Just a post that could possibly help someone out. Probably has been posted but this is my recent experience with the main dealer
Car failed MOT with what I expected headlights too low, rear level sensor, said they will check if the part is available and then quoted me £320 to fit. Seen that I had a 10 day retest I declined and purchase the part for £30, the bit that snapped was the rubber close to the ball connecting rod. I figured instead of unplugging and possibly having to 'recalibrate, I just removed the broken rod with just the new bit. Surprised as it came out easily. Job done and took me all 1\2hr as I didn't want to break anything
Total cost £30, Audi £320, absolute rip off as you would think they could just resolve the issue as I've done
Lights back to normal instead of a few feet in front (dangerous)
Here is pics of what was replaced instead of the entire unit
Hopefully this could help someone out
