This is a genuine BMW basic control unit DME (exchange unit), part number 12 14 7 526 791. The number stamped on the part is 12147526791; BMW's catalog files it under the short number 7526791. BMW's catalog calls it “EXCH Basic control unit DME”. You will find it on our Electrical shelf, under Other Engine Electrical System parts. It supersedes the older number 7527015, so a part carrying that number is the same part. BMW has since replaced it with 7533652.

It fits the E46 sedan, coupe, convertible and touring (325i and 330i, 2001–2006), with the M54 or M56 engines.

BMW draws it on the Basic control unit DME (12_1213) diagram.

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
