Hi,

My mini (2010 Mini Clubman 1400) failed its MOT today (at KWIKFIT) and I urgently need to get it fixed by tomorrow am if at all possible.

It failed on headlight adjustment, which I can sort myself but more importantly it failed on CO emissions. Hoping for some simple and cheap advice to resolve without the expense of a new cat. I tried an engine improver after it failed and ran it for 40 mins at high revs up the motorway but it still recorded a fail on CO. Results as follows:-

Fast Idle CO: 0.22/HC: 66/Lambda: 0.993

Second Fast Idle CO: 0.26/HC: 58/Lambda 0.992

Second test after the run was still at CO 0.26

Any suggestions would be greatly appreciated.

Thanks,

Mark
