In 2021, my car broke down due to the VANOS gear brackets; the bolts had snapped off. The only way I found out what was wrong was by taking the car to multiple places and paying for diagnostic services, but nobody could identify the issue. Eventually, I brought it to BMW, where they were the only ones who diagnosed the problem. However, they quoted me an exorbitant amount to fix it. I felt I had no choice but to take the car home and handle it myself. I discovered that three bolts were broken, and I suspect the other two had fallen into the oil pan. I managed to acquire both parts for the two VANOS gears and installed them myself since dealing with this issue. After reinstalling the gears, I encountered a problem with the valve cover; I wasn’t sure if one of the broken bolts had hit the top of it, but I knew I needed to replace it as well. To get an update on the situation, I took my car to the first BMW dealership in Hartford. There were complications regarding the loaner car, a $200 deposit on my credit card, and coverage under my full insurance. I contacted BMW headquarters to file a complaint, and during that conversation, the BMW manager told me not to come back, to which I agreed. After filing the complaint and discussing the situation with BMW headquarters, I scheduled an appointment at the Waterbury location. When I took my car there yesterday, April 1, 2025, they refused to address the issue because they claimed they could not see the broken bolts. I explained that the bolts had already broken off and that I had previously brought the vehicle to BMW for a diagnosis, which confirmed that the problem involved the gear brackets and the bolts. I also mentioned that the broken bolts had damaged my valve cover, which I had to replace. However, all they did was inspect the car and dismissed the work I had done as if it were performed by them. My car hasnât felt the same since, and Iâve been struggling with this ongoing issue. Damage that already a cured to my car
