I was there twice.

I was there twice.
The first time, thanks to ADAC, I was able to specify exactly what needs to be repaired.
Mercedes did not see itself before in the state of the fault (ignition lock) clearly recognizable

The bill was then about 400 more expensive than the cost estimate.
But was then reduced to demand for the amount to still nearly 1000 euros.

The second time I was there because of the leased line. For error checking.
The error was not found. Maybe a cable is off. But you could not see that.
Computer diagnosis without findings. This brought me then the already existing knowledge that the heater does not work and this information costs 188 euros + VAT.

I can only advise anyone not to go there!
