Number one what fuel cleaner did they use and how did they attempt to clean it?

If they used "Redex" and just ran it thru the engine for a few mins they need shooting.

Go to halfords and buy a product called "Slick 50" its about £15.99 but it works, Pop in a full bottle of that when your fuel light comes on, then fill your tank then take it for a run up the motorway, stretch your gears then take it for another emissions test, if it fail then id be check O2 sensors or poss your cat?

i couldnt tell you what they used or how they done it, im at sea just now so giving orders vis email.... they did say it could also be lanbda sensor or cat or mabey wiring?????   The mrs did have a shot of the car and she said she smelt fuel so would that point to the cat perhaps?

if it smells of petrol then chances are its running rich, sort out this problem and it will hopefully sort out the emissions problem.

iirc redex isnt that good for mk4 golfs? so i would try to avoid using that.
