Headlight Range Control Level Sensor defective

[MickCheeseman]

Hi All
Recently got this message on the dash of my 2011 S4 B8.
Headlight Range Control Level Sensor defective.
A quick scan pointed to the rear left.
Inspection revealed the little arm attaching to the lower suspension wishbone was snapped.
A quick trip to Audi resulted in this conversation.
"Hello, I need one of these please."
" Sure, that will be £175 + VAT"
WHAT?
I left without the part.
Searched eBay and a new, non-Audi one, £21
It looks like this:

I was concerned the new one may need coding to the car, so I removed the arm and just swapped it with the one on the car. Just needed a hex key and two 10mm spanners. Not a lot of room in there and a bit fiddly, Did it by removing the wheel.
About a 20-minute job and all is now fine.
Hope this helps someone else.

Mick
