2009 Ford Focus TDCi

Car loses power randomly when accelerating. Dashboard stays lit up but I lose all revs and speedometer drops right to zero. Began with just accelerating from low gears but now it happens in 5th gear on motorways when I try to accelerate past somebody, car becomes heavy, jolts and then loses power. Can restart car with ease and it will drive on until it happens again randomly.

Have the computer scanned for any stored codes. That is going to be your only clue here.

Yeah I guess that is all I can do. Its going into the garage tomorrow. I was just fishing for anybody else who may have such issues either regarding sensors causing this or dpf valve blockage issues so I could gauge a price. But really I guess the computer will tell all tomorrow. Thanks

No, the computer won't necessarily tell all but you can hope it at least gives you a hint. It doesn't monitor everything. There are many things that can make a car act that way so you can forget using someone's past experience. That won't likely be your issue.

Ye that is true. Can be anything from dpf to sensor so I guess only time and mechanic expert analysis will help resolve this. Self assessments of car issues online are nearly becoming as bad as self health online diagnosis ha

I don't know why you keep mentioning the DPF. That is one thing that will definitely not cause that. That deals with the EGR valve only.
Intermittent issues like that are hard even when the car is right in front of you. The system has to be able to be tested while the problem is present. Otherwise you are just guessing.

Really? I was just sent down that avenue from talking on another board. Just goes to show how people can mislead you. Thanks for that heads up because I was nearly sold on the fact that it would be an issue regarding the dpf. They will just have to road test it themselves and when it occurs they can hook up and hopefully point in the correct direction ye?

I WAS PONDERING THE IDEA OF THE ENGINE TORQUING HARD (MAYBE WORN MOUNTS) AND THERE BEING A SHORT IN A WIRE THAT ONLY TOUCHES DURING THE TORQUE.

OTHER THAN JUST LOOKING FOR SUCH A POSSIBILITY

ONE MIGHT POINT THE NOSE OF THE CAR IN A SAFE DIRECTION AND HOLD THE BRAKE DOWN HARD, STICK IT IN DRIVE AND GET ON THE GAS A LITTLE TO SIMULATE THE HIGHWAY TORQUE. IF IT HAS THE SAME SYMPTOMS, MAYBE I'M ON TO SOMETHING?

OR MAYBE NOT, JUST SLINGING YOU ANOTHER POSSIBILITY

Got it the problem diagnosed and fixed yesterday. It was a fuel pressure fault. Changed out the fuel filter and car back to 100% performance. Likely cause was previous owner using dodgy diesel which clogged the filter.
