Spluttering problem?

[CupraMuscle]

When the car comes on full boost about 3.5k it has started spluttering. This happens in 3rd and 4th gear mainly. Could it be plugs or a coil pack gone? I don't have vag com so can't check that way. Any help would be much appreciated.

Thanks,
Marc.

Any warning lights? Try and find someone with VAG COM in the area if possible as it's pure guesswork without it

could be maf? if coil pack has gone it will sound like a scooby and smell like eggs. Try unplugging MAF and see if it stops, if it does replace MAF.

OK cool, will try that.

Thanks.

thats the way mine went during coil pack failure, never happened at low revs tho, seemed to be more noticable when the car heated up and ya give it a bit...
