put expensive v power fuel in it drive it for 1 hr before taking it back to him and get him to retest it, that should do the trick!

Fit a decent aftermarket exhaust and take the car to a garage that will overlook exhaust emissions!

Yes, it's likely your lambda/o2 sensor is shafted ... was it disturbed when you had the new exhaust fitted?
Our 206CC 2.0 has two ... one pre-cat, one post-cat ... but until I get PP working I can't tell which is screwed .. one is, the code reader I have tells me!
