Mulla 308 1.6HDi:ssa oireili samanlailla (dieselin käry + sammuilu kiihdytyksissä) polttoaineensuodattimen vaihdon jälkeen, ilmeni että liitoksessa oli vuoto.
Kopioin laiskuutani tänne englanninkieliselle foorumille lähettämäni tekstin kommenttina hänelle, joka näytti uskovan valmistajan vikakoodeihin (taisivat olla (P087 ja P093). Myös tuo viestisi polttoainesuotimesta auttoi minua oikeille jäljille. Kiitos! Rohkenenpa epäillä jopa Teboilin venäläistä kuraaa jota tankkasin Kuusamoon kalaan mennessä ja heti alkoi pollution valo palamaan!

Neither of those codes told the essential, whilst OBD Fusion program (for iPad) made me possible to monitor the graphs of fuel pressure, fuel rate, MAF and RPM simultaneously. By load (rpm > about 2500) the engine stalled. Especially then, the behavior of fuel pressure and fuel rate was crazy, whilst then graphs of MAF and RPM were as they should.
I made the conclusion that the cheapest way to search the solution would be to change the fuel filter. I did it with total cost 75 € (30 the filter and 45 the work). Now all of the four graphs go in tact, and the problem seems to be resolved. The diesel smell from engine room is away, as well.
This issue makes me, again, to criticize the information coming from manufacturer's code, and from people in Peugeot service. Why to speak about "large leak" because there were no any leaks. Why not to give the information: "Serious problem in fuel rate in relation to fuel pressure", or "Contradictory behavior of fuel rate and fuel pressure", for example ?!!! This would, IMMEDIATELY refer to obstacles on fuel line which is almost the simplest and cheapest way to start to study the problem. Of course the problem would be in many other places but one should always start with the simplest one!
