As per title, any help with this is really appreciated.
I have a 2006 Focus 1.8TDCi which I've owned since new and it's now just reached 70K Miles.
A few months back the following problem occured:
When driving the car, the "engine systems fault" warning comes on, accompanied by the little red warning lamp. It normally happens when putting the engine under load in 5th gear - i.e trying to overtake but I can also cause the error show up by flooring the accelerator pedal in the lower gears too (not something I'm in the habit of doing - just did it to get the error to show up).
When the warning has come on, there is a noticeable loss of power - if I press the throttle pedal down to accelerate, it just refuses to rev and I have to back off the pedal then re-apply only slight foot pressure to gradually build the speed back up. This works until I have to drive up any incline - I ended up having to slow to 30mph and get on the hard shoulder on the M2 the other night on that long climb from the River Medway - not good!
I've had three different OBDII-readers plugged into the car with the error message up on the dash but there's NO error codes coming up on the fault-code reader .
We're not that well off at the moment so I don't really want to pay Ford loads of money just to plug another machine into it, has anyone on here had the same problem with their Focus 1.8 TDCi? If so, what was the defective part?
I've heard that the throttle pedal potentiometer and throttle body can cause problems. I just really hope it's not the turbo or fuel pump! ££££
Thanks for your time, Jim.
