Throttle Actuator Warranty Replacement

This listing is for the warranty and core process behind our Upgraded OEM+ throttle actuators (E9X M3 S65, E6X M5/M6 S85, and E60 M5 S85). If you already know which actuator you need, order it from its product page — this page explains how our warranty replacements and core returns work.

Before you file a warranty claim:

Our unit failure rate is under 1% per year, so if you're seeing throttle codes, double- and triple-check first. These cars throw all kinds of unrelated codes — we've seen an exhaust leak trigger throttle-actuator (TA) codes and send a car into limp mode.

The surest test is to swap the unit from one bank to the other and see if the TA code follows:

• Code follows the unit: that's the rare case where the actuator has actually failed.
• Code stays on the same bank: the actuator is fine and something else is the cause.

How the core and warranty process works:

• Check out by paying the core charge. We ship your replacement unit right away.
• Send us the failed unit, and we refund your core charge.
• Every unit carries an unlimited miles lifetime warranty, plus a labor warranty up to $200 if a shop has to redo the job.

Turnaround: 10-15 business days due to high demand. If it's an emergency, contact us and we'll do our best to help.
