Hi all

I own m202 Duf which I believe has had quite an interesting life. Anyway bought her with a full years mot and when I moted her she failed badly on emissions. Took her to renno in Clapham and she been there for 6 weeks
s in total. To be fair to renno he has only charged me 300 quid but we have not found the problem. Initially it was failing on CO HC and lambda. We put a cat on her, put a standard ecu and then checked air filter, injector, lambda sensor, vacuum leaks etc. Renno has got it now that HC and lambda are fine but it is still failing CO. Renno don't know if the piston rings have gone, the engine gives good compression on all cylinders but they think oil could still be getting in the cylinder or its over fuelling possibly double pulsing with the injectors.

Anyway with RS sport in Wimbledon no more I am at a loss where to go next?

are members aware of good Renault or engine specialists near south west london?

thanks
