Failing to start, plethora of fault codes
#1
Good evening,

I'm in a quandary with my 2013 1.6HDi Berlingo Van at the moment.

It has been driving perfectly, a great little van with no issues up to this point when i dropped it off at the MOT station.

I got a call later in the day as the van was driven into the garage and onto the ramp for the MOT inspection.  

From here on it then failed to start and has done ever since ( it will turn over but not fire ).

The battery was then fully charged and a jump pack was also used to coax it to start but nothing beyond turning over.

Scanning the vehicle ( i don't know the particular scanner at the moment ) the fault codes that came up were;

Engine Management 

P0003  Control of the Fuel Flow Regulator. Short Circuit to Earth
P0245 Turbocharger. Short Circuit to Earth
P0031 Oxygen Sensor Heating. Short Circuit to Earth
P2426 Control of the Bypass of the EGR Exchanger. Short Circuit to Earth

these were the initial fault codes but since then ( 4 days later ) there have been some more;

Engine Management


P0003  Control of the Fuel Flow Regulator. Short Circuit to Earth
P0245 Turbocharger. Short Circuit to Earth
P1445 Addititive Adding.  The quantity of Addititve injected into the FAP has exceeded the Maximum threshold. The FAP must be changed.
P0031 Oxygen Sensor Heating. Short Circuit to Earth
P2426 Control of the Bypass of the EGR Exchanger. Short Circuit to Earth

OBD Codes ($03)

P0003 Fuel Volume regulator " A " Control Circuit Low
P0245 Turbocharger/supercharger Wastegate Actuator "A" Low


I've been using the garage for over a decade and never had any issues with my vehicles in the past with them.  
I'm not concerned about their integrity regarding working on the vehicle but we're at the point that they are very busy and it's difficult to get any time to deal with a issue when i just had time allocated to an MOT.


I'm here to ask for any advice of where i could help point them in a direction to look.

My inexperienced thoughts looking online are the DPF is playing up or full perhaps?  Why this would cause the short circuit to earth i have no idea, perhaps someone could elaborate?

At times when the ignition was switched off, the fans continued to run.  This has happened quite a lot and i have checked coolant levels etc and never found an issue so i put it down to a Citroen quirk ( not having owned one of these before ) but is it possible the van was trying to perform a DPF clean and was interrupted?

The spanner light has been on the dash at start up for about 4k miles now.

I do local short runs but have spent a few months doing a fair bit of motorway driving ( 4-5 hours twice a week ) recently.

Any advice is greatly appreciated

Many thanks

I am having similar issues having the P003 & P0245, I have managed to get the van to run for short periods by resetting the codes within the ecu or disconnecting the battery for a few minutes and reconnecting.  Unfortunately my local garage won’t look at it for at least 2 weeks and other garages in the area won’t even touch it and suggested that I should take it 120 miles to a main dealer.  

I am hoping to do some more digging around and will post if I manage to resolve the fault and will follow your post hoping your garage can find a resolution.

I'd be thinking of some possible issues like water in the ECU, mice chewing wires, blown Masterfuses (hidden under the top tray of fuses in the engine bay fuse box) as these sensors are only connected by their wiring to the ECU and the fuses controlling sensor power circuits.

A soft reset of the BSI wasn't successful, a hard reset will be done today pulling the jumper to see if that will clear any faults.

Looking around a little more, i'm inclined to believe it could be an empty ELOYS tank or blocked DPF as the car was running then spluttered and died on the ramp.

As the codes possibly relate to 2 separate issues ( electrical and mechanical ), i'm hoping a reset and inspection of the BSI may help identify the electrical

Get someone to crank the engine for a minute while you hold your palm tight onto the end of the exhaust, if there is no pressure there then the DPF could be fully blocked. Otherwise it will pop your palm off the pipe straight away (an engine is a pretty powerful compressor) - that pressure would be escaping somewhere else, as it has to come out somewhere or the engine would not even crank fully if the DPF was truly blocked.

You would have gotten warnings about "risk of filter blocking" if it was getting full or there was no Eolys fluid (it isn't measured but estimated based on mileage and fill-ups) so if it's just hit 100k then the warnings would be thick and fast, but it would not have just stopped working because of that - till you'd been plagued by warnings for a while.

All these "short circuit to earth" codes mean there are no signals coming from any of those sensors to the ECU, which points to a common loss of electrical power, i.e. a blown fuse, a dislodged plug, or a cut harness wire.

The BSI plays no part in any of those sensors nor does it get involved in any engine function, except that the immobilizer is contained within it, and it authorizes start when the correct key is used. The ECU asks for key authorization, the BSI says yes, then the engine ECU starts the engine.

Resetting the BSI will not help with these issues, so I'd be looking under the engine bay fuse box top tray for the large MasterFuses, checking the main Powerlink fuses on the battery connector plate, and generally test every fuse in the engine bay you can find.

The coloured blocks on the battery positive connection plate, are main Powerlink fuses for each system on the car.

Only because this happened to me with our C4GP and loads of different codes came up - but I am going with Fuel Pressure Sensor

Well out of my depth with later Berlingo electrics. But could the fault be a bad main earth. Had this on a truck before where I tested it by running a jump lead from negative terminal on battery to an unpainted bolt on the chassis. Or maybe earth bonding strap from engine / gearbox to chassis if later cars have them

Don't think it will be the Eloys fluid, my experience it flags up a Adblue fault and tells you the engine will stop in 500 miles. You car doesn't haVe Adblue does it?

May sound silly, open the bonnet and check the integrity of the two plastic triangular blocks either side just under the windscreen under the bonnet, are they damaged or wet? If damaged they should be replaced. Then check to see if any leaves are blocking the drain holes in the air vent tray, they are under the plastic blocks, the blocks can be removed. Check the sound proofing material that runs along the edge on the engine bay to see if it is wet. It has been known on occasion that in heavy rain, if the drain holes are blocked water can spill over into fuse box on the right hand side and cause all sorts of issues. Open the fuse box to see if water has got in there.

Worth a try. 

The spanner light refers the vehicle requiring a service, there are videos on you tube showing how to reset it by turning the key and holding one of the buttons on the right hand side under the dash down.

If you have been driving it 4000 miles with an overdue service, oil change, air filter, fuel filter etc it may be a little annoyed with you. When was the last time you changed the oil?

Could also be a wiring connector that has accidentally come apart. I had a car serviced and something replaced but the mechanic forgot to reconnect the sensors wiring connectors and the dash lit up like a Christmas tree and it went into emergency mode.

An update to the issue with my van and it turned out to be a failure of the fusebox in the engine bay.

Unfortunately my local garage didn't have the experience or knowledge to sort it and after it being shipped to another garage on monday, the fusebox was ordered from the manufacture and fitted, MOT'd and back on the road today, albeit £1500 lighter in the pocket as it failed it's MOT on several areas not related to the original problem.

I hope this may help others who have similar issues and help point them to getting a diagnosis
