Wastegate Repair Kit — BMW N54 Twin Turbo | OEM 11657593015 / 11657593022
Fix Boost Control Faults on Your BMW N54 — Rebuild the Wastegate, Save Thousands.
BMW N54 twin-turbo engines are well known for wastegate rattle and boost control issues — P0234 (overboost) and P0299 (underboost) codes, boost fluctuation, and rattle from the turbos at idle. A full turbocharger replacement on the N54 costs $2,000–$5,000+. In most cases, only the wastegate internal components have worn — this kit rebuilds them precisely.
Why Rebuild the Wastegate
- Eliminates Wastegate Rattle: Worn wastegate internals cause the characteristic N54 turbo rattle at idle — rebuilt wastegate is silent.
- Restores Boost Control: New internal components restore accurate wastegate positioning — fixing boost faults and limp mode.
- Clears P0234/P0299: Proper wastegate operation resolves boost-related fault codes.
- Major Savings: N54 turbocharger replacement costs $2,000–$5,000+. This kit costs $59.
