Hi all,
Just sharing some good news -
I purchased a secondhand hilux recently with the D4D engine, thought all was good until I started it up on cold mornings. The thing sounded like it was about to explode until up to temperature. So off I went researching and eventually resigned myself to the fact that it needed $3.5k spent on it for new injectors.
Called a couple of places and finally also called Toyota as the thing needed its 200k service anyway, mentioned the issue and the service manager said he would check if the VIN had any history against it. He found that it had never been back to Toyota and hence missed out on an ECU update.
So I spent $80 for them to check the injectors % and do the flash update. Turns out the injectors were OK and they said just drive it for 1000kms for the flash to work.
1000kms later the thing runs and sounds perfect now. STOKED. So hopefully this enough of a fix for others too, (I had never read this on the net).
Now I just need to deal with the billycart suspension on this thing :O
Cheers, Tim
