No stat for a model year? Then we very much need more participants for it. Same for those with small sample size notes. Next updates in late August and November.

Do you currently or have you ever had a fuel tank leak that is NOT covered by the recall?

PLEASE PLEASE PLEASE use the following link to report the issue! nhtsa.com

Please include your vehicles year, make, model, trim and vin number! Even if you repaired the problem at your own expense, even if you no longer own the vehicle, even if you don't think it worth your time, PLEASE REPORT IT!

There are alot of models and older years that are not covered by the recalled because of the lack of reports even though they have the same PART with the same DEFECTS! Audi has amended the recall to include more models but there are still so many that have this issue!

Thank you for your time
