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

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.

Sensor for: Exhaust. One weak point on BMW engines for years has been the cam position reference sensor. On the S54 engine in the E46 M3, M Roadster, and Z4M, there is one sensor for each cam. The sensor tells the computer the position of the cam on cylinder #1. The computer relies on the sensor's information to set injection timing and VAN0S control. When a sensor goes bad, the computer loses track of what position the cam is in. While the engine will continue to run (taking its measurements from the crank position sensor), the entire system is thrown off. The engine may stumble or run rough, but not misfire, and there will be a loss of performance. Each cam sensor also doubles as a sensor for the VAN0S. So when the sensor goes bad, the VAN0S will revert to a safe mode and will not advance.

While the engine will still run with a faulty cam position sensor, it's not running in its finest tune. The DME will have fault codes related to the cam sensor or for the VAN0S. This is the Original BMW sensor with a new o-ring.

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 anti-theft throttle controller from Dahler lets you custom-tune your throttle's responsiveness and the security of your vehicle. With 5 preset modes from valet mode to track mode, there are no limits to what you can do. The anti-theft feature completely disables the throttle when activated, so when if in an unfortunate theft situation, even with the car started and in gear, there is no way your car can move, saving your vehicle from falling into someone else's less-than-legal possession. COMFORT MODE (blue) Unfamiliar terrain and too much traffic? This mode lets you take it easy. Your gas pedal reacts less sensitively – especially when starting off. Your stress level will thank you. ECO MODE (green) $5.00 a gallon? There are a few tricks you can use to save fuel and money when driving. This driving program supports you in reducing the average fuel consumption of your BMW if certain rules of economical driving are observed. SPORT MODE (red) This driving program gives your vehicle a much sportier character. Your BMW reacts with a significantly better response and a straighter acceleration. The response time of the engine is significantly improved. TRACK MODE (purple) If you are not yet satisfied with the sports program and you like to push yourself to the limit, then give it a try. For those who go on tracks or run cars with 85 Ethanol this mode might be the right choice.
