I have a 2004 325xi m54 engine. e46. I have 3 lights on. The center triangle light in yellow. Then my park light is yellow. My mechanics says its most likely my abs module. 1000-1200 dollars. From what I've read. a bad sensor will trigger a fault code. Plese help. I did a simpl test by hooking up a electric meader on the sesor it self. My front passager sensor doesnt show a signal so I'm assuming this is where the problem lies. I purchase a new sensor on ebay and it was the wrong fit. Why am I not supprised. I believe the correct part number is 34 52 6 756 382. Please I need any possible recommendations.
