13 View BMW DiagramSee this part on the official exploded view→ISA screw — a genuine BMW part, number 07 12 9 903 027. The number stamped on the part is 07129903027; BMW's catalog files it under the short number 9903027. You will find it on our Supplies & Hardware shelf, under Group 12. It supersedes the older numbers 7676601, 9903144, 9903621 and 9904071, so a part carrying any of them is the same part.
It fits every E46 body style (316i, 316ti, 318i and 318ti, 2001–2004), with the N42, N45 or N46 engines.
BMW draws it on 46 diagrams, among them Timing and valve train-timing chain (11_3189) and Repair kit, open timing chain, top (11_6604). It weighs about 10 g (under 0.1 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
