I've noticed if my car (170 TDI) is left lying over night, or left without being started for a few days, when I turn the ignition for the first time and the car is starting to fire into life I get an audible warning chime and 'ESP Fault - Please Read Owners Manual' displayed on the DIS for a split second. By the the time the engine starts though, the audible warning has stopped and the warning message is gone from the DIS. It literally displays for a split second (barely long enough to read)
For the rest of the day it'll start up first time without any warnings or messages. It literally only happens on the first start up after the car has been left standing for a while (over 12 hours around about)
After reading this thread it seems Audi say it's perfectly normal, others say it's the sign of a failing battery - ESP Fault please see owners manual
Anyone else experience this? I'm tempted to think it's a failing battery - it would explain why it does it when the car has been left standing (maybe the battery is draining over night and running low!?). Either way I don't feel happy with Audi's claim that it's perfectly normal!
Any advice or experiences appreciated, Cheers guys
