Mk2 Focus ECU fault
Discussion
My elderly Mum has had an intermittent warning on her 2007 Focus Zetec and bunged it into her local main dealer who wants to take a grand off her for fitting a new unit. I have only got a partial story from her (she's 200 miles from me in Oswestry) but I am suspecting its this problem with the ECU:

If I can get the ECU out somehow and off to these guys, would it slot back in and work without any need for resets/diagnostics ? Seems crazy to incur Ford M/D costs when the car is now only worth a couple of grand tops.

The chances of it being a faulty ecu are very very slim, unless it is a well documented problem
Yes they can go faulty, or faults can be caused....but they are usually very rare.
Why exactly are the immediately blaming the ecu ?
Don't know yet, they were supposed to call me today but didn't.....Yes they can go faulty, or faults can be caused....but they are usually very rare.

I have a 56 reg Mk2 focus, just after getting it, it developed an intermittent fault. Took the garage an age to pin point it (understandably!) - the fault code said something like "error in communication between the ECU and the dashboard".
In the end the dash was removed and posted to a company that re-soldered the dry joint in there somewhere. Touch wood, car has been fine since!
The issue only showed itself when driving downhill over a bumpy road, when it did show up all the gauges dropped to zero, acceleration etc was normal. When the joint re-connected all the gauges bounced back to where they should be, but the car went into limp mode, so lag in acceleration and not much power.
