Thread: Intermittent Loss of Power

Td5? If so then if unplugging the MAF results in an improvement, then its the MAF. Turbo hoses are another thing to check. They delaminate when they get old and giving it a boot full causes the hose to collapse internally blocking the airflow.

+1 As above + check for oil in the ECU red plug and if there is any replace the injector loom pronto(use only genuine)

I'm back. Firstly thank you gentlemen for taking the time to assist me. Well I replaced the MAF. Imagine my happiness at no more clouds of black smoke on take off. Unfortunately I'm now experiencing zero boost till I get to about 2k rpm. 😡
Doing my head in as I just can't seem to get her running properly. Wife won't drive it as it goes from one issue to the next.
SO......
Now that we know it's not the MAF (injector loom & clean ECU plug already done & I have silicone hoses) what should I start looking at next???? Massive turbo lag Will ultimately be dangerous as I'm used to her having a massive amount of get up & go.

Any help will be greatly appreciated.

check wastegate and associated linkages and hoses, check turbo impeller , see if someone has a nanocom up that way who can see whats happening on live readings.

Hi, do you still have EGR?, if yes see if the valve is not clogged with muck also see the MAP/IAT sensor(in the inlet manifold) to not be gunked, for this low boost issue you really need a tester to see some live data cos it can be the AAP sensor too(in the airbox), the air and fuel filters are OK?

Maybe injector washers are starting to go?

ERG was already blanked when I bought her.

I will have to get it plugged in (was going to buy one but unsure if I'm going to keep her). I've had her about 3 months. It has had 200k service, New Injector Harness, sump gasket, xyz switch, abs module, new battery, MAF, MAP cleaned, etc (it's 0149 & I can't remember what else I've done).



I truly love her but she is breaking my heart. It's like each time I get on top of something it leads to something else. Really thought a new MAF would finally see me driving with a Disco 2 smile on my dial.

I've tested the MAF & it's working. When I unplug it I get my power back but also the black Smoke cloud eminating from the tail under load and takeoff.

Sorry for the vent. The rig is just getting the better of me at the moment.

Ok. I'm ready to get on with it after my little cry. Am now think it could be boost modulator. From the symptoms I've previously posted would anyone agree it could be this part?
Are there any issues doing the Defender bypassing it for a full week while I wait for the part to come in?

Again thank you for everyone's help & time. Once I can get her running properly I'll be a more positive member of AULRO, positing pics & adventures but for now I've got to get her to the point I can drive her without crying. Lol
