Hi, I have a 2005.5 A4 Avant 2.0 w manual, I park it on 20 degree incline, started to notice in the morning the start to be a little sluggish, the car starts but takes couple of seconds, later in a day-no problem even on incline, took it to dealer told me no faults stored in computer, recomended to switch to Shell 93 octane, I always use a brand name 93 octane though. Any ideas? Thanks

 

next time turn your key on, but don’t start car for 5-10 sec. before you actually start the car. let the fuel pump work a little before you start it.

 

ya the fuel may have slid backl towards the gas tank since its a pretty step incline, put key in and waitor let car roll to less incline then start. See if that helps
