I went to the dealership on May 28th, 2017 to update my diesel.
The reception service was very friendly, but unfortunately had no idea and had to ask 3 times to give a final answer.
The whole appointment was totally deconstructive.
The car key was taken wordlessly and the customer's requests were only indirectly addressed.
I expected that the car would be connected to a diagnostic computer before and after the update and that all relevant data would be made available to the customer.
because with this intervention the engine electronics are massively interfered with and the customer should probably be fooled into thinking that this update is a small intervention.
The car was given back without a word and not a word was said about the actual measure.
And on the way home I noticed that the air conditioning had failed after the update, which was definitely still working before the update.
So I called 4 times and 4 times I was referred to the answering machine, although there was enough service staff who could have picked up the receiver.
But the customer is treated like dirt.
After 4 (!) Hours I was called back and asked for.
In the meantime I had been able to repair the damage myself, because the climatronic was being played around and the employee at the other end was very surprised.
For me it was the last VW and this dealership earned a straight 6.
In this regard, I will complain to the management and at VW itself about how customers are treated, because you have to protect other customers from such people.
