    I took the MH to Towtal yesterday to have my new towbar fitted.

    Fiat 2.8 JTD 2002

    On the way there (and back) the injector warning light would pop on then off, especially if I backed off the throttle a bit. I could pull 70 to 80 mph easily with no problem but if I hit 2800 revs in 4th it would pop on and if the engine was loaded eg. when going up an incline but still pulling well.

    It appears to be very intermittent.

    Any ideas?

    Thanks in advance.

    BTW

    The new towbar is brilliant but the wind and cold cut us in half whilst we had to walk around Hanley for a few hours while it was being made and fitted.

    any chance the guy who fitted towbar has somehow buggered up the wiring?
    last time I had a towbar fitted they stuffed up the piping to my water tank.perhaps youhave had some wires disturbed.

    Looks like it was happening before the fitting as he says it was happening on the way there and back.

    injector wiring has been a problem on that model as in its too short and pulls on the connectors you can reroute this a bit to help and check the connections are tight on tight plugs be careful not to mix them up you can sometimes tighten the plug by squeezing it carefully so as not to break it.That would be my best guess.

    Never let the truth get in the way of blaming the last man (usually a fitter) getting the blame:Doh:

    Check around the fuel filter housing/hand pump as these can be known to leak and cause low pressure. Check the injector loom is attached properly, as these are known to be a little short on some vehicles and can pull out. If all avenues have been tested, then have the injectors/injector seals looked at

    To be honest I have had a look at the new Towbar fitting and they have done a fantastic job :)

    I would easily recomend them...

    Just to give further information....It only seems to do it when its warm/hot....I took it to 3500 revs when cold and it was fine....came back after a short run and it started doing it and I noticed the engine had reached operating temp...slight loss of power too until I backed of then accelerted again...would this be the ecu cutting into "get you home mode"?

    A squirt of WD40 ans a pair of mole grips on the little arm arrowed.
    You will need to get under the van by the door area, from behind the front wheel, depending on the van you may need to lift it, so care needed.
    Look up the back of the engine & identify the turbo which will look similar but not identical to the picture.
    Doesn't take much effort & it doesn't move very far so do not force it.

    Light on at 2800rpm

    I had similar problem, here is an extract of a post 18th March

    I bought my MH private. Fiat Ducato 2.8JTD. My red MIL came on at 2800 rpm. Then went out when foot off gas. Not too bothered as son has garage. Plugged it in, came up as "overboost". No problem says son, bet waste-gate on turbo seized. Yes it was. Free it and hey presto and it revved freely. However, the red MIL indicates an injector problem. Well yes in a way, as due to overboosting the ECU shuts off fuel to the injectors, so the message WE GET (humans!) is injector problem.
    I had cause to ask previous owner about something else, he said light came on and he thought it was to prevent over-revving.
    Seems it had been seized when stood idle at the dealers some time before he purchased it.

    The fault came up as a P0235 fault code.
    Good luck and keep us informed.

    fixed mine

    HI There

    used the pic and info on this thread. Very useful, My warning light was coming on when going up hills or accelerating to overtake, sometimes power was lost and you had to fiddle with revving back and gear changes to get it going again. Called AA out this morning as the light was on a lot, plugged in computer and no fault codes were there. So we ( me and AA) went for a ride, demoed the problem, but as there were no obviousl faults codes or wires or pipes off all they could do was reccomend me to take it to an expert.

    So I thought I would find the turbo and look at the wastegate. Found it ( hard to reach crawling under van) few sqirts near pivot point on arm, used mole grips and gradually freed it off, being careful as I dont know how far it is supposed to move. Anyway got it moving and went for a run - feels better and no lights!

    SO Many thanks must have saved me a fortune..:RollEyes:

    So you did consult an expert. You consulted MOTORHOME FUN!

    Well worth every penny of £10 for the info, I know mine was well spent.

    Glad it worked, knowing you deprived a Fiat Main Stealer of cash is the best bit though!

    next job

    Yep thanks

    Now on to another task, stopping the creaking in the worktop/cabinet work near the cooker- its a dakota. Found the culprit, I think its the metal plate behind the cooker squeaking agains the woodwork - not the cabs - when I take it out ( its just jammed behnd the work top) Its hard to make it creak - as soon as its in then I can hear a creak when I lean on the cabinet. Its been getting on my wick for over a year now . Had to remove the cooker though to find it.:Confused:

    I'm sure I heard recently that any warning light showing will now mean a failed MOT. That could be a problem.
