my first tdi
New member
2000 TDI Bettle, power loss and error code P1556 first. Replace wastegate actuator with wrong one and worked ok at first. Then power loss again. Cleaned old wastegate actuator then runs better than new. Then power loss new code P1557. Reset with OB 11 and runs great no mill light. I am puzzled. Ran for 500 miles slow powerloss again P1557 code again. Reset with OB and runs perfect ???????? What is going on any know ? Thanks, Al.
