2001 Audi Allroad Quattro Question: intermittent starting problems
Hi, This will require someone who has the tools and ability to diagnose this type of problem. Beyond trying to verify the problem, they should check all of the technical service bulletins from Audi, and verify that the vehicle has all the latest software available. They will check for any diagnostic trouble codes stored in every system on the vehicle and then come up with an idea as to what there next steps should be. It may end up being something simple like a vacuum leak, but it could be many other issues, so it really helps to find a shop that can tackle all these other things I mentioned. Good Luck, let us know what you find out! - Bret Bodas
there is an icon in the dash that looks like a car on a key. if this icon was flashing it's an immobilizer (key) issue, if not, it could very well be a fuel pump. keys and vacuum leaks don't usually cause intermittent problems. a fuel pump can be affected by temp changes. this could all be mute if a code is stored for stuff like a speed sensor or something. pull some codes. - some guy
A problem with the torque converter can cause the Check Engine Light to illuminate.
