DIY instructions on pulling gears.

Note on Installation: Be sure to heat the gear to 100ºC when both removing as well as re-installing the gear or you risk damaging it. It is a good idea to use blue Loctite® on the small gear pinion shaft.

Note for BEW Engine Code: Vehicles with a BEW engine code will lose Cruise Control functionality unless this modification is also paired with a tune that accounts for it.

Note: This will fit various other non-U.S. market vehicles (Audi, Skoda, etc.). If you have any questions please contact us.
