Audi won't repair A4 under warranty due to modified ECU - what can I do?

I have an 18 month old Audi A4 2.0 TFSI with 13,000 miles on the clock. Recently the engine lost compression so I took it to a local Audi dealer and they assured me they’d fix it under warranty. A few days later they rang to say it had cracked a piston and it would require a new engine, which again would be covered by warranty.

However, the dealer called again to say they have evidence to show the ECU has been modified and the repairs will not be covered by warranty. As I was not the first keeper of the car I have no proof to show this is not the case. What can I do?

These engines are known to be troublesome. But because a previous owner has had the ECU reprogrammed, Audi does not have to fulfil its warranty. So who did you buy it from and when?

If a dealer and if this was within six months you can claim from the supplying dealer. Law here: www.honestjohn.co.uk/faq/consumer-rights/
