Ted: in my '94 530i, there was a little bit of a rough idle before replacement. But what prompted the dealer to do the full set of tests was a non-start condition I had (only once). I had replaced the battery and somehow managed to "flood" the engine. With low compression, it wouldn't start. Here is how I "flooded" the engine. When it was cold, I started the car, and shut it off immediately after starting (only 1-2 seconds of running time). I just wanted to make sure the new battery would crank the car before I buttoned up the rear seat. Then, when I went to start the car for real, it just cranked, no start, and I got towed to the dealer. The dealer told me this was a common symptom of the bad engines. He told me that if the "flooding" happened again (while he was waiting for my new engine to arrive), that I should pull the fuel pump fuse and crank it until it started , then put the fuse back in. So, you may want to try starting it when cold, then shutting it off immediatley and see if it restarts OK. If it has problems, pull the fuel pump fuse, start it and hurry down to your dealer. I know this may not be scientific, but it is what happened to me. Hope it helps.

94 530iA, 70K
: I have a 1994 530ia, with 67,000 miles on it and the original Nikasil block. My 6 year/100,000 mile extended engine warranty will expire in 8/99, since my date in service is listed as 8/93. For those of you who have had the short block replacement, I was wondering what the symptoms of your "bad" engine were before the replacement. I know that the most commmon one is rough idling. Mine idles somewhat rough only when it is cold. However, my oil seems to get dirty fairly quickly (it is filthy looking 1500 miles after an oil/filter change), compared with my other vehicles (Volvo 240 and Toyota truck). To me, this indicates possible excessive compression ring blow-by, although the engine does not burn any oil. As I am planning to take my car in this summer for the free leakdown test (before the warranty runs out), any comments on symptoms would be appreciated. This should also serve as a wakeup call to all 1993 and 1994 V8 owners - check with your dealer as to your car's date-in-service, as the extended warranty is good for only 6 years or 100,000 miles, whichever comes first!!
