Hi all, I am suffering a repeat problem with my 90k mile 2004 S4, can anyone help?
After a long trip home at the end of the week I stop the car and leave it in the driveway, the next morning I go out to start it and it won't start. I have tried the following but can not find a consistant fix.
1. New battery in key fob ( battery not neaded for mobiliser deactivation)
2. Using 2nd key (also with new battery), seemed to work once.
3. Long journy leaves the tank with 10 miles of fuel in it so I put in 5 litres from a can at home and this seemed to help start it but I cant believe its the problem, unless AUdi in thier wisdom won't allow you to start a vehicle with low fuel? My 200k Passat TDI and A4 Avant never had this issue and I reg run them to zero. this has work twice.
4. Thinking it s a fuel pressure problem I have tried releasing pressure by removing fuel filler cap.
Nothing above seems to be a garunteed fix but it does start eventually after about 30 mins allthough the fuel top up seems to help but I think its purely coincedental.
Has anyone else found this problem, if so what could be causing this. So far its only happpened in my driveway but I work over 200 miles from home and can only imagine what would happen if it occured soemwhere else.
Look forward to anyones thoughts on this?
