Clicking Noise From 328i Engine
Greetings to all. I had my 328i (56,000 mileage) into my local BMW dealer yesterday (Friday) for an oil change and basic service. However, when I picked the car up, it had a distinct clicking noise from the engine which I had never heard before. I have now read up on the issue and it sounds like it probably is coming from the hydraulic lifters, a problem well chronicled here and elsewhere. My question is, what could the dealer repair shop have done to cause this? One advisor brusquely told that me that he had seen this problem 100's of times and that it had to be just a total coincidence that it first appeared on the same day my car was serviced. I got the General Manager to intercede and he gave me a loaner car and promised to have the car looked at on Monday.
In case they come back with the "miraculous coincidence" argument, does anyone have thoughts on what they could have done to bring on this clicking problem? Maybe improper oil used?
Thanks very much.
