Insuring an unknown mod


Registered User
I've been sold a 2014 A7 by Audi in Decebmer and just found out it has been chipped. Don't know when or by who and Audi say they don't know.

This means my insurance is invalid so I need to declare the modification but have no idea what has been done. Any suggestions please?

Audi have said they will put it on a dyno but without a before and after result I'm not sure what use this will be.

The dyno would help as they'll know what the claimed output of a stock A7 should be. The difference will be good enough for insurers.
