Good question! I'll check that later - going to reset the ecu and take it out again. The fan works fine, coolant was at the max level, I've since flushed the whole thing out and refilled with the appropriate mix. It feels to me that it's "strangled" and then runs hot on a longer run as a result. Sigh....

stop, engine overheat" light. This could be related to low coolant or an electric cooling fan problem.I would run the engine up to hot and check if the fan cuts in.Really can't see any connection between power and trip miles.What did the main odometer read?

WELL! What a plonker, top tip here, put your specs on... I thought it said 36 miles, but it was reading an entirely accurate 3.6 miles... doh! Have reset the ECU, had it out for a spin to do the re learning thing, and seems to be OK. Still feels underpowered, but running fine. Maybe I'm just too used to 160BHP...
