Thread: Help Needed - diesel mechanic advice

Hey guys, I could really use some advice if anyone is a diesel mechanic with experience in modern common rail diesels...

The details are a bit long and boring to post but, long story short - I've paid a deposit on a 2014 Ranger but the guy has just txt me saying there's an injector fault... I've got a couple of options but need to know whether or not I carry on with the purchase or walk away and try get my deposit back.

If someone who knows stuff could spare me 5 minutes over the phone that would be greatly appreciated.

Cheers,
Adam

i only work on the electric side but whats the symptoms ?
unless its been abused i wouldnt expect injectors to fail this soon

My advice without knowing the details is Walk away! There are plenty of others out there.

All he's said is that the check engine light came on today. He took it to the garage and that they've said its an injector.

Bank on all of the injectors will need replacing, $5k+ if you get the dealer to do it.

How many KMs has it done?

It's a pretty good deal - not outrageously good but good enough I don't want to walk away without considering my options

Yes I can, but I need to decide if I'm walking away or making a "worst case" offer to go ahead with sale.

What I don't want to do is have him replace one injector and me buy it needing to do the other four plus the pump in a few months

@Tommy is this your skill set? Dorkus would know more if the Ranger had a rudder.

There might be something in here covering it. F/B Aussie 4WD Ranger PX

yep well our triton came up with "low turbo boost" on the diagnostic though in fact it was a jammed exhaust gas reticulation valve (due to crap nz diesel no doubt) took a couple of hours a few toothbrushes and a few pints of petrol to clean it. problem gone.
then i got serious and took inlet manifold off and scrubbed all that clean as full of gummy soot.
now i run a small electronic mod that convinces engine management its really cold outside no the egr switches off automatically. more economy, more power and less lag as a benefit

I just spoke to a really good diesel mechanic who clearly knows what's up. He suggested the first thing I do when I buy a ute is have the Ecu remapped to disable the egr, he says it makes a massive difference in power and fuel consumption as well as cutting down on injector issues.

He also said I should pull pin on this deal and get my deposit back - which I have done.

Bailing on it was the best idea, that could have been expensive. Everytime someone brings in a vehicle they've bought with existing faults like that it's been tears in my experience

Nothing wrong with a turbo on a solid engine like those.
Only thing kills them is backyard experts "turning the fuel up"
egt are the killer

All these new diesels require specialist tools only the dealer franchises have, mate of mine had toyota replace injectors etc in his hilux and as above no change left over from about 5 grand. I think common rail parts like injectors etc are due for replacement around 120-140k according to the maintenance programme in the book. I'd pass on it and find another one that may have had work already done on it. Plenty out there, Rangers are dime a dozen now.
