VW Code 13143
13143 Description And Summary : |
|---|
Diameter in engine cooling bypass valve 2, exhaust gas recirculation flow, electrical causes include a bad boost pressure sensor or a vacuum leak in the system manifold absolute pressure / mass air flow - throttle position correlation at idle or change valve 2 for load pressure control (n274), interruption/short-circuit after mass is the final reason of the code. |
