Hi,
Today my A2 went to the garag for her MOT. she passed with flying colours, but failed on the engine emissions.
Idle rate was fine, but the 2500rpm level was around 0.49 instead of the 0.30 allowed.
They took her for a run, and cleaned the throttle body, but this did not make much difference.
They are now wanting to take her a longer run, and if needed change the pre cat lambda probe (Appologies for spelling).
If this does not work, they may try the spark plugs or engine timings, after that its the new catalytic converter.
She is mainly used to go to and from work, but often gets a run on motorways about once a month, or longer runs.
Any suggestions at all?
