Hi. Please I need urgent help as this is worrying me now!

I own a 2009 Ford Focus Zetec S 1.8 TDi.

I travelled to Legoland from my home (around 100 mile). Driving down the motorway averaging around 80 mph, at one point I was doing 60 mph and climbing to 70 and the car seemed to lag, like jump, like it was losing power. No dash lights came on so I continued. Nothing else to say.

 

I travelled back from Dorset yesterday, (4 and half hour journey, around 220 miles) and towards the end of the journey, (bare in mind as we were travelling back, I had the odd acceleration jolt and lag), the engine malfunction light came on and power lost. Engine off, back on and fine, still jolts and lags and every time I accelerate as it's lagging it loses power, me back in my seat like a jolt. Like a moving stall. All coolant is fine, oil fine. No lights on my dash apart from engine malfunction but no faults. Its worrying me now as it's happened at least 10 times on different occasions. One time when I had my tire changed, it cut out 5 mins after leaving garage on a roundabout, had it back to same garage and they put it on computer and found no faults. Please help.

May be a bit late now, is this still happening?

There will be a code (DTC) for the engine light, it never just comes on. It is just that the garage may not have looked deep enough. If they are not a Ford dealer, they may have just used a generic OBD2 scanner.

If there are no codes in the pcm (engine computer, which is where an OBD2 scanner looks, then it may be in the instrument cluster, ABS or steering modules. Or communications between them.

You will either have to go to a garage that can access IDS (the Ford system), or get a program like Forscan, which can access all these modules and more.
