Any ideas would be really helpful.
 
Coolant temp was 4 degrees when error recorded so looks like it was just after you started the car. Is the battery OK , did it start straight away. Could just be one of those things it may not do this again. You could do a quick check for boost leaks, check all the boost pipes for signs of leakage, look for wet oil patches.
 
Coolant temp was 4 degrees when error recorded so looks like it was just after you started the car. Is the battery OK , did it start straight away. Could just be one of those things it may not do this again. You could do a quick check for boost leaks, check all the boost pipes for signs of leakage, look for wet oil patches.
Started first time. It's been an intermittent fault. Had the light come on twice before but not noticed the loss in power.
