Apologies for the non-Caterham topic but I had an odd experience the other day in my 2009 Mondeo 2.0 TDCi and wonder if anyone can shed light on it:
Travelling down to Wiltshire and having been driving for an hour and a half, the main road was blocked by an accident and I was re-routed along several narrow country roads, one of which took me through a ford. Prior to going through it I stopped to check that I'd get through it and judged it to be OK. I drove through in 1st gear carefully and got out the other side. After about 100 yards a message appeared on the dash telling me there was an "Engine Malfunction" but not telling me to stop. Thinking water had got in somewhere I reasoned that the engine was still running and it would be OK to continue. The car had put itself into Limp Home Mode and was gutless but was otherwise OK. After about 2 miles I stopped and checked that there was no water in the oil (all fine). When I restarted the car it initially went as normal until the malfunction message appeared again and it went into limp home mode again. Another 4 miles or so later I stopped again and had my lunch. After 30 minutes I started the car again and it was completely back to normal. No messages and running normally. It then did 250 miles without a glitch and has been fine ever since.
I'm intrigued to find out what had happened and can only assume that the exhaust had been cooled down by the water to such an extent that the message from one of the sensors to the ECU confused it. Anyone got any other ideas?
