Re: 1999 406 hdi faults
Hi, As far as i know they are the same and you should have no problem fitting them but if you want to make sure just go into any car spares shop and they can cross referance the part for you. But im sure the engines are the same as most of them have used the same engine across the range. As long as its the same size engine then you should be ok and have no problems. Let me know if you have any problems and ill assist you the best i can

expensive to repair properly,quick fix??? fit two non return valves ,one in the feed and one in the return to the injector pump ,weither conventional pump or common rail pump .this will cure your problem and its cheap to do ,two valves (observe direction) in the lines .works every time on any diesel engine weither its plant or road use
The electrovalve that controls the turbo waste gate needs to be changed it costs around £40. It is located on the front lower part of the engine block. I have done lots of them they are a common fault after about 50000 miles.
Thes have a weak point with the pump in the tank. It is under a cap under the rear seat, get someone to turn the ignition on and listen if no noise give it a tap and see if it whirrs, slacken a pipe on the filter and see if there is pressure, if not the pumps are available from factors or on line.
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.
Injectors from the same ccm engine are most probably sounds same but to be on the safe side check not only the shape but code on the top of injector too. Because they are piezo effect injectors and set by the manufacture for a specific pressure for specific engine codes.
