“WIFE WENT OUTSIDE TO START HER TDI AND AFTER SITTING AND MAKING NO PROGRESS IN WARMING AND SMELLING A LOT OF UN-BURNT DIESEL SHE DECIDED TO SHUT IT OFF. AFTER SHE CAME INSIDE AND TOLD ME IT WAS NOT WARMING UP AND IT SEEMED TO BE RUNNING OUT OF FUEL VERY QUICKLY I WENT OUTSIDE TO CHECK IT OUT. I COULD SEE THAT DIESEL HAD LEAKED ONTO THE GROUND, SO I OPENED THE HOOD AND FUEL WAS DRIPPING FROM THE ENGINE MOUNTED FUEL PUMP. I LEFT IT OVERNIGHT AT THIS POINT TO MAKE SURE NO FIRES WHERE STARTED. THE NEXT MORNING I TOOK IT APART TO FIND OUT WHAT THE SOURCE OF THE LEAK AND AFTER REMOVING THE PUMP, ASSOCIATED ELECTRICAL, AND RUBBER LINES I SAW THE END OF THE PUMP HAD POPPED OUT OF ITS CRIMPED ALUMINUM CASE. THIS WAS ALLOWING DIESEL TO LEAK PAST THE RUNNING ELECTRIC PUMP AND ONTO THE RUNNING ENGINE WHICH AT THE POINT OF TURNING IT OFF HAD COVERED THE ENTIRE SERPENTINE SIDE OF THE ENGINE COMPLETELY IN FUEL.

After the condition progressed, the module became non-communicative and no longer generated fault codes. This is consistent with internal failure preventing communication. The failure affects braking-related safety systems, including ABS and stability control, and creates a potential safety risk, particularly during emergency braking or low-traction conditions. The condition has been confirmed by both a Volkswagen dealership and an independent Volkswagen/Audi specialist. A dealership diagnosis in 2025 once again confirmed that the ABS pump and module had no communication and required full replacement. Independent electrical testing verified that all external wiring, power, and ground inputs…”

The contact was able to pull over to the side of the road. The contact stated that the failure had been recurring while driving. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the ABS module had failed and needed to be replaced. The vehicle was not repaired. The contact stopped driving the vehicle due to safety concerns. The manufacturer was notified of the failure. The failure mileage was approximately 86,000.”
