I'm pleased to read this post - I also have a W203 , and don't consider the state of some of the paintwork to be acceptable - the car has been looked after , and is a 53 with FMBSH up till now . Other issues have been the SRS light coming on for apparently no reason though STAR says there is "high resistance" on the ignition circuit of the drivers door airbag .
I made a bit of a protest to MB about it , and a nice lady did progress this for me , however the local Main Dealer in Watford thought they were doing me a favour by offering to re-do the diagnostics test for £108 ! I did not take up their offer , but after due consideration of this , I think I formal written complaint to MB with some photos might be the way forward .
I did get told that unless the car had full history , that I could expect nothing out of MB , and for the life of me I can't see the connection between the sump and the paintwork , but there is always an old jobsworth who likes to put the mockers on things .
Does anyone have the Postal address for MB , or better , the email address for the claims dept ? Many thanks !!
edit- silly me , found the contact details !!!
