2022 Audi Q8 55 tfsi light bar delaminated

[Nigel SGP]

Noticed my rear light bar has started delaminating in half a dozen places no outside impact damage it’s coming from inside the unit Audi immediately offered to change this under warranty just a heads up to see if yours is ok as they cost around 1600 quid to buy

Cheers mate so am I they didn’t hesitate so nice one Audi the parts on back order couple of weeks should be all good 👍

No probs at all. If the parts on back order it makes me wonder if it's a common fault

Hi Nigel.
Great news! They changed it under warranty.
I have the same issue with my Q8 2018, but it's all the rear lights, and in some cases, with very heavy delamination of the internal lenses.

Audio UK states all these rear units are air-tight and water-tight sealed; it seems they are in denial that they have a manufacturing defect issue. There are now so many issues being reported globally regarding the delamination of the internal light lens of the rear lighting units on different forums.

This is the response I received from Audi UK. I hope your warranty doesn't expire should you experience this issue again!

Many thanks for updating us and I too am please on the under-warranty replacement has worked out well for you. 
Re. the Q8:- what is your washing regime with the vehicle? 
Kind regards,

Hi that looks crazy I’ve been looking around and don’t see any other makes with the problem how can the lights be watertight there is small holes all the way along on the light bar the washing excuse is ridiculous on a prestige car I personally take my cars to the same car wash I’ve used for years 3 Q7’s and 2 S5’s  no problems ever . The  front lights on the Q8 mist from the inside from new its actually in the manual saying this is normal but I think they have problems with the lights which is a shame on a otherwise fine car
