Challenging Diesel Problem!

Hoping some of you 'good guys' on here can help. Friend of mine has a Freelander TD4 Automatic that was exhibiting all the symptoms of a faulty MAF. I advised him to unplug the MAF which he did and all the performance came back but with the engine management light on.

So, he bought a genuine Bosch MAF, plugged it in but had no effect, in fact the thing was worse!

He then took it to the local Landy dealership who checked the following list of things.

T4 Check - no faults

Replaced MAF with known working one.

Check all turbo hoses

Clean and chech EGR

Clean MAP Sensor

Smoke test intercooler

Fit new fuel filter

Vac hose to turbo actuator

Change turbo actuator

Check exhaust for blockages.



I'm sure it cannot be turbo related as the thing goes like the proverbial poo off a shovel with the MAF unplugged. With it plugged in, the engine will only rev very slowly to 2200 rpm and no further!

The dealer has told him the only thing they think it can be now is the ECU but they can only fit one at a non-returnable charge of £700 and they're not sure that will fix it - I'm pretty sure it won't!

Now the EML is on all the time!

Any help / suggestions greatly appreciated even though it's not a 75 or ZT, just a close relative!
