I was wondering if anyone can give me some guidance on an issue that I have had with my local dealership. In May of 2006 my clutch went out on my 2002 e46 coupe. Sine I needed to have the clutch replaced I decided to also install a new flywheel. I purchased an aftermarket lightweight flywheel and clutch from UUC MotorWerks. A local BMW dealer installed the parts. I picked the car up from the dealership and noticed a rattle at idle. Since I had done my homework regarding the clutch and flywheel I was not concerned. The dealer noted the rattle on the invoice. The car drove perfectly. Last week I noticed that the car was hesitating when in gear and at speed. I was not sure what the problem was but my first thought was the clutch. I took it to the dealer and they confirmed that I needed a new clutch. I advised them that the clutch had been replaced last year (9000 miles). The dealer promptly indicated that the parts were not BMW and they will not warranty them. I contacted UUC and they advised that they had never had a Clutch/Flywheel fail in this manner, but they have had instances when they were improperly installed and failed as a result. I agreed to send them pictures of the parts when I got the car back.
I picked the car up on a Saturday. I drove it home and all seemed to be okay. The next day I was out running errands and got on the highway. I noticed a slight vibration at 60 mph and between 3000 and 4000 RPM. I did not drive the car on Monday. On Tuesday I followed my wife to the dealer to drop off her car (330I E90) for service. I mentioned my car to the service tech. He indicated that he could not look at my car until Thursday of the following week. I made the appointment and my wife and I left for work. On our way to work in my car, the vibration grew worse and it was followed by a knocking sound. I thought it may have been the guibo. I turned around and took the car back to the dealer. They put me in a loaner and began work on the car. The following day I received a call from the service manager saying that the bearings in my driveshaft were gone. This would be covered under CPO warranty. I began to wonder the following; did I need a new clutch in the first place? If I needed a new clutch could a bad drive shaft have caused the previous clutch to wear sooner that expected? I asked the tech these questions and he responded with the following question “was the car driving when you brought it to us the first time?” I said barely. He then said “was it driving when you picked it up?” I said yes. Then it must have been the clutch.
Any thoughts on any of this? By the way, I do not abuse my clutch or my cars
