In the context of internal investigations of the diesel issue, Audi has discovered irregularities in the engine-management software of V6 diesel engines of Gen2 evo (200 kW). These engines are used in A6 and A7 models of generation C7, which are now being phased out. The Federal Motor Transport Authority in Germany and the vehicle registration authority in Luxembourg have been informed and deliveries of these cars to retailers have been stopped. The irregularities are to be discussed in detail with the registration authorities in the next series of discussions. The monitor at the VW Group has also been informed about this situation.
