    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 :eek: - 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.:confused::confused:

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

    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:rolleyes:;)

    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
