Hi folks
Last time I spoke to CharlesY he rightley said check the fuel system from front to back which i did, replaced lift pump airfilter cleaned out sediment filter
check for air leakes at tank by pipe
But help stil pulls away like a 1 legged camel !!
once the turbo kicks in she flies but at low revs and it seems worse when cold
just wont pull also when i first fire her up struggles to pick up until i have let it run for a few minuets
i cant find air leak thats what it seems like any ideas please
 
I get that ^^^^^ feeling everyday in mine two, just thought it was 2ton of motor tring to move with no power without the turbo

I have had series lanies no turbo at least i could pull away on a slope with out thinking i should be in low range !:eek:
 
Is this just normal for a disco 200tdi? Can anyone enlighten us?:confused:

Also I have noticed I cannot move my the wastegate by hand?? Is it stuck or is this right? Can hear turbo whistle from around 200rpm when it kicks in and have some power:confused:

Perhaps it is only me and you with horse drawn disco,s
out of interest checked my waste gate a few months ago to adjust to 1/2"
rod as explained on here and the gate wont move by hand just thought was normal as mine hits the turbo and then we are flyin!
 
The waste gate rod needs a stout shove to move it. A lot more than you might think. A pull or push of about 30 pounds might be required.

Once again I suggest you clean the boost compensator on the injection pump. If it's not perfectly free to move all sorts of strange fuelling problems can occur.

If the engine runs fine once the speed is up a bit, there can't be a lot wrong, so all you need do it find the problem and fix it!

One thing at a time ...

I have found http://www.stonefisk.com/doc-arc/def_man/ThermoGuard_Tdi_Tuning_Rev.2.pdf document but the author claims to be no expert could someone please confirm the content before I tackle my pump,

Thanks
 
Cheers charlesY I was hoping you would reply :D,

Is WD40 and a lint free rag ok for cleaning the compensator?

I have noticed that the tamper cap on top of the compensator is missing so guess it may have been played with before.

Also when my engine is cold may throttle seem sticky on release when changing gear feel like it is slaping my foot. Not sure it's connected all. The cable is ok.
 
Hi folks
whent for a good drive today aprox 25miles flat out after that have decent take of power and runs well at pre turbo conditions

Yes. That will be a fine combo.

Hmmm... when you get suspicions, you take extra care!
Be sure also to check the boost pipe all the way, end to end.

Time to sort out the pedal pivot? Get your head into the corner of the floor and the WD40, and make sure the pedal swings freely on the pivot. If it is sticky now, it isn't going to get any better - until you sort it. I don't much like the sound of the foot-slapping carry-on!

Run the tank till it it is low, and toss in a can of diesel injector cleaner. Sometimes it does miracles.

You'll sort it soon.

Cheers charles,
all being well. I.e. not ****ing it down or snowing will take the top off and give it a good clean and get busy with the Wd40 ;)

Will let you know :)

I never travel 'flat out' i have 177'000 miles on the clock and would like at least another 50'000 more :D 4000rpm and 75mph max for me :D my engine is in good condtion apart from this minor problem, and would like to keep it that way :)
 
Oooooooooo, seem better after a run but never great, guess that could be the pump casing expanding faster than the shaft on the compensator valve.

Have you had a read of that document I found?
 
have you changed your fuel filter and cleaned out the sedimentor bowl recently. If not try it and see if that helps.
