2012 A6 C7 headlight and ballast

[Simon813]

Hi,

Im after some help if anyone has been in the same position.

We have a 2012 A6 avant S-Line with the Xenon headlights. The passenger side headlight stopped working so we took it to Halfords (yes, first mistake I know!) and they replaced the bulb but no joy. After that the headlight started to get condensation on the inside so I think they have damaged the seal or something similar.
Anyway, now taken it to the garage and they quoted £1300 for new headlight unit and ballast. Apparently ours is water damaged. The vast majority of the quote is for parts with only about £100 labour so I’m thinking about buying either used or non-OEM parts instead.

So the question is, has anyone on here found themselves in a similar position and bought a non-OEM Headlight unit and ballast? There are loads on EBay but don’t want to get caught out. I’m worried that if I buy second hand then the same could happen again.

Thanks in advance

Simon

P.s. I’ve lodged a complaint with Halfords!

Thanks all. I’ve had to fit a new headlight and control unit as both were water damaged. Halfords originally refused to pay but finally after some pushing they agreed to pay 50% of the bill (which was well into 4 figures). Just goes to show it is worth pushing when you know you are right!
