Hi everyone, bought a 2003 'Kalahari' a few months ago. I used to own an old Disc and that was a good car but the Hippo is turning into a right ****. The dealer fitted a new clutch and DMF on purchase. A few weeks later the smell of diesel lead me to have a new HP fuel pump fitted, (£600) but now it's pluming black smoke!

Started on a motorway drive, hesitancy and drop in power; occasional 'pinking' followed by unbelievable amounts of black smoke. Warning light on occasionally, (whereupon it would improve slightly). After a day spent understanding the motor, I found that removing the Mass Air Sensor lead resulted in a drivable vehicle; a bit of smoke if your heavy footed but it will spin along a 70MPH and is only a bit short on power. So I spent £100 on a new e-bay Bosch sensor replacement but it makes no difference. Same symptoms with the new sensor fitted.

Anyone any ideas? I'm at my wits end here, money is tight and it's costing me a fortune.

Sorry if I have the forum protocol wrong, I don't normally do these things but the forum is so full of knowledgeable people I'm really hoping someone will give me a lead.

Welcome.
Have you checked all your turbo hoses for cracks, holes.
Sounds like an injector problem though.

Cheers Mike,
The hoses are certainly worn where they have been touching things but don't appear to be actually perforated. No hissing sound either and the turbo must be functioning to provide the power it has, no?
If it's an injector problem, would that be reduced by disconnecting the MAS? With the MAS unplugged it is almost acceptable.

Try cleaning the MAP sensor, youl find this on a search. You will need to remove the inlet manifold to access it as its on the underside. The total MAF signal also depends on an input from the MAP however by disconnecting the MAF you over-ride both. Worth a shot. Hope you get sorted.
