Hi , i am a newbie and i joined up to the forum nearly 2 years ago since i bought my car and i havent needed any advice as the car has been so reliable until now , a couple of times in the last 2 weeks when i have come to start it in the morning it turns over fast but the engine doesnt fire then after a few attempt it eventually starts , i`m not sure if it a coincidence but the radio had to put on standby before it would fire , any how it can then be ok for a couple of days then it will struggle again , when it does finally start the idle is a little lumpy similar to if there was a glow plug down and then it will settle , yesterday it did the non start thing and eventually fired up but when it came to turn the car off the engine kept running for about 4 seconds then turned off , ive been out today and there hasnt been any problem , started first time and turned off fine , there are no power issues , when it is running it is perfect , its just the ocassional difficult starting and the run on after the key has been turned off , i am going to try and get it scanned this next week but as the engine light hasnt been on i`m not sure if anything will be found , i hope someone can assist and advise , thanks in advance , simon

The symptoms you are describing are very common of a failing fuel pressure regulator. It is the plastic piece bolted to the side of the high pressure pump, often the internal seals start to break down and need replacing (you can order these from the dealer) or replace with a new or known working unit. This should solve all the issues you have described.

Hi fattail95, thanks for your reply , now i have somewhere to start i can try and find the solution , be it a new regulator , i did some digging today and came across a site called hdi tuning which within the information section it describes the run on and what causes it , is this regulator easy enough to change or is going to be a pain , again the car seems to have been fine again today but once it has happened once it will surely happen again at some point , also how much roughly am i looking at for a regulator do you think , again thanks for getting back to me , thanks in advance, simon

I would concur. The regulator is not to difficult to change, it is located on the back of the HP pump, usually held on with a couple of torx or philips screws, you will need a 1/4" drive ratchet to get in there or a short torx key, in addition to the screws there is a plug to remove. You will need to remove the fuel filter also not very difficult.

You can probably get a secondhand one on ebay for not to much money, the problem is usually that the attached filter gets clogged but it very difficult to clean, some of them don't have a filter.

Hi peter , thanks for your most helpful information , it does seem like this is the problem , been on the bosch parts website tonight and it has all parts number bosch wise that is on the car and there are 2 part numbers for this part , the ebay listings from the link you provided , some are from poland and lithuania , should i be worried if i bought 1 from these sellers , anyhow i will be getting this sorted when i get paid next week, out of interest peter do you sometimes post on honest john at all , if so you have helped me in the past with my old 405 , thanks in advance , simon

Hi Simon

I have bought secondhand ones with some success in the past for a lot less money. If you have any scrap yards down your way you may be able to get one, there is probably a better chance of one of those working properly than an unknown new one.

I do post on several forums so its quite likely we have crossed paths before.

Hi Simon, and welcome.

There are 2 types available, I believe one is for the 2.0hdi, and another for a 2.2Hdi - either will be fine.

I have a spare one here if you are local and want to try it out..?

I bought a brand new genuine Bosch unit from Poland and it arrived quickly and worked perfectly, as expected

Hi ginger magic , thanks for your reply and kind offer , im in nottingham so a little far , fattail , i have seen the ebay listing for the regulators from poland and lithuania but not sure if i trust them , a little too far fr them to reply to a possible complaint or return for whatever reason , there is however 1 on the diesel parts direct site for £140 , i dont mind paying that if for peace of mind only , well i have had another hard start and an engine run on , i have spoke to a mechanic friend of mine and he says that the run on and engine starts are related and this regulator will solve this , i have had so many people saying it is a failed injection pump and injectors but i dont think i would be able to do 70mph if that was the case as i have been , only thing i am confused about is that the bosch website is showing 2 parts numbers for the regulator and im not sure why , the website is saying i should have 0281002872 and these websites are stating that 0281002493 is the replacement i should get , i do have the part number 0281002493 fitted on the car at the min so will prob go with that , i will keep you updated to ensure that if anyone else has issues like me then hopefully this will help them out , thanks in advance , simon

What about this one?

Looks genuine.

Hi all , thought i would post an update , last week i had the car in with a peugeot / citroen specialist and gave him the symptoms , 3 days later and 300 quid lighter i had the car back , he said he had done diagnostics on it and checked the live data and all looked normal but he couldnt find anything wrong , he noted that the engine was turning over slower so he changed the starter motor , any how for 4 days the car worked fine until yesterday morning , it struggled to start , was cranking over fine just wouldnt fire and took a few minutes to start it , got to work and it ran on again for a few seconds , but wouldnt restart , i had the rac out to me last night and he put his diagnostic scanner on it and it came up with 3 faults , maf sensor , cooling fan fault and although these 2 wouldnt cause a non start , the third however he said would , P0215 - injection system relay , i cant find much information on this , maybe someone knows what i am looking for , also once the engine is hot and idling it seems to drop slightly and rev back up so it stays at idle speed , i am getting to the end of my tether and due to last weeks waste of time and money i am now short on funds , i hope someone can help me , thanks in advance , simon

Simon,
I feel for you, I really do
First things first, stay away from said specialist, unless you're trying to get some money back
I have pp2000 & would happily run a diagnosis check on your car for you, I can only do Sunday afternoon's
at the moment or Saturday afternoon in a couple of weeks.
I'm in Thringstone , near Coalville if it's any help to you.
All the best DDD.

That's good that is, don't know what's wrong so replace something completely unrelated and charge the owner a fortune. Wish I'd thought of that. Damn these morals...

The "injection relay" is the usual bit that gets replaced on HDis when they can't think of anything else, it's in the box with the engine ecu (if it has one, in later cars it's part of the ecu). They do go intermittent (engine cuts out) or dead (engine won't start, fuel pump doesn't run).

The list of doom says fuel cut off relay - I thought these just shut the injectors off

I think these are usually the fuel pressure regulator but some decent diagnostics with PP won't go amiss.
