Today I decided to setup ISTA/D -Rheingold to go back and tackle this fault, since I was told and done research that this couldn't be fixed with INPA.
Ive had this error on the dash ever since I got the car, and ignored it, steering alignment is slightly off by 2 hairs as far as I can tell...
I have some BMW E60 parts for sale on ebay, all the part numbers are listed on each auction so you can make sure you get the correct part. If interested in any send me a PM and an offer and we can work something out.
New IVM module
Steering sensor repair kit
