I'm not sure exactly which ones were removed in the end as after trying one I still tripped an EML so further deletions were made
 
I'll run a VAG-COm check and save the codes then get them mapped out - spoke to mapper he said no probs :eek:).

As for venting though I cut the plastic tubing off towards the rear of the car by the rear axle. Shouldn't get any smells from it back there...
