Hi, Gents: My 99 A6 Avant has a problem. The engine will not start when I come back from a trip and engine is hot. The engine cranks but wouldn't lit! But can be started after the engine cools down for about 30 min. and have no problem of starting it in the morning. Battery is ok and engine check light is not on! Have not go to dealer yet to check it out, would appreciate any one can give some advice before I go. Many thanks! Bloomsburg |

It is your battery cable. Take a look at it. There is a main wire and there is a second one that feeds the computer. Take the screw out and clean the whole thing with sanding paper or metal brush. It is that simple. Problem gone? I had the sa me thing going and the dealer of course run it through a computer that gave no answer. Later they wanted to replace numerous relays.

the starting problem is more unpredicatable, since you never know when
it will not start! At 1st I thought it was when engine was hot but now
sometimes it won't start even when it been cooled for half an hour.
What's more, the engine check light lits on and off, its not blinking
but stayed on for a day and it might go away in the next day. So I
don't know what is going on now. I think I will let it be that way to
see what will jump out of box.
Oh, when you get a hard start, you can hear the engine cranking hard
and then if you hear the puff noise like you lack of gas, give it a
little throttle, then it starts. Have no idea whats going on!

Bloomsburg If pressing the gas pedal helps it start it might be that adding air is clearing |
Flooding could be caused by leaking injectors. Try a bottle of Techron injector
cleaner in your next tank of gas.
