Hello,
It's only been two months since I got my 03 A4 B6 1.8t qt a/t and so far, I've got a leak from what looks like coolant leak from where the firewall is..dealer's shop says so at least. Now the ESP warning light always lights up. Owner's manual claims the car does this automatically for safety reasons or simply that ESP or ABS could be faulty. When I drive the car for about 20 miles in the morning or if drive it hard; like pushing it to get into the freeway, ESP indicator lights up. After turning off the engine, the light shuts off, I start the engine again and it goes back to normal. This happens almost daily now. Could this be that ESP or ABS is faulty? And then lately, the cruise control doesn't switch on. I have to set the lever on OFF mode for a bit then I turn it on after 10 miles or so it's OK.. Weird stuff. Anyone else experience something similar??

 

Have someone with a real vagcom pull the codes from the ECU and post them back here.
