Octavia 1.9TDi MK1 Cutting out

Hi All,

I have had this fault since December during the really cold weather.

My car is the 90hp, AGR engine and has ran without fault for three years.

Symptoms:

Starts first time, every time - but has started cutting out or stuttering when driving and sitting on my drive. The engine dies for a second and the glow plug light flashes twice, recently during heavy rain it cut out three times on one journey home from work (17 miles). You have to turn the ignition off and restart while moving - starts first time.

Parts Replaced / Checked:

Relay's 109 and 103 have been replaced. Wiring around the ECU and relay plate has been inspected, battery and air box removed to check wiring up to the injection pump. ECU plug has been removed and cleaned, ECU has been removed and PCB inspected for dry joints by eye (I was thinking of taking it to work and using the Microscope)

I have the latest VAG-COM report below:
