My 9/95-build 530i has the old block.
I suspect 5/95 is about the date that initial efforts were made to fix the problem, maybe that's what's being refered to. I don't think they discovered the true cause until well into '96, however we still want to know what engine Bill has!
It's not impossible to read the numbers with a mirror and flashlight from above, just do it in the dark with a cold engine. Look under the right-rear exhaust ports.
: : I read a post from someone on the UUC Digest last week that in effect said all 540's made after 5/95 had the updated engine block to prevent the sulfur degradation problems we have all learned so much about. I just got off the phone with a BMW NA rep who confirmed that fact. I was flabergasted, to say the least! I had a leakdown test performed on my car at 35,000 miles just to check, and the dealer obviously didn't know this fact either. I have not talked with my dealer about this yet, but intend to. If you wish to call BMW to verify, the number is (800) 831-1117, then press "1", then "4" to get to the customer rep dept. While I am not taking this as 100% gospel, it is helping me to feel better, as my car has 54,000 miles, runs great, and was made in 10-95.
: The best way to identify whether you have the Nikasil block is to read the code off the engine block. I have a '95 530i which came into service 11/95 (not sure of the manufacture date) and it has the "older" engine.
