Well it's come to that time of the year and I've just returned from the garage having forked out for an MOT test... failed :aargh4:

CO reading is 0.74% on both the initial test and the retest.

Has anyone else had this problem on a 1600m standard A3 '99?

I've recently had the cat replaced due to the exhaust blowing at the flange.

I'm going to check the usual, filters and the Lambda sensor but thought I'd check in here first to see if it's a common problem.

Thanks
