Mines certainly the misfire I've suffered lots of times before. Sorry for the rushed explanation was a flying toilet break at services onthe way to the airport.

 Strangely it Isn't noticeable after switching back to st2+ ....  Neeeed to find somewhere suitable to do some logs....

What map are you on now?  APR still?  What stage map were you running before you went back to 2+?

Still APR till Xmas. Started missing & stuttering on 2+ map, switched to stock and wasn't noticeable, switched back to 2+ for last 30 - 40 miles and wasn't stuttering.  Was alot less weight in the car on the way back (less load on the engine?)

Hmm maybe it's not the same thing. Mines very intermittent. I wonder if it's the DSG hesitating on a change?
 

....I think a DSG hesitation feels different from a misfire. For a start the DSG hesitation will only happen at the exact moment of your shifting whereas a misfire is usually more throttle related.

I need it to happen again so I can decide. Haven't had any issues with the gearbox so far...

Well it's done it again. This time with a flashing EML, although it stopped flashing when the juddering stopped. I've now noticed it happens mainly when going uphill. Should be able to scan it tomorrow (not VCDS though)

Had mine checked today.  The same happens under load (Uphill or high gears)

Dealer swapped plugs to see if it moved from Cyl  3 but it didnt, then new coilpack and no change.  New Rev PCV next week then looking at injector :sad:

Injector would make sense. It doesn't do it driving gently, but if I accelerate quicker than normal driving is does it a little bit
