BMW cylinder bore wear - peterramsay
Its a bit of an old chestnut now but having just bought a 2 year old BMW 520i SE I am concerned that I may have a Pre Steel lining one. It was registered in Dec 98 with an M52 Engine. The Data plate gives a manufacturing date of Nov 98.It has covered 52000 miles and drives like a dream.(previous owner known to us). The Auto Box would seem to be sealed for life with no provision for oil changes. Would it be prudent to get a dealer or specialist to change it.

From the lits I have from BMW this M52 very probably does have the Nickasil lined bores. But it's worth checkign with your BMW dealer. You won't get a new engine, however, unless the existing one develops a problem fairly soon.
