Carbon clean (emissions).

Post by AudiB5S4 » Thu Apr 10, 2014 6:51 pm

Hi there,i was wondering if someone could help me,my car is a 1999 b5 s4 and it failed the mot a couple of weeks ago the main failure was the emissions now when I had a diagnostic test it threw up a few things,lambda sensor,egt sensor so I have had them replaced,it did not come up with the catylic converters thankfully,so my question is what is the best stuff to clean the system out,(i.e red x) to see if it will help with the test,bearing in mind the car had been stood for 2 years,any help would be much appreciated thanks shane.
