Sounds like a substandard dealer to me. Mine offers to wash my car even if they only do an oil change or even fix a tire. I think they knew they dinged your door and figured you wouldn't notice if it was dirty. If you complained later you there is no proof. I know dealers that did much worse than that.
Two things to take away from your experience: If you leave yourcar with a dealer for ANYTHING, make sure you and the service writer go over the entire car to check for any damage before and after the car is taken away from you.
Personally, I wait until there is a repeat of a fault before taking it to a dealer. My MKV was "recalled" for a bad Mechatronics unit. I never had it replaced because it only acted up twice in 6 years. Since it had a 10-year warranty there was no hurry.
Anyone who pays $40K for a car but refuses to invest $200 for a diagnostic program is not an enthusiast in my book.
