my d4d dble cab loses power under load(steep up hills/light towing etc)2nd gear needed to get up some hills.similar bakkies towing huge boats fly past!!have complained about the problem (toyota services) and have been told all is ok.the vehicle is now due for 90k service,i have an extended service plan on the bakkie ,so i'm obliged to use the agents.any ideas/advice?

Sounds like a dirty diesel filter, the agents don't replace them at service intervals.

I had the same problem a few weeks ago. Had no power and uphillsi was overtaken by corsa bakkies. Checked everything untill out of desperattion changed the fuel filter, problem solved.

ant,i change the fuel filter my self every 10k as the dealers wont,only use 50ppm fuel,do you think it could still be the filter

There are numerous things that could cause the problem. Check or get checked the following:
1. injector leak off checked
2. EGR (exhaust gas recirculation) valve. This should shut off under load and if it sticks open you loose exhaust gas energy through the turbo thereby loosing boost
3. MAF (mass air flow) sensor
4. Diesel particulate filter

The above items usually become defective with bad servicing or high mileage but from what I see you look after your van. Good luck...

Maybe just check it, I also change my filter frequently and somewhere I filled up at a place that had contaminated diesel, the filter was pitch black and with a lot of dirt in the filter canister. That was just a few weeks after my previous service. So just check it. If its not the filter then I'm clueless.

bakkie back from service,pulling well

,turned out to be the fuel filter after all(thought that replacing filter every 10000km would have prevented this!)must have put in contaminated fuel somewhere :? is there only one filter on the fuel line or is there another hiden somewhere??
