Also if it was glowplug related or even fpr related im sure a code would come up on a scan absolutely nothing there.

Car also does this when its fully operating temperature never when it's cold for first 10mins of driving. So don't think it could be glowplug related as it would be doing it when car is cold.

@Ecomatt i have had dpf removed/gutted i started noticing this issue alot more as soon as i removed dpf. 

Haven't changed glowplugs before car is on 107k now. Spoke with mechanic he said glowplugs don't need changing as you only use them for when starting car when cold and thats it and unlike petrol sparkplugs this wouldn't be the issue.

 

Do you not think it could be fuel pressure regulator? As when the fuel pressure drops thats when it has a funny idle if you blip throttle its fine and runs fine when driving and sometimes when you come to a stop on idle its perfect sometimes it's not.

 

I mentioned the glowplugs as mine failed a few months ago and all were replaced. Have you spoken to the mapper who put on your dpf delete map? There might be an issue with the software rather than hardware.

It has the standerd map all he did was delete egr and dpf. Spoke with him already.

If you saw this alot more after the dpf had been removed, I would look again at the map side. Perhaps something was not coded out correctly when the work was originally done. I dont know if anything else would need to be recalibrated given the increase in exhaust speed and fueling to compensate.

Just noticed this on the fuel lines could this be the cause? No hole or rip but seems burnt somehow.

I have got 2015 Golf 7 GTI and I have the same situation with you about the 2nd cylinder misfire at idle. I changed everything spark, injetor, vs. How did you solve your problem? please can you help me?
