Any Diesel engine specialists?

[Nasher]

Help.
Just as I’m saving up because my contract is coming to an end my car starts playing up.
It’s a 3.2l TD Mitsubishi Shogun with 98K on the clock, manual box.
I don’t have enough experience of big diesels to make an educated guess at this one.

I’ve noticed recently that sometimes, not always, its not as gutsy as usual, and often its got no power under 2000 revs at all, which is when the Turbo cuts in and gets it going. I thought it was just in need of its regular service so I’ve changed the air filter, fuel filter and done an oil change without making it any better.

This morning in the cold it was worse than ever. Until it warmed up slightly it actually struggled to make 2000 revs in the first place, and even when warm was completely gutless under 2000revs. It was quite dangerous pulling out onto roundabouts when it bogged down.

I’m thinking it might not be getting enough fuel for some reason.

Anyone know of a reasonably priced Diesel specialist in or around Pompey?

Is it fly-by-wire throttle?

Does it knock at all when it's doing it?
It almost sounds like a computer fault.

Do you have starting problems?

Could be all sorts, but after doing research on Delica diesels a year ago I have discovered that one of the most common problems for poor running is air in the fuel system or turbo charger problems.

Post your problem here or do a search Nasher.

Hi, its a standard cable type throttle.
It doesn't knock, its just completly flat then picks up.
Runs on slightly when turned off too strangely.
Starts first time even when cold.
Its also getting worse rapidly.

I've just been round to a diesel engine specialist round the corner from work who can have a quick look tomorrow.
He did say that his equipment struggles to talk to Mitsubishis, but both the new shape Shoguns he's worked on recently needed new fuel pumps!


Sounds expensive.

I would check all your hoses first. My work had a Mondeo Diesel that they sold off for £200 spares or repairs because of lack of power. All it was, was a hose that had fallen off and no one had seen. Might also be worth looking at the hose to the turbo. Another common problem is that the Turbo unit has some form of actuator (something to do with the waste gate) these can corrode and need freeing or replacing. EGR valve is another Mitsubishi weak point......The list goes on.

Have a look on the forum. I'm sure it'll give you other Ideas to look for.

Thanks Andy

I'll have a look later.

Sounds like the fuel pump seals.

Have a look here.......

Come on Dave, get with the program. That's what I said several posts ago

Are you still suffering from Sea Sickness from that "circumnavigation" .

[Nasher]

David, Andy

Thank you, I was aware of the pump seals issue on the older 2.8 engine, but believe its been sorted on the 3.2.

I used to use the POC forum all the time when I had the 2.8, but they didn't really cater so much for the newer vehicles, so don't go near it often now.

Sorry Andy but with all the twaddle you've posted in the past, I've got you on my ignore list so I don't see your posts.

Thank you....Hook, line and sinker

Another note of caution re. main dealers. My L200 developed a prob where it would start fine when cold, but not when warm unless left to cool down. Took to be diagnosed at the Mitzy dealers, they were on the blower to say that the pump was F'd and that they required a grand to put it right, would I like to go ahead? I grabbed it back and paid the £67 diagnosis fee. Took it to the local Bosch guys, £219 later and a new anti-theft device on the back of the pump and it was perfect. I rang the service manager at the Dales Mitsubishi, Summercourt, Cornwall. His response was ' Well, you've had a result'! Should've demanded my £67 back.

I've had similar experiances with Mitsubishi dealers, and will never go near one again. If I ever get another job it'll be a Landcruiser next time.
Interestingly, the guys that will look at it tomorrow are the local Bosch guys, a place called Powerdrive in Portsmouth. £45 diagnostic fee.

An update.

Apparently the local Diesel experts could not ‘Talk’ to my car with their equipment, but as they do a lot of work for the local Mitsubishi dealer, the Mitsubishi dealer has run the diagnostics for them and found several fault codes all leading back to a faulty EGR valve, annoyingly it had a new one fitted under warranty when I first had it 3 years ago.

They have stripped it out to try cleaning it, but its not working electrically, I presume the solenoid is knackered.

On the old 2.8s the EGR valve can be blocked off or even replaced for about £35, but of course being the 3.2 I need to replace it, stump up about £250, and wait until Friday when they can get one.

Biggest annoyance is the chance of Snow tonight and not having the car to play with, particularly as I live on a very steep hill and often have to tow the wife’s Pug 206 up the hill in the morning when it snows.

Oh well.

Don't worry Nasher, I haven't got my 4x4 either. The heater matrix sprung a leak last week and I'm having another one fitted (hopefully). Looks like BIG £££'s also as the dash has come out .
