Finally happy with the repairs on the car although the jury is still out on the Distronic issues until I have more time to road test it as it only happened now and again.
The Good

The Drivers door had a new inner wing trim installed, all ok
They polished out the scratches on the rear window, all ok
Chips on passenger door repaired (whole door re-painted along with the front wing) all ok
The not so good

Indication in bonnet where chip previously was still visible (after being painted)
repair to scuff on passenger side of centre console was carried out using a paint product, unfortunately whoever did it made a lousy job of masking up the surrounding area and proceeded to get over-spray on the console storage flaps/covers as well as the Air Con Control unit !!
Distronic was apparently re-programmed but proved unreliable to trust it after testing it for only a short time
Obviously the above issues were brought to the dealers attention, I suggested that as I was going on Holiday that I drop it back to them to investigate/rectify as required.
This I did and can confirm the following after picking the car up yesterday;
The Bonnet was re-painted again, all ok
Top Section of the Centre Console was replaced with a new unit from a new A250 Demonstrator c/w a new Air Con Control Unit
Distronic re-programmed, more testing required although it seemed ok on the way to work.
All in all i'm finally happy as I said but disapointed I had to return it a second time to get it repaired properly.
