Location: birmingham		All you need to do to check the cts is working is put a volt meter on the pins of the sensor with it plug in. With it running when cold the voltage will be high and as the engine warms up the voltage should start to drop if working correctly

Location: Glasgow/Argyll		Already done this but I'm going to double check this week and make sure the values are good. Checked against technical data that a mate got a hold of last and they were good.

Location: Thinking of vvc'ing my Roadster Brabus :-)		Just looked on my Rave, the coolant temp defaults to 60deg, and the ambient air to 30deg.
so your 59deg is close enough the 60deg imo,
its a bit drastic, but I would try another loom and ecu.

Location: Glasgow/Argyll		Thanks very much for checking that for me.

Yeah looks like it could be a loom swap with associated ECU

Thanks again mate!

Location: wigan		My neighbours car had this very same problem from cold it was a pig to start but ok when warm.
He had the car into tuning places etc and spent ££££££££s on it but still no success.
I was looking at the car for him and asked him to start it up but still nothing . Then i put my finger under the air intake where it goes into the throttle body and noticed a small hole i put my finger over tho hole and result.
Worth double checking i think.
The hole was only a pin size hole.

Location: Glasgow/Argyll		Just seen this, I changed inlets with another throttle body and it made no difference. Car has since been rolled in spectacular fashion so is due a re-shell and will be converted to mems3 hopefully.

Im 99% sure the loom is at fault somewhere but its finding it that was proving a hassle.
