can anyone help me out before i start stripping stuff off that i dont need to

If you do an advanced search for 'EGR' in the Doblo section there are quite a few threads on this subject.

Well i had a go at it today but i could not get a couple of the bolts out

I did manage to blank it off to check it is the egr that is causing the problem

and sure enough power had returned,i am going to try it again tomorrow.

I managed to get the stuborn bolts out today

stripped and cleaned the egr

all refitted and is now working fine

Thanks to the two guy`s that sent me the info

thanks again

im now having this problem only my stilo is undriveable i stalled it today and now it wont go over 20mp there was no engine light on at all i had a quick look at the maf and the and disconnected the egr tried to drive and still the same plugged the egr back in and now its saying engine fault and the engine light is staying on....... anyone any ideas as im pissed right off having no car and looking like its gonna cost hundreds

I've been having this hassle with a lack of power for about 2 months now. I have paid 3 different garages to diagnose the problem. I have fitted a new egr and have been quoted 140 for a new MAF. If this doesnt clear the fault where do i go next. Thanks for the info tho, good to know its not just me.

split pipe on wastegate

Just reading through this, i would suggest that the initial poster had the fault incorrectly diagnosed as an EGR valve fault will put up fault codes reguarding the mass air flow sensor and air temp sensor both open circuit which typically you would replace the maf sensor being both sensors are included within the maf

Also agree with T14086 about the split waste gate hose after having a few over boosting caused by the extreeme angle the vac hose runs between the actuator and solenoid, the vac pipe rips off at the actuator end on the turbo. Typically you will find if you hold the revs upto the limiter and it over boosts it will no longer allow you to rev above 3k and place the mil light onto the dash, leaving an over boost code in the system

high guys. have changed my mass sensor and egr but although power loss not as bad,still got miss in low revs and heavy smoke.is this a timing problem or maybe an injector?iam also getting warning that glow plugs are u s , could this have an effect?

helps telling us what engine/year your car is

my doblo is having problems with loss of power also.

its a 1.9 JTD . was driving along normally and all of a sudden the EM Light came on, with a noticable decrease in power, felt like the turbo wasnt working.

Left it to sit for an hour or so, and it took absoultely ages to get it to start, must have cranked the engine for about a minute before it fired up, when it ran the EM light wasnt on, but obviously there was a problem with it as it kept cutting out when i tried to pull off and put the engine under load. the engine would run fine on tickover.

T mentioned something about the wastegate pipe. any information on where this is to be found? pic would be nice if possible.

On another note if T does see this,
Before christmas i had a dodgy batch of biodiesel, i had to siphon it all out myself through the fuel filler using a siphon kit. I suspect that i may have damaged the fuel sender by doing this, as when i had drained the tank completely (ie. sucking air, and with ignition on can hear the fuel pump sucking air) the fuel guage showed 1/4 of a tank still. just wanted to know if the sender was anywhere near the fuel filler pipe, and if it could be damaged this way.

many thanks , Jon

I need to join this club my loss of power was as follows:-

Going up a steep hill on a motorway with pedal to the metal. Suddenly I lost power. No smoke, no funny noises just felt like the turbo had fallen off! Pulled off the motorway and noticed it runs perfectly except it seems like the turbo has vanished. Took it to a garage near me and they plugged in 2 different diagnostic systems and found no fault. They checked there was boost but didn't know how much a Doblo should have - so the turbo is running at least. They had a good look for split pipes, wires off sensors and could see nothing wrong. They suggested blanking off the EGR as test of a common problem but said it might be cheaper to take it to a Fiat dealer as they might be familiar with the fault.

Before I do that as I have a deep mistrust of main dealers any other suggestions? Does the Doblo turbo have a throttle? I seem to have boost at high revs, at around 3000 rpm but below that it's now gutless where it used to pull hardest. It drives more like a petrol with a very narrow rev range!

Thanks.

its a 1.9 jtd on a 2001 it has 105000 on the clock.when i unplug the mass its ok.could it be an air leak on the turbo pipes?

hi just sorted the problem,it was a slack jubilee clip on the pipe from air mass to turbo causing air flow loss.spent all that time and money on egr air mass ect only to find a loose pipe.just shows you these dealers really are no good at all!!

you made no mention of taking it to garage? did you pay?

Hi, everyone, I´m new at this forum.
I own a Doblo 1.9 jtd 105 horsepower, 2008. Wich a bougth brand new.
About a month ago, the engine ligth got on. And i felt loss of power in low rpm. just until 2000rpm, wich is when the turbo get´s on. I had someone with a computer to plug in the ECU, and it gaves two errors:

401 - EGR Valve
10F - Incongruençe MAF/debimeter (I hope it´s the correct translation, once it was in Portuguese)
Then he erased the errors of the ECU.

I have dismounted de EGR valve and the MAF, and cleaned it both, ( the EGR with oven foam, water, let it dry and finaly with breakes cleaner spray, and the Maf, only with the brakes cleaner spray). And it seems to be properly cleaned.
The results howver aren´t the expected,.... it still has the same problem, the only diferençe i have notest, is that the readings of the fuel cunsumption are much biger...
The engine ligth, stays of, but car still has no power...
Can someone help me, with this?
:bang: :bang: :bang:

When you cleaned the EGR was the spring loaded valve moving freely?
Cleaning the chamber is only part of the process, the valve as to move freely.
Last time I did one, I had the main chamber soaking in parafin for a week and still couldn't move the valve, even with a G clamp.
The electrical part was removed so as not to be contaminated with cleaning agents, then I soaked in an aggressive ink stripper for 5 minutes and that done the trick. Valve could move under normal finger pushing pressure. That gives an example of how hard to carbon stiffens.
Another option might be to temporarily blank the EGR valve and see if that makes a difference. If it does, you can do the read ups on here and do a perminent job.

Hi. Retro Pedro
The valve did move almost freely, but after the cleaning, it was moving quite ok.
I did, disassembled the valve from the electrical part, to clean it.
I did not tried to blank, the EGR yet. I´ll trie that this wekend.
Do you know if these problem, influençes the emissions, cause i must take the Doblo, to the periodical "legal" inspection. (i don´t know how to translate that to english, i live in Portugal).

In all honesty, I'm not sure what the effects of a blanked EGR valve does to the emissions. It is a subject that as been touched on this forum quite frequently. If you do a search (maybe google), I'm sure it will lead you to a relative thread.

egr should only work ( if working) until the engine is up to temperature at low revs, after going up to temp the valve should stay closed.

a blanked egr valve should make no difference to the emissions, a faulty egr will.
