Total Loss Of Power - Wiring Found Damaged

[xsaraiihdi]

Hi All

 

I have a 2006 Citroen C5 1.6 HDI estate  5 Speed Manual Gearbox which has developed a fault. The symtoms are If I pull away in first gear the engine goes into total shutdown and gives an error depolution fault. The only way to start the car again is to turn of the ignition put the car into nutral and wait 10 seconds the car will then start. I can rev the engine but still get the depolution fault. However i can start the car and pullaway in second gear with no problem but still get the depolution fault error. I have scanned it with my Lexia and have error code 1586 rail pressure, flow meter, egr valve copysensor supply and supply voltage to low. 

 

Live Data

 

Rail Pressure 265 bar on tickover

rising to 400 bar at 1500 rpm

 

Any advise please.

i would start with testing the battrey as thats what it telling you the others are because of the battery voltage being low or dropping to much

Thank You for the reply. The battery has been tested and holds 12volts with the engine running I have 14.6volts accross the battery. I have had a closer look today and it seem to have had the gearbox removed at some point possibly for a new clutch and the engine wiring loom has been badly refitted. So I am going to remove the air filter and related hoses so I can get a better look at it. As I suspect there may be some damage to it i.e broken wire or damage to the insulation allowing a cable to short and loos the 5 volt supply to the rail sensor. Will keep you posted.

Had the loom out today and found some chaffing on the loom that exposed the 5 volt red supply wire and damaged the insulation so cut the wire slide some heat shrink over and resoldered the wire repaired the outer insulation and refitted the loom. Checked with Lexia cleared the fault codes and all seems OK.
