First post, I've searched the forum and do not see this, so i'll try a new one.
I have an '03 A4 3.0 FWD. It was has been cold and we've had an unusual amount of snow over the holidays so I have been driving my Dodge 4X4 and my cars have been parked in the garage. The A4 sat for about 10 days and when I went to start it, it just clicked like a low battery, so I jumped it to start it then charged the battery. It starts fine now(I know look into a new battery) but the warning indicator for the ESP system is on all the time now. I do not have a computer tester and it is a couple of hours to an Audi dealer. Question is do you think this is just a faulty warning due to low voltage, or should I get it to a dealer ASAP? Also, does anyone know how I can reset the light to see if it comes back on?

 

how long have you driven it with the light on? after the battery dies that light will stay on for a while, but mine usually goes off after just a few minutes.

 

Thanksfor the quick reply, and I haven't driven it yet, started snowing again, but I will take it out and see if it clears up.
