I tend to change insurer almost every year, so can’t remember which one at the time. My last encounter with modifications was c. 2011 with a 2009 A8 when I had to pay for the increased HP following an ECU remap, as it was more than 10%. I asked about other things too, and whilst they said I could change wheels and tyres no issue, as soon as you go for a non-standard tyre size, they classed it as a modification to manufacturer spec and it was notifiable. When I asked about the implications of not notifying, they told me that in the event of a relevant claim, they check for any modifications.
