I have the following problem. When the speed is reduced between 3 and 2 speeds, an impact occurs. If I brake more aggressively, the impact is not felt at all.
Diagnostics fails the following fault: N443 - pressure control valve 7, 0002 transmission electronics, 12859 P074200 Inverter bypass coupling does not disconnect (00001000 passive / sporadic).
It is a 2012 V6 3.0 TDI model. The oil was changed but the problem remained.

Has anyone had a similar experience?

The error has been present before. When the master changed the oil and the filter, the error did not happen for 50 kilometers and then again. Mileage is 269,000.
