BMW Electrical Sensors, Switches, & Relays for BMW F80 M3 S55 3.0L

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.

With 5 preset modes from valet mode to track mode, there are no limits to what you can do.

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.

This is a replacement Manifold Absolute Pressure sensor Located on the charge air cooler. The MAP controls the amount of fuel that goes through the injectors based on the pressure of air at the intake manifold. If your vehicle is giving you a MAP code, replace it immediately to ensure you get the best gas mileage and performance. It is common for this part to fail slowly and cause poor fuel mileage and hampered performance. When it fails, the vehicle will stutter and stall as it falls into a limp mode. One way to check if your MAP is bad is to unplug the connector before starting your car. If it idles well (compared to a previous poor idle), your MAP sensor likely needs to be replaced. If you let this maintenance part go, your fuel economy will suffer as too much fuel is going into the engine and not being burned. A great way to give your vehicle an efficiency boost.
