yep it failed
couldn't do an emissions test coz it kept overheating on the idle, took it home and found the fan wasn't kicking in, was going to bypass switches and run it direct to an on of switch but whilst I was fumbling about I found a snapped cable, bit of jiggery pockery later and hey presto fan is working as it should again
Its of back in the morning and as long as it passes the emission test all will be good
