My wife's 04 1.9TDI Touran failed it's emission test, it has been faultless since owning it from new, in that we've only had the oil changed and the timing belt done a while ago. It has 71k on it. Revo chip and is driven on 3 and 4 mile journeys each day. In and out to the office. No high rev or high speeds.
Is there a known / possible fault that would be causing it's emissions to be too high ?
Is there a set of pipes / manifold etc. that might be getting clogged over the years since 2004, that needs to be taken apart and cleaned out ?
Know a good bit about my ABY and AANs but not his diesel.
Any help is appreciated, it has to go for it's retest in two weeks time, prefer to ask here rather than on a diesel forum I am not familiar with.
Thanks.
