Technical Marea weekend 2.4td does not like hills

Sorry for not replying sooner been out of the country!

The boost control valve is in the center of he engine bay just under the windscreen! should have 2 black pipes going into it!

I also had the same problem on my integrale!

Could be a number of problems. Egr vavle sticking or solonoid not working correctly. No 1 injector faulty(With Pickup), Timing out( But Cant See It), Turbo Waste Gate Ceased, Air flow meter Faulty,
 
Now i have the same problem, driving at around 3000revs and foot down, nothing, clutch in rev below 1000 and clutch out foot down and its ok again, just changed the fuel filter and sorted one problem now got another, so i'll have a go at the air flow meter, i take it this is near the air filter
 
Sorry I have not posted for a while, I would hold off on replacing the air flow sensor as it did not fix my problem. I have had a electrical guy looking at it and he is baffled too and there are no error codes stored but I can now describe the problem better after playing about when it comes on.

It has nothing to do with hills it is just more obviouse when going up a hill. It works fine when you pull away or constantly accellerating but when you hold a constant speed after a short while the problem comes on, you can sometimes feel it happen, then when you accellerate there is nothing untill you dip the clutch. Speaking to my mate who is into turbos he say's that what you are holding a constant speed the turbo power is cut for fuel economy but it should kick back in when you accelerate which it does not appear to be doing. I was wondering if this could be due to the waste gate / actuator or any other part of the turbo system. I will be getting a boost gauge in the next few days to see what the turbo is doing, but in the mean time if anyone else has any other idea's what what it could be or what to test I would be most gratefull.
 
I bought a Marea weekend recently,a 1.9 jtd It was useless on hills could not pull a trailer and would not pick up speed till over 3000 revs. I was told by Fiat it needed a new mass meter. I had a full service new mass meter,new cam belt,timing re set. £800 later the rear wiper motor has failed the airbag light has come on and it is still no better at pulling. Fiat say there is a loss of pressure but seem baffled. I have been told it may be the "Waingate" on the turbo.
The cost of parts and labour are horrific I could have bought a new car by the time I finish. Any advice on second hand parts would be appreciated.
 
We've had the same problem on our 2.4TD... I've kind of gotten used to letting the revs drop down every time I change gear to keep the turbo around... We took ours to fiat and they said that there was a fault on the ecu and they wanted £1200 to fit a new one!!!
I think I'll stick to the clutch peddle jiggle!

Just a general tip for all you diesel chaps losing power:

looking at the diagrams in my workshop manual it looks like the older 125TD's use the airflow meter - big cast aluminium box thingy near the radiator...
but the 130JTD's use the air mass meters -black plastic tube with connector on side
My father in law has got a diesel in his ford people carrier... his air mass meter broke and when he got it fixed there was a huge pile of them at the garage that had broken recently...

The point is that they look like a generic part that is used in many engines the one on his car is the same as the Volvo, VW etc...

So if you have to replace yours, and it appears a common fault, shop around don't just go to FIAT...

He was quoted between £200 and £90 for the same unit at different places - apparently for different cars but same part number on the unit!
 
I have the same problem with my marea 2.4 td. driving at around 3000revs and foot down, nothing, clutch in rev below 1000 and clutch out foot down and its ok again, please help.

I know you are not going to believe this suggested solution but here goes. I'm non-technical so forgive my description. I had the same low power problem especially on hills. I took it to my local garage and he was completely mystified. He then took it to the Fiat main dealer and tested the management system. The Fiat guy said it could be a problem with what I was told was an air flow meter, but which sounds like the Air Mass meter described above. It is a black plastic box with a channel through the middle of it. Apparaently the contacts within can get coated with carbon ( I think). The Fiat guy said we could buy a new one at £200 or we could take the old one and boil it for 30 minutes in an old saucepan. My garage guy thought that he was trying it on, but was reassured that it would probably work. I agreed to give it a go and hey presto when it was plugged back in full power was restored. Hard to believe but true. No problems since it was done last March. Let me know if it works for you! :)
 
Are you sure that you talk about fiat marea 2.4 td (91 kw), On my marea box is gray with black plastic cover. I have open this box and tray clean, but is usselles. When sensor is disconnect, then evreything is ok, but car is lossed on power, not much but is lossed. In my country new parts costs about 600 $. I am not yet sure that is problem with this sensor.
Sorry on mistake with english language.
 
looking through this post and didnt see anywhere. where u said u change the fuel filter but i take it u did??? it sould like fuel if the car only does on under pull also check the air filter if it is dirty it can cause a loss of power
 
Now I have get air flow meter, not new, used from kappa 2.4 td, beacouse this car have the same engine like my marea.
I' ve been looking original part, but I did not find him.
My friend have finded him only from Lancia kappa 2.4 td, in GRAZ (Austria), used sensor for 100 eur.
I have changed sensors ( I think that the parts are the same, only different is that my sensor is BOSCH 028 1002 185, sensor from kappa is BOSCH 028 1002 285, same look and same conector) but problem has stayed.
When I driving constantly and press acceleration pedel, nothing has happen, so I must press clutch and release pedal to get 1000 rpm.
After that everything is back to normal.
I have taken car to FIAT service, and they said to me that problem is in ECU unit (computer has writed ECU ERROR), but they not 100% sure that is problem in this.
They also said to me that ECU unit is very expensive.

I've got the same problem...

Just have to do the clutch shuffle each time the turbo stops working... :( FIAT quoted me £1800 to fit a new ECU...
 
Has anybody who has suffered this problem managed to successfully fix it? I bought a 1997 TD125 yesterday and it has the same problem!

When I was collecting the car yesterday, I was doing 55mph on the M62, foot to the floor in 4th! Not only was this very embarrasing, but imagine how bad I felt having forked out £850 for a car 10 minutes earlier that can't even do 60 mph!

The clutch dipping trick is how I am able to temporarily regain engine power.

I don't think its anything to do with the turbo because surely even if the turbo stopped working, the engine would still have enough power to make the car accelerate (all be it, much more slowly) whereas the problem is that the car will not accelerate at all.

I'll try the above suggestions and report back after I've test driven it.

Yes, i have findit solution. This marea 2.4 td not working o.k., if egr valve is not working. I have changed boost control valve pipe and now everything is normal. Try to see, is it egr valve working.
 
Is this an expensive job to have done at a garage in the UK? My mechanical knowledge is not great.
 
I don't now. I think that is not expensive. The same control valve have all 2.4 jtd ant td motors. Just try to see, when engine is turn on, remove out pipe (pipe is going to egr valve) from electro-valve. On your finger try to feel vacuum (who turn on egr). Electro-valve is in center of he engine bay just under the windscreen.
