Hey Guys,
First time on this forum!
I bought an A6 C8 in August 2024, everything seemed well until I noticed a huge puddle behind the drivers seat footwell a few weeks ago.
It appears its the same/similar problem everyone is also experiencing, took it to Audi Manchester a few days ago for a check - £145 an hour! they said they needed another 8-10 hours to remove the seats and carpet to identify the leak!! Decided not to pay the £1400 minimum and took the car home. My issue is exactly the same as Mandeep.
Will be taking it to an independant garage for a diagnosis (cheaper labour rate)
In the meantime drafted a letter to send to Audi head office, I will paste it below in case anyone else needs to use the draft etc
Going off all the posts above i'm sure Audi are aware of the issue, whether they will honour the repair remains to be seen, but not holding my breath.
I will report back once I have had a response from head office.
Dear Audi Customer Services,
I hope this message finds you well. My name is ******* *****, and I am reaching out to formally raise an issue with my Audi A6 C8, which I believe stems from a known design flaw.
I have been experiencing water pooling under the carpet in the rear footwell, specifically behind the driver’s seat. After conducting some research, I discovered that this is a common problem among Audi A6 C8 owners, and Audi has issued a Technical Service Bulletin (TSB) outlining the issue as a design fault. You can view the TSB here:
TSB - Audi A6 C8 Water Leak
Additionally, I came across this thread on the Audi Owners Club, where other owners have reported the same issue:
Discussion Thread - Audi Owners Club
This issue is one that Audi is already aware of, and it has even led to a class action lawsuit against the company, specifically related to the water leaks in the Audi A6 C8. This highlights the extent of the problem and reinforces that it is not an isolated issue, but a design flaw that has affected many owners.
Despite this being a known problem, I recently paid £152 for a diagnostic check at Manchester Audi, yet they were unable to identify the source of the leak. However, based on my online findings, the TSB issued by Audi, and the class action lawsuit, it is clear that this is not an isolated incident and is related to a design issue, rather than something I have caused or neglected.
I am aware that Audi has previously honoured this issue and, on occasion, has fixed the problem free of charge for affected customers. Given that this is a design flaw and not an error on my part, I kindly request that Audi UK address the issue in a similar manner, as a goodwill gesture.
I trust that Audi UK will stand by the quality of its vehicles and rectify this issue without further delay. I would appreciate a swift resolution and look forward to your prompt response.
Thank you for your attention to this matter.
I hope this letter helps someone who may need it.
