Service bulletin A571624 2042941-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The vehicle was delivered with two remote keys that have different exterior finishes. One key has a glossy piano black finish with matte chrome detail, and the other key has a completely matte black finish. Starting model year 2016 TT vehicles and with model year 2017 Q7 and A4 vehicles, vehicles equipped with Audi advanced key (Kessy) will be delivered with two remote keys that have different exterior finishes. Delivering vehicles with two keys that have different finishes is done deliberately. The key with glossy black finish indicates that the vehicle is equipped with Audi advanced key. Vehicles without Audi advanced key are delivered with two matte black finish keys.
