Hi everyone,

I'm not used to posting on forums and have desperately scoured many recently looking for solutions to my problem(s). I figured/hoped that the easiest thing for me to do now is post on a forum and see if anyone can offer me any specific advice.

My car is: Peugeot 207 CC Convertible MK1 Facelift 1.6 HDi FAP Sport 2dr (125 g/km 110bhp)
It was running fine with no problems or warning signs and suddenly on a roughly 10 mile journey I noticed it was running slightly rougher than normal which at the time I thought nothing of, anyway when I came back to the car later that day to go home I could not get it to start and the RAC recovered it back to my home, it started enough to be loaded on the transporter but produced a LOT of white smoke and really smelt bad.

Sometimes the car will start, others it won't, most of the time it limits the revs usually in 1,000 RPM blocks e.g. won't go past 2,000 some days or 3,000 others, if left idle to warm it usually gets better but I don't trust it enough to drive it so it's actually SORN'd whilst I try and work out what exactly is wrong.

I splurged the cash on a full chip scanner with diagbox and got reports inc wiping faults and seeing what came back... as soon as the key is turned without fail I get an error code of:

P2291 : Starting monitoring.
Fault characterisation : The rise in pressure in the injection rail is too slow on starting
Status : intermittent

When the engine is left to run long enough, the car has been started a few times or revved a bit, these other faults are added to the list:

I tried swapping the MAP sensor using both a new part and a known working one from another car which made no difference and tried a used part from a working car of another similar sensor too.

Any advice would really be much appreciated.

Thanks in advance and hope you are all staying safe and well

My guess based on codes is you have a faulty injector with is sticking and has a high leak off affecting fuel pressure and giving white smoke less likely but possible is the hp fuel pump or its pressure regulator

Thank you for your response. According to the bills I have the previous owner had 4 new injector seals fitted about 17 months ago.

I don't want to sink too much money in to the car so would look at doing the cheapest options first. Could you link me to any of the parts you refer please? Be that by image, part number and/or links so I know we are talking about the same thing, please.

Much appreciated.

P14A4 and boost issues, carbon build up.
Possibly due to an injector/s chuffing, faulty egr, turbo or boost leak.
Fix the blockage then the fault.

Thanks Carnie, I'm considering taking the EGR valve off for a clean and checking injectors as my next steps in trying to resolve the problem.

Thanks again for the advice.

Regards.

Good call, carpet cleaner foam works great for cleaning the intake system whilst running and doesn't cause run on. Also cheap.
Remember P14A4 is cold/intake EGR not exhaust. Before you strip the wrong one. Not saying you were, just a common mistake.

Thanks for the tip, didn't know about the carpet cleaner foam trick. I'm always a fan of a cheap solution!

Yeah the Diagbox fault characterisation says the cold side is jammed shut so I'm hoping it's as simple as that.

I'll post back on the forum once I've had chance to get to get this done.
