Steering angle sensor (Q4)

Post by finalfa » Thu Oct 17, 2019 7:45 am

Hi. I connected my Marelli tester today to my Q4, and it showed an error code for the steering angle sensor. And indeed, when the steering was straight, the voltage was 4,97v. After a lot of swearing i got the sensor loose, but i am unable to get it to 2,5v. It just jumps between close to 0 and 4,97. Is the sensor broken or what's up? I measured this with the alfa tester.

Thanks for fast answers :roll:

Solved. Faulty steering angle sensor. Tried with another one, and work good. I did manage to break my plastic piece. Luckily, a friend managed to 3D print some new pieces for me, so now i have a couple in stock (In case any mishaps would happen).

3D printing is good for a lot of things!

Great that you got it fixed 8)
