I have the strangest problem on my 2006 Audi A6: whenever I fill up my tank with gas the car has a very hard time starting. This has happened 3 times in a row now. I run the tank fairly low - to about 1 quarter tank or a little lower but never to empty…then I fill the tank. When I get in the car to start it, the engine just keeps turning over trying to start but will not start. Then I stop trying, let the ignition rest for a bit, and try to start it about 5 minutes later and it starts just fine on the first try. Any ideas what could be causing this?
One thing that has also started happening around the same time as the problem above is that when I’m idling at a stop light, I notice the car may start to idle rougly and seem like it is about to die out.
Any ideas? I am the first and only owner of this car…I take good care of it and am an easy going driver. But I do drive a lot and have about 200,000 miles on it after 7 years.
