Do you have a VAG-COM? If so, look at blocks 015 and 016 to see which cylinders are misfiring...
There are quite a few 2.7T engines out there (mine included, dr_bob1, 2001_SilverS4, SilverB...to name a few) that have this annoying misfire problem. I've spent quite a bit of time trying to troubleshoot it (though I could be trying harder). I've had the dealer replace the following: MAF, plugs, coilpacks, injectors, and cylinder head. They decarbonized the system too. Nothing has worked.
I mostly get a cylinder 5 misfire but the others occcasionally register too. Adjusting the idle speed helps a little but, in my opinion, just masks the underlying problem.
I'm guessing that it's something simple that's causing the problem but I just can't find it.

I have an old beta version. I'm not sure it will let me look
at that. I will try it out. If not, I will upgrade to the newer version. I've been meaning to do that anyway....
Thanks.
Thanks.
