Trouble Ticket Help Requests for DTC P1137
Help Request Posted
2000 Volkswagen Passat GLS 1.8L Poor Idle Quality, Surge, MIL Lamp on VIN: WVWMA23B8Y
P1137: Bank 1 Too Lean. Secondary air injection pump is once again filled with water. VW in my opinion has placed this pump in a bad location. Does anybody have an angle on this one? Relocating it is quite difficult in terms of the plumbing and wiring harness.
