Got a good bit of work done on the 207 today after an excellent parkrun in the sunshine
It was not warm here as despite the sun the wind was bitter
Anyway, had the engine ECU and engine bay fusebox out and hoped to strip nthe fusebox but sadly it's pretty much a sealed unit. I tried to open it up but it is not easy or advised I believe...
I had all the fuses out and disconnected all connectors and all was lovely and shiny.
I broke all the body earth connections and the main one looked a bit corroded and a bit suspect where it bonds to the body from the battery.. I cleaned them all up and greased them...
Reassembled and despite not running since well before Christmas the engine fired up instantly and ran like a clock...
I put the Lexia (Pug Planet) on it and let it idle whilst scanning all the ECUs. The only ECU to have issues was the engine ECU which moaned about mixture regulation and the downstream oxygen sensor. It always has and has always needed these faults clearing in the past just before any MOT.
Those faults cleared and live data showed both oxygen sensors to be working happily...
The engine cut out once when I was poking around with the Lexia but I'm not sure if that was as a result of the fault or just prolonged idling after not running for so long. It instantly restarted..
Everything is woring properly now, even the central locking from the plip which had failed last time so just maybe...
Next steps is to get an MOT on it and put it on the road for a few months (give Gabriel a rest
and then see how it goes. If the car runs faultlessly I may offer it for sale...
If not, back to the drawing board...
She's an old-school diesel and supposed to sound like that on idle and when cold... Warm and under way she's a paragon of quiet smoothness 
That shell is just far too good to largely scrap and perfect as a basis for a 'new' V6 Activa
