I have a few questions, I have the trifecta on my 01 X5 3.0 along with a exhaust camshaft position sensor that appeared about the same time. I've been reading the post about the wheel sensors and the abs module being the main faulty parts. If I replace my module with one from the link provided above, I need to have the X recoded, correct? If I purchase the BMW scanner 1.4 can I code it myself?
