I've just developed this problem on cylinder 1, and wanted to resurrect this. Any news of whether you guys found out if it's the injectors, lashes, lifters, or intake valves?
clean your intake valves.

Sooo i just developed this problem, i am revo stage II+, 3" exhaust, cai, water meth with 2 injectors, kmd fuel pump upgrade and the sort... i don't know what cylinder but i think its my w/m pooling in the intercooler piping and i think that's it but im not sure...any insight?
Looking through this, it kind of seems like no one really got a resolution to this problem directly. It seems like some things partially fixed it but no full resolution.
Im keen to see a resolution for this as I am have cold start misfires until operating temp is reached. The misfires are from idle to 2500rpm and are only on cylinder 3.
Injector has been replaced, coil packs, new pcv, purge valve, spark plugs, sea foam, inlet gasket. To me it has to be electronic because it stops misfiring at the exact same relative operating temp and rev range.
Must be a resolution out there somewhere!
I think it's the ECM program and fuel enrichment during cold starts, my cyl #4 consistently misses untill temp is normal then the car runs perfect, and yes I've changed everything and cleaned the valves, and nothing changed. this morning all hell broke lose and cyl 234 all missed and gave me code 0456 small evap leak. So I'm starting to lean to a program problem with cold start enrichment in open loop at start.
2010 tiguan misfire on #2 only at idle. replaced the coil and the plugs still there. the damned car has 31000 miles on it. I had a similar issue with my old vr jetta misfires and coil packs and that car was 10 year older you would think they fixed this crap in 10 years. anyway I got a notice that the warranty for the intake manifold has been extended maybe that has something to do with this?
