Service bulletin 37 14 23 2028472

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 ignition key cannot be removed even though the gear shifter is in Park (P). The vehicle is mechanically in the Park position, but this is not recognized electronically. The gear shifter cannot be moved from the Park position. On vehicles with Audi advanced key, the vehicle cannot be locked by remote control after the engine has been switched off.The Park position of the gear shifter is sporadically not recognized, which causes the ignition key to not be cleared and prevents the vehicle from being locked.
