Defender 110 td5 garage near Alta?

[Zakkie]

Hi Landrover friends, we are currently on a trip from the Netherlands via norway Finland and back

Since today my Defender 110td5 (2001) loses power in higher revs f.e. when I need to drive uphill and shift from 5 tot 4. Its the same in every gear, when I accalerate to a certain revcount the engine starts to shake a bit like its not running on all 5 cilinders and it can almost not accelarate beyond that.

Engine seems to sound fine though, turbo sounds like its working. Oil, coolant are good, airfilter seems fine

 

 

Im looking for a garage that can help with my Defender . We are currently at Badderen between Storslett and Alta. (Alta would be best since we already are going in that direction)

 

Any tips for a good garage that f.e. should be able to at least read the computer would be appreciated

Sounds like the turbo is overboosting.

When it does the ECU cuts fuel and the engine won't accelerate.

Typically in high revs.

Check if the valve that controls how much exhaust that goes through the turbo is working freely.

If you disconnect the rod from the actuator you should be able to move the valve in the turbo easy with your fingers.

Yup. Could be worth trying to check/release the wastgate valve. Easily done with a set of pliers/wise grips and some light oil/penetratign fluid (wd40 etc) These tend to get stuck over time, and the result can either be overboosting (stuck partly closed) or not beeing able to build up enough preassure (stuck open).

 

Overboosting will result in a fault strored on the ecu, and this needs to be cleared. If there are someone in the area with a Nanocom or other diagnisis tool, this is done in a few minutes.

It could also simply be a clogged fuelfilter. I had similar symtoms one mine a short while ago. Didnt get enough fuel.

tnx for the replies! This morning I checked some things, also the wastegate, which seemed to be stuck . There was a garage that was able to help with this, but before we went there the problem already seemed to be gone (strange because nothing was changed).

 

I had the wastegate made to move anyway, and also they cleaned the connector that connects the CPU to the valvehead since it was very oily and thats also supposed to be a common cause for similar problems. Head was removed, connector got a new seal, cleaned and head placed back

 

Seems to be running fine again! tnx for the videos, helpfull

You need to disconnect the connector quite often to get rid of oil. Change the internal cables under the rocker cover too. The oil in ECU connector comes from theese. Oil in the connector close to the ECU may fuck up the ecu.

I'll check that toon sometime soon

Injector harness is not too costy to replace, eg. this one or similar: https://www.bearmach.com/product/wiring-looms-elwrwrlo/fuel-injector-wiring-loom-suitable-for-defender-discovery-2-td5-vehicles-3-year-warrant-more-durable-then-standard-amr6103r/AMR6103R?locale=en
