Hi paul here can you help? i have a peugeot expert hdi van 2002. i had a little bang from it and now it gives a lot of black smoke and has no power when i try to go faster, do you think this may be the turbo, if so can you tell me how this is done
Re: Hi paul here can you help? i have a peugeot expert...
Hi ,
you need to check the air pipes from the turbo as it sounds like you`ve blown a pipe they fail due to oil inside,quite a common problem and not expesive to fix

no i dont think so ,more than likely its ERG valve ,thats the valve that open and allows exhaust gas into teh inlet manifold ,pull the rubber vac pipe off of it and try that next before you spend any cash .If it wasnt smoking before you changed the turbo then it shouldnt smoke now unless you have a faulty ERG valve or you have managed to manually open the operating mechanism and after my joey doing the same thing on a citreon (same engine) and giving me a proverbial headache till i noticed what he had done he had fitted the operating arm on the side of the movement so it was open when it should have been closed ,boy did he get the proverbial verbal ,a so called apprentice trained peugeot mechanic ?? he hasnt lived it down yet and i wont let him because he winds me up about the time i put the oil in and no sump plug .Or the time i the phone rang and i didnt tighten the wheel nuts.
The reason for the black smoke is that it is not getting enough air to burn the fuel completely.It could be a blocked air filter,obstruction in the air intake system,blown turbo,hole in tube between intake manifold and turbo,or a fault with the fuel system and injectors.
EGR is located at the back right hand side of the engine follow the silver pipe from inlet manifold , back and where it joins at the back of the lump , thats the egr!!
2x 8 mm bolts hold it in place + 5 mm allen screw if present secures a braket for wiring
window wipers off remove trim and there is 10 mm nuts, remove them, remove speedo cluster and radio etc, there is 2 10mm bolts below each end in footwells at end bottom of dash, 1 bolt below your ash tray in front of gearstick, u got to get gear stick surround out.
Hi, I have a 2.0HDI Expert which was doing the exact same thing as yours, blowing thick black smoke, sluggish and loss of power on gradients, a hissing sound and surging. I replaced the air flow meter but that didn't help. I was told to replace the turbo but a turbo expoert told me not to as it would blow white smoke if it was faulty. I was then told to replace the injectors but a diagnostic test showed them to be functioning fine. I was then told to look at the intercooler which had thick sludge at the lower left pipe. I replaced it today - Sunday 12th July and it is now driving like a new van. It now pulls me up gradients with ease in 4th and 5th instead of having to drop gear to get to the top. I got a replacement from Euro Car Parts for £147 inc VAT. To tell if this is your problem, look through the gaps in the lower section of the bumper at what looks like the radiator and look for sludge over the inside of the bumper and all over the pipe where it joins the back of the radiator (intercooler). Also open the bonnet and look down behind the grille for the same sludge. Hope this sorts it for you. Barry, Newtownards, Northern Ireland.
