Volkswagen Dealer Failed to Fix My Golf Water Leak

I noticed water entering the cabin of my 2017 Volkswagen Golf 1.6 TDI Comfortline on the front passenger side, through the metal area between the dashboard and the A-pillar. I recorded a video showing exactly where the water was coming in. On April 8, 2026, I took my car to the Doğuş Oto Kartal authorized service center. I explained the problem in detail, pointed out the water entry point, and showed the service representative my video. My car stayed at the shop for about 10 days. At the end of the process, I was told the water was not coming in from the spot I had identified but from the front right door seal, and that it traveled from there. I trusted the authorized service center’s technical assessment and accepted this explanation. The door seal was replaced, and various parts were removed and reinstalled. I paid $414 for this work. About seven months later, the same water leak came back. On October 23, 2026, I returned to the same service center. This time, after an inspection and a water test, work order ie57145 stated that during the checks, water was seen coming in between the front right dashboard and the pillar. In other words, the water entry point I clearly showed and documented with my video on my first visit was confirmed in writing by the same authorized service center on my second visit. This time, they said the front cowl panel would need to be removed to fix the problem and proposed another paid repair. I declined, because I had reported the same spot on my first visit and the earlier work did not solve the problem. My objection is not only that my car is leaking again. My main objection is why the water entry point I clearly showed on my first visit was not found, and why I am facing the same problem after paying $414. The second service finding alone does not conclusively prove that the first service was faulty, but taken together, the two work orders and my original video call for a serious technical review. I have submitted formal complaints to Volkswagen Türkiye and Volkswagen AG in Germany. What I expect is a review of the first service diagnosis and the work performed. If the first service is found to be incomplete or faulty, I expect the water leak to be fixed without any additional charge, and I expect my legal rights to be considered, including a refund of the $414 I paid. As a consumer who handed over my car relying on an authorized service center, I do not want to be forced to pay a second time for the same problem.
