BMW Electrical Sensors, Switches, & Relays for BMW X Series E71 (2008-2014)

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.

This crankshaft position sensor (CPS) provides the engine computer with engine speed data via the harmonic balancer. It mounts off the engine block and reads the front crank pulley to tell the engine what position the engine internals are in. This sensor is crucial for starting the car as the ECU will not allow the engine to start without this signal.

If your battery cables have become worn or frayed, or the IBS sensor has gone bad, its time for a replacement. BMW use the IBS, or Intelligent Battery Sensor, to determine not only the state of charge but also the batteries health and life expectancy. Using this data the car's charging system can appropriately supply the battery with the correct voltage, no matter the age.

Comes as a single cable with terminal and IBS Sensor pre-installed.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!
