BMW E6X M6 Throttle Actuator - 13627834494

The S85 throttle actuator is a known OEM weak point, and the design has been a problem from day one. In our experience the failure rate of OEM units is 100% — every one fails eventually. When it goes, the engine drops into limp mode with the DSC and EML lights lit on the cluster, throwing:

• 2B15 – Throttle Valve Actuator Bank 1
• 2B16 – Throttle Valve Actuator Bank 2

Our Upgraded OEM+ rebuilt actuator fixes this for good. We replace every internal component with higher-rated parts so the unit outlasts the car — and we back it with an UNLIMITED MILES LIFETIME WARRANTY.

What we do to each unit:

• Gears upgraded to superior materials
• All MOSFETs replaced
• Transistors and capacitors checked; voltage regulators, microprocessor, and serial EPROM tested or replaced

Note: priced each. The S85 uses two actuators (one per bank) — order the quantity you need.

Fits: E6X M5/M6 (S85)

Warranty:

• Unlimited miles lifetime warranty
• Labor warranty up to $200 if a shop has to redo the job

Core charge: A $300 core charge per unit is added at checkout. It is a refundable deposit — send us your old unit and we refund it. See the warranty-replacement listing for the full core and warranty process.
