'04 A4 Will Not Start
Have a '04 A4 1.8 T that sometimes will not start. Have had it into the dealer 4 times and they couldn't find anything wrong. Warranty is now expired. Any suggestions???? Throttle position sensor? Oxygen sensor? Fight the dealer? HELP!!!!!!

Re: Ever replaced your fuel filter?
The fuel pump was replaced by the dealer a few months ago. Don't hear any noise from the back of the car. Will replace the fuel filter then check the pressure.

my 03 1.8t will do that sometimes
the other morning it was 25degrees out and it took 8 tries for it to start, the morning before it was 15 out and started first try. Then sometime it does the warm start where I run in the store, come back out and it takes 3 or 4 tries to get it to start. No CEL's yet! It's getting it's firsted CPO checkup on Friday. I'm sure it will be nothing or very expensive, love a dealer stickin me LOL

Your plugs may be partially fouled. Also, if you are using plugs that are two temps
cooler then stock, cold weather will affect starting if plugs are not warmed, (engine running near normal operating temp). Starting up and turning off within a min may foul the plugs in cold weather, (happened to me).
Plus, the iridium plugs were the worst for this.
I tried all types and found the Bosch copper plugs to work the best.

I'm having the same issue on my 3.0, waiting for my Bentley to do some testing and or someont to
post a fix for it. In the meantime, it helps me when I just turn the key and let it lit for a few seconds - then start the car. i can get it to start on the 1st try most of them time like that or at least the 2nd try.
