BMW 335i 535i 135i X6 N54 Wastegate Repair: Bushing Removal Using Slide Hammer
The JB4 Tune Will Never Fix the Pivot Problem Caused By The Wear in the Bushing Arm. This Problem Can Be Fix. Some Say that it Can Be Fixed Permanently, But Im not so sure. We Do Sell a Rebuild Kit for this Problem. The Rebuild kit is Made of 304 Stainless Steel Just like the Original Material. Keep in Mind this was never a materials Problem, it is a design Problem with the long Travel Distance. BMW Does have a Updated Tune to Help Prevent this Problem, but Im not sure if it Permanently Fixes the Issue. I am Just Happy to be able to save people Money from Having to buy New turbos for about 1600$. We have saved Our customers over $500,000, Instead of Having to Replace the Turbos from the Dealership.
