I always say this: "Have you tried injector cleaner in the fuel?" Bits of crap mess them up. I put in STP but, I suspect they are all much of a muchness. And it's a cheap fix if it works.

Yes, if you have the car checked on Peugeot Planet, it will give you fault codes. The diesel mechanic may have them, assuming that he found some. Otherwise if injector cleaner doesn't work, you'd be best having someone connect your car to PP.
