Good morning you lovely people
Driving the car this morning and I had a couple of warning throw up on the display...
"Engine Fault: Have the vehicle repaired"
and
""ESP/ASR system fault"
The esp I believe is the braking system. But the odd thing is that brakes are fine.
The big one is the Engine Fault. The engine is the 1.6 hdi Diesel.
The car drives ok until it is under load.
Driving at approx 30-40mph then put your foot down it starts to have a mild stutter.
Lift your foot off and it the engine revs ok.
Put your foot down again and the mild stutter returns.
It's almost feels like a miss fire.
I have an OBD2 reader and after updating it, it shows a code of P0087 which I believe is a low pressure fuel problem.
Would any of you lovely people have any ideas what could be causing this issue.
I'm thinking of having the Fuel Filter replaced and emptying & replacing any fuel in the tank, just to be on the safe side.

Re: C4 Pic 2014 Exclusive (B87) - Fuel Pressure Issue ?? I think ??
Ok, so here is the diagnosis for that code - quite involved! However, before doing anything I would suggest you look at my last point about the recall for your vehicle below.
However, whilst checking your vehicle, I need to inform you that there is a recall outstanding on this vehicle:
"An after-sales campaign must be carried out on this vehicle. Advise your client to make an appointment with their authorised dealer as soon as possible"
So I would ring your dealer, have the reg or VIN handy and tell them you have been advised there is a recall coming up as outstanding. I can't tell you what for - they keep that information internally.
Fault code | P0087 |
After sales description of the fault code | Fuel circuit: The pressure measured in the injection rail is less than the setting |
Description of the diagnostics | The measured pressure is below the reference value by more than 9% (For 1,2 seconds) |
Conditions of activation of the diagnostics | Engine running |
Conditions of disappearance of the fault | Driving for 5 minutes with several full load accelerations for 10 seconds |
Down-grade modes if fault present | Closing of the EGR (exhaust gas recycling) valve Irreversible deactivation of the vehicle speed limiter Irreversible deactivation of the vehicle cruise control Deactivation of taking account of the tight spot information Switching of the turbocharging pressure regulation to controlled mode Switching to fuel "normal reduced flow" mode;Sending of the information "torque uncertain" on the CAN network |
Switching on of the warning lamp and/or warning message | Warning lamp MIL Warning lamp STOP |
Main customer complaints likely | Jerking/stalling Lack of power Starting problem Slightly higher fuel consumption Fluid leak/smells (diesel fuel, oil, etc.) Cutting of the vehicle speed limiter Cutting of cruise control Difficult to engage gears Noise Engine acceleration at wrong time Smoke from the exhaust Absence of automatic stopping of the internal combustion engine (If the vehicle has the Stop and Start system) |
Suspect areas | Poor quality of the fuel or type of fuel Air leak on the fuel filter Clogging of the fuel filter Leak in fuel circuit (low pressure) Blockage on the low pressure fuel return circuit Fuel high pressure flow regulator high pressure fuel pump Pressure sensor on the fuel high-pressure injection rail Leak on the high pressure fuel pipes Leak on the fuel high pressure common injection rail Fuel injectors Electrical harnesses Connectors |
"An after-sales campaign must be carried out on this vehicle. Advise your client to make an appointment with their authorised dealer as soon as possible"
So I would ring your dealer, have the reg or VIN handy and tell them you have been advised there is a recall coming up as outstanding. I can't tell you what for - they keep that information internally.

Hi Marc,
Many thanks for your help.
I have the car booked in tomorrow for an MOT so I'll get them to check it out.
I might try the cheap fix of new Fuel Filter and drain & clean the fuel lines and get the injectors cleaned.
I phoned the Local Citroen dealer and the recall is for the Drive Belts and Tensioner.
I'll keep you posted.

Hi Marc,
Would you happen to have a diagram/illustration for replacing the fuel filter on this particular vehicle at all please.
I think the issue is down to rubbish/dirty fuel.
The fault code has gone and not returned and the car appears to running ok.
But I'm still going to replace the fuel filter, empty the fuel and clean everything out.
Cheers
Zane

Place the tray underneath the fuel bleed pipe outlet (When coupling the tool, protect yourself using a cloth to prevent any splashes of fuel). Disconnect and move aside the connector ( as "b") (Water in diesel fuel detector) (according to equipment). N.B.: The water in diesel detector acts as a lock for the water bleed screw (2) on the fuel filter. Unlock: The water bleed screw (2) (Clockwise); Raise the water bleed screw (2) fully (In the direction of the arrow ( as "c")). Allow the liquid to flow out. Disconnect and move aside the connector (as "a") (Fuel filter heater). Clean the unions (1), (3a), (3b) using the degreasing product, the brush and the cleaning tray. Uncouple the connectors (1), (3a), (3b). |
CAUTION: Plug the openings when a union is uncoupled using the tools [1520-B / 5705-T]. CAUTION: Close the pipes on the fuel filter, using the tools [0194-T]. Slacken the bolts (4) (captive screws). CAUTION: With great care, vertically disengage the fuel filter (5) from the fuel filter support (Risk of damage). Remove the fuel filter (5). |
CAUTION: The water in diesel fuel detector, the priming pump and the diesel fuel heater are integral with the cover (5a) of the fuel filter (5). If there is any anomaly, replace the fuel filter (5) cover (5a) in its entirety. Check that the centring ring is present (as "d"). CAUTION: Place the cover (5a) of the fuel filter (5) upside down, in a spot that is secure and clean. Remove:

Re: C4 Pic 2014 Exclusive (B87) - Fuel Pressure Issue ?? I think ??
Just changed the fuel filter on my 3008 with the same engine for the same fault... hopefully it has cured it! I was unable to get the 3 small TORX screws out and had to replace the entire filter and lid - manged to get an OE one from e-bay for just over £40. I didn't bother draining it first, just removed it full of fuel then emptied it once out. Depending on access you may need to dismantle half the car to get access to it!!
