Hi,
Could you perhaps get a friendly MOT test garage to give you a readout on exhaust from each tail pipe for comparison ??

This then begs the question, does the MOT exhaust emmissions check expect a reading from both cylinder banks on "V" engined cars with twin exhaust systems, or come to that, any car with a split exhaust system.

Would think not as my A6 V6 failed on the emmissions on the left pipe but passed when tester shoved it up the other nostril!! Having said that they wern't that strict in all honesty so not sure on the Official line on emmisions

MOT testers are supposed to take a reading from each exhaust and average them IIRC.
