My 2000 BMW 328i was off the road for 3 years stored in an out-door garage. Recently asked a mechanic to look at it , he said it needed several parts, which I bought. However, he now says it needs an instrument cluster. Don't understand why, since the car was in working order when it was placed in storage! Also found that some of the windows don't work, and there is no horn or ac working. The driver's seat wasn't working and had him check the fuses after which it worked. He currently has the instrument cluster panel and guages disconnected, but the car can still drive. Last night I took the car to get it cleaned and the car shut down. It finally restarted an hour later and was able to make it there. My question is, do I really need to by an instrument cluster, or can it be some problem with the fuses? Also, does this panel also control the AC and the horn? I am alittle suspicious of the mechanic and wondering if he is taking me for a ride because I am a woman. He says the cluster will cost me $2500!
