VW Code 19871
19871 Description And Summary : |
|---|
The problem is about bank 1, cam shaft position sensor, discharge opening (g300), interruption / short-circuit to b+ the system depends on oil pressure to switch between cam profiles exhaust bank 3 sensor 1 oxygen sensor signal, voltage too low during deceleration also mil request signal active (check for tcm errors too!) will delay your vw fault. |
