BMW Throttle Actuator Repair - Worldwide

A common failure with the S85 and S65 engines on BMW's Models: E90 E92 E93 E60 E63 E64 M3 M5 M6

Common symptoms is the car going into limp mode, fault code 2B15 (throttle bank 1) and 2B16 (Throttle bank 2). This can include DSC, and start assistant failure. This is a common problem on BMW cars. We provide a BMW throttle actuator repair, this will solve symptoms with reduced power and start assistant failure for M3 M5 and M6 BMW's. If you read the cars fault code and see 2B15 or 2B16 it is most likely worn gears or a faulty circuit board in the actuators.

The replacement gears we use have a lifetime warranty and they are self lubricating and designed to out live the car. The plastics we use are second to none. Our replacement gears are better than the original equipment fitted in the cars.

Be aware of cheap copies of 3D gears & Brass copies, The brass gear will eat away at other gears quickly and can jam if the engine is hot in summer due to expanding metal. 3D printed copies don't align correctly and don't last! Always replace both sides at the same time.

Electronic Components failure is also common, when you have worn actuator gears, the Mosfets have to work hard, causing them to over heat, this results in the components failing. Its important that buyers are aware that when purchasing the gear kits, its strongly recommended that a full rebuild by us is carried out as kits do not always fix the problem.
