02 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW preheating control unit, part number 12 21 7 801 201. The number stamped on the part is 12217801201; BMW's catalog files it under the short number 7801201. You will find it on our Electrical shelf, under ALTERNATORMOUNTING PARTS. It supersedes the older number 7788327, so a part carrying that number is the same part.
It fits the E46 sedan, coupe, convertible and touring (330d, 2003–2005), with the M57N engine.
BMW draws it on the Glow Plug Unit (12_1197) diagram. It weighs about 240 g (0.5 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
