2009 Mk7 2.2 115 loss of power and starting issues.

[BobG]

About 12 months ago (18,000 miles) I noticed that my Transit van was struggling when going up hill. I looked under the bonnet/hood and noticed that the air inlet pipe to the air filter was disconnected. I re-attached the hose and that seemed to cure the fault. A few months later the fault reoccurred manifesting itself as reduced power above about 2200 RPM. As I'm a sensible driver this didn't cause immediate concern and by the time I'd decided to take the van to a garage the fault cleared itself. Then about 6 months back the fault came back but at about 2000 RPM. Again the fault cleared as I was about to visit a garage. Then last week I started the van as normal but stalled as I hit a small rock on my unsurfaced driveway. The van took a good 5 seconds of cranking to start it and it would no longer idle when cold. Also it suffered a severe loss of power and hesitation/juddering above 1800 RPM. After driving for,say, 100 miles the van will struggle to restart when hot. It drives sweet as a nut at 1600 RPM but as soon as you put your foot down it's like hitting a rev limiter! Any ideas?

There is no untoward smoking and the battery is a new Bosch unit. Mileage is 117,000 with no major components changed yet.

Get it diagnosed with the Ford IDS program, it could be something quite simple That will have the 2.4 common rail engine which shouldn't show much wear at that mileage but fuel pumps do wear out and often the debris damages the injectors. Typical early warning is the error code for low pressure at cranking.

Had a Navara that did similar things which they never did solve.

DPF filter

Fuel rail sensor

ECU

Could all be culprits.
