Gettings Engineers Reports Done
Can anyone on here recommend a few companies/people to do me engineers reports?
I have an issue with my Focus that Ford are unwilling to call a fault and have freely admitted they can't repair.
It always happens when you've used little to no throttle for a bit and then start to feed in some more throttle.
Sometimes the engine bogs down and feels like someone is applying the brakes before it picks up, sometimes nothing happens for a few seconds before it shoots off (almost feels like turbo lag) and sometimes the engine cuts out quite harshly for a split second before it starts to go. The latter almost feels like you hit something in the road.
The fault is intermittent, most of the time the car drives fine but I hate having anything wrong with my car and this really frustrates me.
The car has been returned to Ford 13 times, the last time it was returned I was advised by the tech at the dealer that there was a few others complaining of the same thing and it is a programming glitch with the EGR valve. As so few people were complaining of it there was nothing they could do and no repair available.
Unfortunately the dealer wouldn't give me the above in writing and Ford Customer Relations won't admit there is a fault with the car.
I have recorded live data of the fault happening.
The graph shows in order of top to bottom...
Throttle Position (%) in RED
Engine Speed (RPM) in GREEN
Road Speed (KPH) in LIGHT BLUE
Fuel Delivery/Flow (L/H) in PINK
Fuel Desired (MM³) in YELLOW
Fuel Rail Pressure (Volts) in BLUE
Inlet Manifold Pressure (kpa) in PINK
Mass Airflow (g/sec) in ORANGE
EGR Position (Volts) in RED
ECU Volts in GREEN.
At 1549.06s (about a third of the way across from the left) you can see on the top red line I have increased my throttle position. At which point the fuel delivery (PINK) and the Fuel Desired (YELLOW) have both nosedived to nearly zero before they start to increase. You can also see where my RPM (GREEN) dropped slightly as a result.
This is the cutting out/bogging down/hesitation I'm feeling.
I'm now 100% sure this is a calibration issue as all the sensors are still reporting perfectly acceptable readings.
And again at 1850.58 and at 1858.88 (half way)...
But yet where I accelerate just before 1880.39 the car pulls absolutely fine with no hesitation what so ever.
I am now pursuing the financial ombudsman to assist me with rejecting the vehicle but I need reports from reputable companies to back up my claims.
Can anyone recommend any companies to do this for me?
I think 3 reports would be reasonable.
I have asked Stu @ Motorsport Developments.
I've also asked a local firm who I use for most of my maintenance who haven't got back to me.

I know ford have pointed out and said its possibly a egr fault (which you can clearly see in the live data the erratic change) but I'm 99% sure you have the dreaded throttle position problem, have you measured the throttle position from 1% to 100% at both ends(pedal and body)
I would have happily helped and put my input on writing but your miles away from me
It's quite bad that ford won't attempt to help being as its not that old

The throttle moves smoothly from 0% to 100%.
Out of curioisty where are you based? I am planning on driving upto M Developments in Blackpool so don't mind a drive.
