I purchased a 2008 Focus 1.8 TDCi Titanium (53 Reg) last weekend and its been fine all week. Then this morning, just a few mins after starting the car it got the 'Engine Malfunction' alert on the computer. I'd only just set off, and the car probably hit about 3k revs. I stopped and re-started the engine (by this time the engineer had warmed up) and the alert was no more. I took it to a garage who plugged the computer in and it had no error codes... He's asked me to take it back to him with the alert on the screen (i.e. not turn the car off, just drive straight to the garage).
It's now happened 2 more times today, both just after starting before the engineer could warm up and after it went over 3K revs. The weird part is that when the light is on, the car feels completely normal, it doesn't seem sluggish and the car's turbo still kicks in... Also, once the car is at temperature, you can take take the car unto 5k revs and the alert doesn't get triggered.
I'm thinking I'm going to have to take it back to the dealership I got it from but I live in Doncaster (UK) and I got it from Lincoln (an hours drive away).
The only thing I can find online is that it may be the cam belt sensor thats malfunctioned, other than that I'm completely clueless
Has anybody got any ideas? I've attached a pic of the error in case it helps.
Thank you in advance.
