power loss on hills

[dandywarhol]

[edited] Ok. i've exhausted all the decent garages in my local area, and they've all given up.

All I have to show for it is some diagnostics .

When the engine gets warm after about 10 minutes
the glow plug starts flashing and the ECU diables the turbo as
part of a 'limp-home -mode'

The first 2 error codes given to me by the first garage
(which were 'wastegate' and boost pressure valve')
appear to be either spurious, or merely indicative of the fact the vehical was in safe mode.

The new diagnostics specialist says that 3 error codes appear similtaneously
with the flashing glowplug light, and the disabling of the turbo.

1) air intake temperature sensor (presumably the scavenger fan one near the handbrake - swapped this out)
AIT is the temperature of the air in the intake system (as the defination implies) NOT the scavenger fan sensor)
2) accelerator pedal (?)
This sounds like a throttle potentiometer - makes sense as the pump is "fly by wire"
3) diesel pump pressure sensor (?)
As it implies?

Fuel pump is electronic - the injectors are as standard older design.

I'd be inclined to have the codes erased, now you've logged them, and drive it again to log more fault codes

I'm going to try swapping the coolent temperature sensor and see if that helps.

can any one point me in the direction of the correct sensor and show me where it goes?

I've tracked down the one pin temperature sensor and the two pin sensor but I'm not sure which one
i need.Is this the one that goes into the engine block on the drivers side?

[dandywarhol]

2 pin

[berrega]

1) air intake temperature sensor (presumably the scavenger fan one near the handbrake - swapped this out)
AIT is the temperature of the air in the intake system (as the defination implies) NOT the scavenger fan sensor)

Please forgive me my confusion.

The sensor show here
http://www.gumtree.com/london/57/52998157.html
is described at the IAT sensor.

This looks identical to the one that I purchased, to swap out with the sensor by the hand brake.(scavenger fans sensor?)

So does this mean that it is the same sensor used in multiple locations?

and that I just need to find the location of the Bongos IAT sensor so I can test that one too, with the one I have already purchased?

[dandywarhol]

Ah - ok, a post a few weeks ago suggested they were the same sensor

Why not look in Lushprojects for your model?

Hi

Think you'll find it's the L/H Solenoid on the bank of 4 on the drivers chassis leg under the drivers seat,this is the one that controls the EGR Flow,that in turns supplies the acuator it's vacuum.It's the Black one,I know all 4 are black,but the other's have a coloured spot,1 x Blue,1 x Red and 1 x White,If I remember correctly it should operate at about 8 Ohms,mine was drawing 37 Ohms !

The Fault codes should be P1228 Mazda Wastegate Failed Open (Under pressure)

P0400 Generic Exhaust Gas Recirculation Flow

Hope this Helps

[berrega]

Do you know where I can get one from?
Do you have a photo, or which page they are on in lushprojects or part number?

I think I may have found the component you are on about.
there are 3 solenoids with a white, blue and red dot on, then one on its own that looks differnt with a green
plug. (K5T49091 KL01 6Z19) I'll get a photo.
Is this what you are talking about?

I'll add it to ther long list of possibilities I'm steadily working through.

To be honest I'm emotionally drained.
I never would have bought a vehical if I knew that if something went wrong no one would now how to fix it.

It occurs to me that only mechanically minded people should own Bongos and I'm not.
I'm getting close to the point to taking the fanancial hit and just trying to selling as faulty.

Theres enough stress in life without driving a vehical in limp mode none stop which flashes a yellow light at you constantly...

berrega - has the Bongo yet been to see a proper Bongo specialist? regretfully, I think it needs to before you throw in the towel. What about starting by speaking with people like (taking closest I can think of first) LPG Imports in West Mids (they seem to know their stuff though have only recently come on our radar scopes - but I'm sure they will tell you straight if they feel its beyound them). Then there's Ian Taylor in Market Drayton - v. experienced with Bongos and an excellent reputation. Then Wheelquick in Wigan.

