level of durability you can expect a long service life from all Bosch products.

This is the OEM Bosch voltage regulator and will only fit Bosch alternators.
