Hmm, ok.

Shouldn't be alternator as you say it would've jump started otherwise.

Did you check the cam position sensor as well as the crank sensor? Can't think where it is on the hdi...although obviously near the cam somewhere lol. And the ECU is pretty close to the gearbox, didn't knock any of the plugs? If you haven't already, I'd take the battery off, unplug the ECU plugs and plug them back 10mins later to make sure the plugs are ok and reset the ECU.

I thought ecu at one point but I could connected the computer to it and get the codes of it. If I disconnect it and reset. Would it remove my map?

Check your connections. Could be some dodgy wiring or a frazzled plug. Cam sensor is right by your master cylinder btw.

Thanks for the can sensor position. Will have a look tomorrow.
