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.

First Check to see if Your Car is Under Warranty with BMW 82,000 Miles and 8 Years. If Your Car is Not under Warranty, you have the Options of Buying New Turbos, Rebuilding them, or Having us Rebuild them for You. Here is Our Wastegate Flapper Repair Kit that You can Buy.

Are BMW N54 535i, 335i, and 135i Turbos the Same? Here is the Difference In the BMW N54 135i, 335i, and 535i Turbos.

The Difference is that the Rear Turbo of the 535i has a Different Wastegate Actuator and Compressor Housing Which i was told is Designed to Clear the Firewall. The X6 Also Has a Difference, the Difference in the X6 N54 Turbos Is that the compressor housing and Wastegate is like the 535i, but the Compressor Housings have Plastic Inlets in Both Compressor Housings, Which Make it Difficult to Upgrade.
