Mondeo 2002 (March) TDCi 130 (about 61,000 miles).

For about a year now, every so often the car wouldn't start and the glow plug warning light flashes. Turn the ignition off, back on, and hey presto! It starts. It has always started first turn normally.

But the other day the light started flashing whilst i was driving and power was noticeably down. So i think it went into 'limp home mode'? Got home but when i went to start it the next day, it wouldn't. Even trying the usual 'switch-off & back-on' didn't work.

I have read the articles on EGR valves & Camshaft/Crankshaft sensors. Will the fault codes tell me what it is?

1) Is there a way to start it to get it to a garage?
2) How do i get the fault codes out?
3) How do i reset the ECU to clear it?

Can anyone help?