The money you've already spent has I fear to be written off (though if the eventual cuase is found to be something else then the original garage ought to feel a bit ashamed). But if you sell now, you probably stand to lose out over what you might get (assuming it is a nice example in other respects) once its running properly.

Can the old girl be persuaded to drive to the above locations if need be? Or else maybe your breakdown cover could be used to get you there?

Good luck. Its a bummer, but thats cars I guess (nightmares in waiting).

I really feel for you, as it really is one thing after another at the moment not to mention the expense.

How long have you had the Bongo and where did you buy it? Did it come with a warranty of any description? If purchased privately, do you have any suspicion that the previous owner wanted rid because it already had problems. Don't know if there would be anything you could do if it were the latter as you would need to prove it.

I know nothing about mechanical things, or worse electrical/computer things but I'm wondering if you need a new ECU? This has probably been suggested already (I have been following your posts but can't remember everything ). I suggest this because Dandy mentioned the potentiometer earlier. I had a Fiat Multipla and although it had a manual gearbox it was a diesel and at just 1800 miles (during its warranty period) it exhibited a variety of symptoms which pointed to fuel starvation - loss of power and some cases cutting out at speed (ie at 50 or 60mph on the dual carriage way). I had three new potentiometers fitted before the Fiat dealer (who should know their stuff) put a new ECU in. After a further replacement ECU and a fourth potentiometer together with new injectors, the problem disappeared, never to return again. It was off the road for a total of 7 weeks (2 x 2 weeks plus 3 x 1 weeks) and a total nightmare.

As I say, just a thought, as your Bongo's symptoms differ (and my problems weren't on a Bongo anyway) but it was definitely a "mystery illness" fixed by trial and error.

[berrega]

How long have you had the Bongo and where did you buy it?

5 months, Bongomania in Hucknall

Did it come with a warranty of any description?

1 month

If purchased privately, do you have any suspicion that the previous owner wanted rid because it already had problems.

They just ship them over from Japan, convert them to camper vans, and sell them.
I doubt thet had the vehical long enough to become aware of any problems.
The problems started just after the warranty ran out (typical)

These things tend to be a huge gamble. I gambled and lost.
I suspect it was the origional japanese owners who new there was a problem and got rid.

After all the banjo filter is missing, so someone down the line has removed it suspecting fuel starvation...

Berrega - follow the man's info!

[berrega]

Right. Ok. Done.

Can you conferm that the L/H solenoid

which I have down as the part number K5T49091 KL01 6Z19

is the same as the

Ford probe Mazda Mx6 626 Manifold VRIS Solenoids V6 2.5
K5T49091

[kozikot]

Think you'll find the newer fly by wire pumps dont have the filter or spring under the Banjo.....

Do you have a photo, or which page they are on in lushprojects or part number?

Think you'll find all the one's on lushprojects are petrol models,can't find any SGL's.....

One of the company's on e.bay were selling them as Bongo Air Valves That's how common the fault is on later SGL's

Will get you Part No + Pic Tomorrow evening

[berrega]

I think I've got it?

[edit]

Oh yes. Bongo Air valve.

http://www.japautosolutions.com/cgi-bin ... 3a527#a527

Looks the same as the one I've ordered.

[kozikot]

Looks like one,but they draw different ohms to operate, Most cars have them,the black plug is removable and underneath is another outlet,so they all look the same,some are 2 way,some 3 way and some are 4 way,but you need the right one to open at the set signal sent by the ECU,or you could put a resistor in the wiring to set the right ohm input.

The one's on Bongo's are Mitsubishi one's........

Can get you Pic and Part No for the one I'm talking about about.......

There's is Another one a Brown one on the passenger chassis leg this one is a Mazda one,that one receives it's vac from the one I'm on about,follow the vac pipe from the brown one round the front of the cam cover,into the metal vac pipe,then on from the side of the pump to the 2 of the 3 black solenoids which in turn are feed by the one I'm talking about.
