Car Forum / BMW Cars / January 2006E39 bore wear problem.
I was looking through What Car price guide today and I noticed it warned of serious bore wear problems in late 1990 cars. Surely this problem was with early 1990 cars. Is this a mistake? pete  SignatureDue to privacy considerations, I will not respond to mail from gmail.com.

I did not know about the M52 problem lasting that late though. pete SignatureDue to privacy considerations, I will not respond to mail from gmail.com.

There is NO problem with the M5x series engines in the US.. until they got it sorted out - the M5x engines still came with a cast iron block, and then with steel inserts in the aluminum blocks. Apparently the Euro cars weren't as lucky. > Really depends on where you are located.

No 'problems' except that the E39 was designed for an aluminium block engine and the cast iron one didn't handle as well. > Apparently the Euro cars weren't as lucky. Euro cars run on Euro fuel - ie that from the Euro suppliers didn't suffer. Those run on fuel refined abroad and imported and sold at 'cheap' outlets may have done.

Surely this > problem was with early 1990 cars. Is this a mistake? I'd guess they're meaning the Nikasil problem. Do a search on this for chapter and verse - but in the UK I'd ignore it. The fuel responsible hasn't been around for many a year, and any damage caused by it would have shown up long ago. Signature*Why is 'abbreviation' such a long word?

Yes I knew about the Nikasil problem and I thought that was all cleared up before the '96 models. The What Car mag says "Late '90s cars plagued by engine wear problems......" It doesn't say this in last year issue and I thought they must be referring to the Nikasil problem. My car is ok but I am now looking for a 540 Tourer so I want to be certain of what problems lay ahead of me. It seems none that I didn't know of previous to reading the magazine;-) pete SignatureDue to privacy considerations, I will not respond to mail from gmail.com.
