I bought my 1994 740il in 1997 with 42,000 miles. Shortly thereafter the idle was real rough. When I took it in for service I was told I needed a new engine. Apparently the alloy reacted negetively to the gasoline in the U.S. The dealed replaced the engine.
I now have 95,000 miles on the engine and the same problem (rough idle) is back. Only problem is that the dealer is telling me there is nothing they can do. They are telling me that the new block had a 36,000 mile or 3 year warantee. I know there was a recall for this problem but I am wondering if there is any recourse with BMW.
Anyone ever had this problem? I think BMW gave me the same block that was originally installed. Any help or advise is greatly appreciated. Thanks.
