Hi there - newbie here to the forums.
Picked up a hex-v2 VCDS scanner in an attempt to diagnose my son's 2009 A4 2.0T quattro.
We've had a recurring issue with a p2404 problem, and finally punted to the dealer to fix. The dealer was convinced it was the wiring for the leak detection pump (corroded) and the leak detection pump itself.
Dealer repaired the wiring and replaced the LDP. About 3 days later the p2404 came back, this time the dealer diagnosed and replaced the charcoal canister, said it was full of fuel.
About 3 days later, the p2404 came back. When I called to complain, the service manager assured me there were many components that could go wrong in the EVAP system on this car, and they'd be happy to continue to work on it, just more money and time! So here I am.
Unfortunately, after reading the code with my simple reader, I cleared it out and it hasn't come back yet (3 days ago). I got the VCDS in the mail the other day, so had a change to pull a complete auto scan from the car 2 days ago (attached).
This auto-scan doesn't have the issue showing up yet because the EVAP readiness flag hasn't been set in the ECU yet, it seems.
I've been searching the forums to get an idea of what's next to check - seems there is quite a lot of info on different models, but I suspect many of the diagnostic steps are similar.
I ordered a 3-day subscription to erwin, really only needed 1 day (30 minutes would have been fine probably). I also ordered an online manual on CD from Bentley publishing, but it only runs under WindowsXP (needed to fire up a virtual machine for that).
Found this info on the p2404 code:
http://wiki.ross-tech.com/wiki/index.php/18836/P2404/009220
Anything else I need to look at at this point, before I can run another full auto-scan for this problem? Worth testing the N80? It looks like a major PITA to replace this without taking off the intake manifold.
Thank you!
