Cat and MOT emissions question - 1.8T 190
Just had the main dealer fail my 53 plate A4 because the car was giving the following two faults:
16795 Sec.Air Inj sys
incorrect flow detected
Cat system, bank 1
Efficiency below threshold
However the test sheet says 'Emissions not tested'
They want £950 to stick a new cat on which they say will solve the problem, but my question is why not test the gasses coming out the exhaust anyway? If they were in range would that not pass the MOT??
What do you think - take it elsewhere and get them to MOT it instead?
