Details
For those speaking german, here’s a link to the original scanner output text file.
That fault code refers to the fuel tank evaporative control system, which includes the carbon canister, plumbing for condensing fuel vapors, the purge solenoid valve, and the leak detection unit [DMTL] which pressurizes the fuel tank and evaporative system to monitor system leaks. The DMTL is mounted directly to the activated carbon canister, which is located underneath the vehicle.
I have found those solutions:
- Replace leak diagnostic pump (Bosch) BavAuto.com part # 0 261 222 018
- New blue gas cap for safe measure # 16 11 6 756 772.
