Default help? is it a ECU problem ?

Hi their, I have a 2007 Peugeot 207 1.4hdi with around 75,000 miles and 5 days ago I broke down I called out a mechanic and we couldn’t pump any fuel through the fuel filter so we replaced that and he cleared some codes and I was able to drive home. A day ago the same problem happened again and I broke down through no response to throttle however, this time a RAC man come and I tolled him the previous ocation and he simply took the battery off checked a few earth points which were okay but it was dark, reconnected battery and it started! He said that the ecu has a glitch or dpf ? I feel its defiantly a electrical fault but not sure what and today I went to travel back from work and it wouldn’t start, disconnected battery and reconnected after 15 mins and nothing ? what could it be?

Bad earth?
Water damage on ecu or bsi ?
Glitch in the ecu?
Or maybe it needs a software update or hard reset?

What fault codes? If none get a diagnostic check done.
RAC man hasn't s clue, no dpf in your engine.

yeah it was a cut of power to the throttle was unresponsive. (ecu cut fuel to engine) and i got it started today and drove it back home. the code is p1586 and another that links to glow plugs ? both codes are connected to the same point of the ecu so could it be wiring? maybe a update? earth inside the ecu? or is my ecu on its way out?

Id say its the egr causing it. When it doesnt start again disconnect the egr valve. See if it starts then.

ah okay thank you. what dose a egr valve do? And would it stop fuel going to the engine ? and play with the fuel and temperature gauges as they seem to not work when the brakes down ?

also 3-4 weeks before it broke down the first time round, the dash suddenly said that i had 6,542 miles before i needed to fell up ? :s
