I have an 03 plate Discovery TD5 that has developed an sudden loss of power.

There is no smoke and no misfire - just no power.

There is a distinct lack of Turbo boost but pre turbo power also seems a little rubbish.

I have unplugged the Map, Maf and Turbo waste gate sensors - this made no difference

The intercooler pipes seem ok - no delamination or leaks.

The turbo is spinning and the waste gate seems to move ok (by hand)

There doesn't seem to be any oil at the ECU - thats gotta be a first

The fuel pump seems to be working ok

No dash lights

I do know the fuel pressure reg is a bit iffy with a very slight leak.

I'm a bit flumoxed really.

Any more ideas before I give in and take it to a garage?

You have changed the fuel and air filtre.
Experience of fuel pump problem it will start to missfire when you boot it, but fine ploding along

Thanks gang

I'm getting the local Landrover guys to put it on the notebook tomorrow.

Hopefully that will give me a starting point.

I hate taking my car to the garage for anything - it makes me feel like a failure

I still reckon it's something fairly minor.

The cam position sensor is indeed a possible problem.

Had the same with my diso td5 03 auto (62k).

I changed :- Maf sensor, fuel filter, injector wiring loom (oil present at the ecu) re-wired other part of injection loom to ecu to rule out remaining oil making it's way out ............ none of this worked !

It was the fuel pump ....... 30 min job to change and the best price i found was Island 4X4 (kent) mail order.

Good luck

Col.
