Rodeo 3ltr Common Rail - What good are modern Computer Diagnostics?

Tony.
The diagnostic system relies on data from the sensors around the vehicle, if the wiring or connectors get water or mud in them the readings can be wrong. I suggest you get under and have a look for water in any plugs or wiring, if you find any clean the component and give it a blast of WD40, the plug under the fuel filter would be my first spot to check.

Sadly, these days you get only what the manufacturer thinks what you should have, not what you want.

This year I went fishing in the gulf with a mate who has a 2yr. old Rodeo trayback. My impression (my turn to drive) was yes, towing the boat, plenty of gear and fuel on board it went very well on the bitumen.

Come to the road E of Borroloola it was a fair pig of a thing, nothing off boost then along comes the turbo and wheelspin everywhere.
Then the fun starts, lights on the dash, engine goes off song, wont go into 4wd. get into 4wd after stalling in the first river crossing, then wont disengage 4wd. Push buttons and lights on the dash, would you believe.

After a very annoying bogging session (old 60 series cruised through) the mate said if it is in 4wd, then its going to stay there.
And it stayed in 4wd until we got back to the Barkly homestead. ( several 100k. of bitumen!)

These things are supposed to be agriculturally orientated and user friendly as a minimum. Not running back and forth to the dealer.

Hi Tony, I have a 2005 Rodeo TD and had a similar problem on my last trip. After a while cruising at 100kmh the "Check Engine" light would come on, While the light was on I could not accelerate above 100kmh so I eased off to 95kmh & after about 30 seconds the engine light went off...but everytime I got to 100 again the light would come on.

I took it to Longreach Holden and they checked it out and said it was the EGR Valve, they replaced it for me at a cost of $375 and I have had no problems with it since (I thought the price was reasonable seeing as we were only three days into a 12,750 km trip).

They said with the old valve not working properly there was a build up of exhaust gasses that the valve could not handle at 100 kmh, when I slowed down the gasses were processed properly.

Regards, John

I've been closely following Rodeos and by all accounts some have sworn by replacing the wiring to the 4x4 buttons with a heavier gauge. 3rd hand stuff but there you go. not that this is an answer to ERG valves but a possible solution to other issues.
