Hi guys, wonder if any of you guys can put me on the right track, I'm thinking of buying a 2003(53) AUDI a4 b6 1.9tdi quattro, 6 speed in Moro blue (151,000) with service history up to 98,000,on inspecting the car the bodywork is in very good condition, alloys could do with a refurb, the problem I've got is that the interior is a very worn light grey beige colour cloth and wondered if if possible to strip it out and fit a leather heated version ?, also upon starting the engine I noticed what I understand as the ESP symbol permanently illuminated and I pressed the ESP button but nothing happened and the button seemed dead and didn't seem to do anything, I asked the trader but he was unsure himself and said it could be sensor ?, the car test drove OK but seemed a bit sluggish but perhaps just me, I like the car but don't want to end up with a pile of trouble,just a bit worried when I see warning lights permanently on, sorry for the long thread but I'm a bit of a newbie on here, any help would be gratefully appreciated, cheers, andy
