D2 2000 TD5 black smoke

[DWN06]

Hi all my TD5 still blowing lots of black smoke under load have done the below to try and fix.

replaced wireing loom complete
replaced ECU, MAP, MAF improved get up and go of the engine
new exhaust system
removed EGR
replaced boost swtich (near AC compressor)
freed up waste gate
it still surges with cruise control on
fiitted provent 200
bought nancom still not how to tell were it tell me how it's over fueling
can anyone give me some more clues on how to stop the black soot asd it never happened until the oil in the wiring loom???:confused:

Check the turbo hoses for de-lamination, don't be fooled if they look okay on the outside :)
It's either getting too much fuel or not enough air :)

[bblaze]

first thing I would check is blocked air filter element, then as above, condition of all intake system

Good Morning

have used my nancom this morning found these codes not sure what they should be

Config tune: STTDP007
Fuel Tune: STHDE 017

where can i find what setting should be?

[Tombie]

They are just your fuel map identifiers...

You need to either:

Replace your hoses with Silicone ones

Or Your waste gate is jammed open / sticking


You should replace the hoses anyway :) Bet it fixes the problem

[OffTrack]

To add my voice to the chorus:

Replace your turbo hoses and check the air filter.

[DWN06]

Hi all

have replaced hoses today the old one looked ok, se how we go. air filter id only 5K old.

Have you checked with your Nanocom that your MAF is providing a reading?

[DWN06]

well thing can only get better got letter today from RTA, someone reported my car blowing to much black smoke, have to take it in for them to check now.

[mattg]

Are you using oil?

Compression test through injector wholes and while your at I'd replace injector washers and o rings

How many km on the clock.

Cheers Matt

Hi Matt

no not using any oil, but have disconnected the MAP sensor no more black smoke loss i little power (no more over fueling)

[mattg]

I recon map is your issue then

[DWN06]

Hi matt

would my local LR dealer know how to fix that?

Maybe. do you mean the plug near the air cleaner it plugs into the cylinder with the box on it about the size of a matchbox. That is the MAF or Mass Air flow sensor. If that is unplugged and it stopped the smoke then replacing that is just the hose clamps. Do it yourself. Where are you? Someone close by might have a spare that they can lend you for diagnostics. Hope this helps I would steer clear of the stealer.... sorry meant dealer. They will charge a fortune for a MAF check EBay. Cheers Matt

Hi matt

no the MAP it's on the inlet manifold and it's only a month old. the MAF is only two months old. I am now in Canberra.

If it is only a month old I'd take it back to where you got it. warranty replacement. I havent had a MAP issue so others might be able to guide better but. I recon if your smoke stopped after that was unplagged its not working.

Hi matt

swapped the MAP for another one still blows smoke.
not sure where to go next?

[biggin]

MAP?:confused:
Is that the same as the ambient air pressure (AAP) sensor?

Anyway whatever it is, if no smoke when disconnected, and smoke when connected, to two different good senors, then I would be looking for a cable/connector problem.:(

And what the other sensors are reading as well.

MAP/IAT sensor (manifold absolute pressure/intake air temp ) is mounted on the intake manifold.

Agreed re the wiring.

[DWN06]

all senors are reading ok, maybe the ecu map could be the cause as it was second hand, as new one was not able to get at the time. it is not able to be programmed.

What is the part number on the ECU? It should start with MSB and will be on the outside of the case.

Do you have a sd card for the nanocom? If so it might be helpful if you record the fuelling inputs while taking it for a drive and post up the file.

Guy. Did you end up sorting this? I am interested to know what was the outcome.

[DWN06]

Hi Dave

yeh spent another 2k got new ECU and got it mapped has stopped the black smoke by a long way.

[d2dave]

When you say by a long way, do you mean it has stopped totally, or you still have some?

[DWN06]

Hi dave

it's mostly gone only appears mostly going from 2nd to 3rd gear i am happy with the resutls
