This bulletin applies to 2012 Audi A6 models. DTC P0727 (engine speed input circuit no signal, sporadic) may be stored in the transmission control module.

At engine start, the engine speed signal arrives to the TCM with delay. The entry is stored because the diagnosis is too sensitive. Drivability is not affected by this condition.

If the entry is sporadic or only sets on engine start, it can be deleted and ignored.
