BMW Electrical Sensors, Switches, & Relays for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

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 Meyle replacement camshaft sensor is built to deliver fast, highly accurate data to the ECU, preventing the performance drops, sluggish throttle response, and rough idling caused by worn-out factory electronics.
