Isuzu D-Max Problems

No, yours doesn’t have a DPF filter. The D-Max is generally reliable with no major issues to be concerned about.

What they were referring to is the automatic burn of the Diesel Particulate Filter (DPF), which collects carbon in the exhaust while you are driving along, and then periodically goes through a cleaning process in which the accumulated carbon is burnt off. The burn-off happens automatically without you knowing it’s happening, but it needs regular freeway type driving for it to happen. If your travels don’t involve any freeway travel then the burn-off might not happen and you have to take it to a dealer to have it done manually. From what you tell us about your driving I would say it doesn’t suit a diesel, and you would be better off buying a car with a small petrol engine.

It could be a fuel supply problem, so I would suggest checking the fuel pump.

There’s clearly something wrong with it. Take it to a dealer and have it diagnosed.

It’s true that diesels are at their best on longer trips when they are fully warmed up and not accelerating and decelerating all the time. You can have problems with the DPF clogging up and not regenerating if the car isn’t getting up to speed for any length of time. You could take it for a run on a highway or freeway once a month or so to get fully up to working temperature, so the DPF burn-off car hopefully happen. If the burn-off doesn’t happen automatically you face the prospect of having to have the dealer do it manually, and that would involve a cost.

We haven’t had anything reported to us about cracking of the inner guard, but like you have seen reports of cracking on the D-Max. That suggests it could also affect the MUX.

Because of the modifications you have made, and the off-roading you have done, I doubt you would have any success if you were to make a claim against Isuzu for repairs.

While all second-generation Isuzu D-Max pick-ups ride on a 3095mm wheelbase the other dimensions differ depending on the specification ordered. The single cab is 5215mm long while the dual cab is 5295mm in length. Widths range from 1775mm to 1860mm, and height ranges from 1690mm to 1785mm depending if you choose a 4x2, 4x4, single cab, space cab or dual cab.

The ADR requires carmakers to have a side indicator so there is always a visible turn signal light, so you should be able to see that even if you can’t see the front light.

The idle is too slow to maintain running, so check and clean the airflow sensor in the intake, and replace the air filter.

Don’t mess about fit another EGR valve.
