Before you order

Is this the same part as the OE number?

It is an aftermarket part engineered to the specification for 8M0057693 / 8M0065239 / 8M0062515. It is not a genuine OE part and we are not affiliated with the manufacturer. The cross-reference tells you what it replaces.

How do I confirm it fits my vehicle?

Match the cross-reference numbers on this page against the number on the part you are removing, or send us your VIN / engine model and we will confirm before dispatch.

What does the warranty cover?

24 months against manufacturing defect — material, workmanship and function. Wear items and damage from incorrect installation are excluded. Claims go to a US address, not overseas.
