As above, can it be done?
The ones fitted to my 2009 A3 are aftermarket and I assume the reverse light wire to function and two of the sensors have failed so would it just be better to replace the lot and go OEM?
Not worried about the price (within reason) but is it a big task to complete? Are parts hard to find? I would prefer to use eBay as my first source.
I have read Retrofit Rear Parking Sensors? and it seems to cover anything but has anything from 2009/10 changed since that was wrote?
The car is a March 2009 facelift sportback Sport model.
