1.4HDI 2011 model amber engine management light

Hi,
Firstly may i say a big hello to all in the forum, my name is Mark, I am new to this site after it was recommended by a friend.
I am in need of some advice with regards to my C3, 1.4HDI.
My vehicle has covered 47000 miles of mostly motorway mileage as this is used daily to commute. Due to my work shifts and times it is extremely rare that my car is sitting in traffic and usually has a good 60 mile a night run down the motorway at approx 60MPH
Until yesterday the car has been running fine with no issues what so ever & a great fuel consumption.
Whilst on my way to work on Sunday evening whilst travelling along the motorway with the cruise control set at 60 mph, a loud bleep sounded followed by the amber engine management light on the rev counter cluster, this was also accompanied by a message on the LCD display which read the following "Engine Fault" The engine management light since had remained on and as soon as I start the vehicle the alarm sounds followed by the engine fault message. There appears to be no drop in performance at present, I am also monitoring the fuel consumption. The service light does not activate when the alarm sounds and the engine management light is solid & not flashing. I have referred to the Citroen hand book for my car which states if the light come on steady it's a minor fault?
I would be most grateful if any member could give me some advice on this and how to clear if it can be. I have tried to driver the vehicle in a low gear at higher revs to regenerate the exhaust DPF but still unable to clear this fault.
Does my car need to go to a Citroen main dealer for diagnosis or do most local garages now have the software to read the faults?
My friend does have a fault code reader which he has offered to borrow me, but I have not got the faintest idea where the OBD port is on the C3.
Any advice on this matter would be greatly appreciated, and I thank you all in advance for your kind assistance.
Regards,
Mark.

Hi anorakmark

Yes, the engine ECU has recorded a fault. It should be investigated and cured.

If you suspect the DPF/FAP system needs regeneration, you should try some DPF Cleaner fulid in the fuel tank. Its a cheap and easy to cover that fault and a bit of driving in the wrong gear isn't going to fix it.

Obviously reading the codes would be a good place to start, look in the glove box area for the OBD port.
But a much more useful diagnostic tool is Lexia/Diagbox

Hi,
Thanks everybody for your kind help. I have had the fault codes read today and i have the following

P2562 Turbocharger Boost Control Position Sensor A. The reason of Citroen C3 P2562 OBD-II Engine Trouble Code is P2562
Turbocharger Boost Control Position Sensor A Circuit.

P2564 Turbocharger Boost Control Position Sensor A Circuit Low. The reason of Citroen C3 P2564 OBD-II Engine Trouble Code is P2564 Turbocharger Boost Control Position Sensor A Circuit Low.

I have cleared the faults and so far have travelled approx 40 miles with no fault.

Can anybody give me some idea if its a big job to replace this boost control sensor, can the diy mechanic do the task or is it a Citroen main dealer specialist job.

Kind regards,

Mark.

Hi Mark , I know its 5 years since you posted p2562 turbo boost code ...but i have same p2562 engine light also on a 2012 1.4 hdi vtr.. when i clear code it doesnt immediately coem back on ... usually after a 10 mile drive and turning engine off once or twice... first time i even drove 120 miles before it came back on , the eml . I want to swap out the module and see if that cures it before taking to mechanic. Mechanic says it could be vaccuum pipes leak but I dont know.... the Module is cheap so I just wondered did you put a new one in and fix your problem .

Also if anyone else reading this .. i cant seem to find exact oem code on the turbo boost module. Are they all the same specs for this 1.4 hdi diesel engine ? Its a very common engine so will any module do the job if i cant find exact match to my VIN or reg number ....?

thanks

this is a follow up to my last message a year ago . I fixed problem and I meant to post this immediately after but forgot.
I had a malfunction/fail of the turbo boost control module , also called pressure convertor valve. It takes exhaust gas to operate it and I assume it got gunged up after 9 years of use. I fixed this myself buying from ebay taking note to take lots of photos of one on car so that replacemnet looks EXACTLY the same. I also went to a local mechanic with good feedback and explained problem and what I think solution was seeing as this engine is used in Fords etc and millions made with known issues... I observed his body language ( because I dont want to be ripped off !) and unfortunately ( because I was recommended by intelligent people he was 'honest')..I expected/hoped he would say " oh yes .. i know what the problem will be the boost valve is clogged after 10 years of diesel gunge ..replace that low cost item and see where we are then..." but no I didnt get that response...he was non commital and talked baout checking for vacuum leaks etc... so .. I decided to do myself ...this is what i bought off ebay : Pressure Converter Valve fits CITROEN C3 SC 1.4D 2009 on Lemark 1618QH 1618QQ
and from this company on ebay 'carpartsinmotion'

there are other modules that look similar and cheaper so you could risk getting a cheaper one but I went with this and it fixed problem.

Was a bit fiddly to get old one off , working on car parked in street but its do-able... just be careful with the electrical plug ..its a bad design where you have to try get a screwdriver blade down to unhook some plastic and was a pain .

A garage could easily take advantage of unwary by saying you need a new turbo and then you are into possible £1000's with the labour.

I also found some useful youtube videos where they replace these modules .

This : https://youtu.be/AWzVGyyIZS0?t=882 this is how to remove the module at about 15 mins mark.

I hope this is informative to someone and stops being ripped off by garages. I was surprised this not in this forum until now because most old diesel Citroens must have this issue, but none has mentioned it hardly.... Good luck!
