Right. As title says. I have the Ford Ecoboost, 1.0l 98bhp version. This has a bluefin map on it and it is now around 151bhp (and has been running fine like this for the better part of the last year). Today i put my foot down (after the engine has warmed up, i had been driving about 15 minutes) and 1) i was surprised my traction control didnt come on, not a massive issue but it always tends to be on point and 2) i suddenly got a massive power loss and w warning popped up stating 'Engine malfunction. Service now' along with the usual little service spanner. I then couldn't go about 40mpg - obviously my car decided to go in to limp mode. I then turned my car off at work (about 3 mins later but seemed like forever) and then back on again and the spanner and message had both gone and my car was back up to power again when i quickly took it round the big work car park. My question is, would i be best seeing how it goes and if it does happen again take it back to ford or removing the map and driving as standard for a while and see if it happens again? I am driving up to Cardiff today so a good trek in it... so any answers much appreciated.
