    Underpowered disco auto and black smoke

    Do you mean the maf in the air intake pipe? If so I have unplugged that before and took it for a drive, it made no difference whatsoever

    Underpowered disco auto and black smoke

    I've unplugged the sensor on injector no4 and the black smoke has gone, I'm now getting a little white smoke. Also as I've unplugged the sensor the engine check light has come on and put the car in limp mode so I can't check if the power is back or not. Looks like I'll have to source and fit a...

    Underpowered disco auto and black smoke

    My sensor is on number 4 injector, the one closest to the bulkhead. If I just unplug it will it cause any other issues in regards to running? Also I have noticed the injector appears to be seated a little higher than the other 3, not sure if it's meant to be like that. I did remove in and try...

    Underpowered disco auto and black smoke

    I actually own a snap on modis ultra scanner. I have scanned it but it gave no fault codes, I ran live data and from what I could see everything appeared to be functioning correctly. The egr valve has already been removed. How difficult is it and what parts would be required to remove the whole edc?

    Underpowered disco auto and black smoke

    What's the best product for cleaning out the intercooler? I've removed the pipes and they don't seem too bad but thought I might as well put something in the intercooler and flush it through whilst I've got the pipes off

    Underpowered disco auto and black smoke

    I'll check the turbo blades today, I'll also remove the intercooler and pipe work and give it all a good clean out. Fingers crossed I find the culprit as I really don't want to part with the car but I need something fully functional quickly as this was meant to be our daily car

    I'll check that today, although when the hoses were off I could hear the turbo whistling away and I can't hear the turbo at all with the hoses attached

    Underpowered disco auto and black smoke

    The transmission does kick down. The engine speed isn't higher though, I presume you mean like a slipping clutch?

    Had all hoses off, took it for a drive, no difference at all, all hoses cleaned out and refitted, still no different. Any further suggestions?

    Underpowered disco auto and black smoke

    Thank you, I'll check all the hoses tomorrow as it's currently pouring it down, I'll update tomorrow once I've done them, I'll also remove them and take the car for a drive as suggested and see if it's any better

    Which are the air intake hoses? One thing I did find odd was when I opened the air box to replace the filter there wasn't one in there

    Underpowered disco auto and black smoke

    Hi all, just after a bit of help please. I've just purchased a 98 disco 300 tdi auto and I'm already having problems. I'm getting black smoke no matter what speed I'm doing, none at idle though, also the car is gutless, I can do motorway speeds and keep up with normal traffic conditions however...
