(T) DOBLO 1.3 2004 loss of power

Hi all and Happy New Year.
I am looking for advice on what could be the problem with my Doblo. Was working fine until a week ago when the snow came and then the engine light came on and now it feels like there is not enough diesel getting to the engine when pulling away in 1st 2nd 3rd gear etc.The engine is real sluggish. Its ok when i get it up into 5th buit getting there is a real struglle. Plus MPG is down in the low 40's when normally it was at 51 ish.
I checked out some of the threads on this forum and EGR and MAF problems keep cropping up, so i disconnected the sensor to the EGR and the engine seemd to work ok for a short while until i stopped to get diesel and then when i started up again the problem returned.
Anyone else had the same problems?
Appologies if this has already been discussed.
Any help greatly appreciated.

Likely to be the MAF, the cold seems to get them.

Thanks for the reply Ivantate.
If i was to remove the connecting cable from the MAF sensor and test drive the car and the problem was still present would this suggest the problem is the MAF? Would this test be sufficient or do i need to remove the MAF sensor altogether?

Thank again

Hi All, The AA came out today and diagnosed a problem with the Turbo Boost Sensor. fault code PO238.Is this easy to change out for the diyer?As usual any help/advice much appreciated.CheersMoremeba

It might be seized into the turbo, I think it might be easier to try and remove it when the turbo is warm.

(usually you heat a bolt to loosen it so the same should apply.)

Thanks ivantate. do you have any idea where i can locate the turbo and this sensor in the engine bay? What the sensor looks like etc?

Cheers

Hi moremeba, did you have any joy with your problem? I have 1.3 multijet on a 55 plate same problem. Code 0238 comes up ( Intermittent) and 0106 (Present) . My vehicle has no turbo!!

Hi Truey, i still have the same problem despite spending £300 at the garage. They changed the MAP sensor and MAF sensor because thats what their diagnostic kit came back with. This cleared the engine light for a day or so but the car still ran really rough and the MPG was down by about 10 MPG. The car has been back in 3 times now and each time the fault clears for a day or so and then comes back.
It feels like the turbo is not working at full strength, and occasionaly it will be ok for a few miles and then back to lower power.
I was hoping one of the gurus on here would be able to tell me where to find the turbo boost sensor and how easy/hard it is to change.
The garage and me are both loosing patience with each other and i am going round in circles, they say its the MAF/MAP sensor problem showing up on their computer and each time they reset it it clears.
My suggestion to you would be to chnage the turbo boost sensor first, i doubt very much there was a fault on my MAP/MAF sensor in the first place.

Any help advice regarding the turbo boost sensor greatly received.

hi mate my panda had same sort of problem got it sorted by putting WD40 on cpu connectors first take em off (the little box) then get some electrical cleaner,blast it with that, leave to dry then a shot of WD stick em back,while your there take off maf unit give that a blast with cleaner( not WD40) give all leads a good blast of cleaner i took off all injector plugs as well and gave them a blast then WD total cost under a tenner,,,,just give it a go before you take anywhere near a garage again...

Was just about to say the same thing, lots of Pandas with intermittent MAF problem just need some wd40 in the engine ecu connectors. The 2 big ones to the right of the engine.

Depending on the experience of the garage, the fault code can be interpreted in different ways. a MAF / MAP error can point to faulty sensors, but the error's are generated by being out of parameter's. More often than not they can point towards EGR fault's with the valve being stuck open/closed with out producing he typical p0401 codes etc for egr. Depending on the code description also, the 1300's can suffer with sticking actuators producing an over boost which will instantly put your MIL on and put the vehicle into limp mode to stop it occuring again

If you can post up the full code(s) and descriptions

I have recently had my turbo pressure sensor replaced (2004 1.3 Panda, but the same engine as far as i know). I didn't do it myself, but the garage (main dealer) i go to lets you sit and watch as they do it.
They took the air filter housing off and then it was between the back of the engine and the bulkhead between the back of the engine and cockpit. The mechanic had a bit of a whinge that you needed tiny fingers to get into the gap. Nevertheless, it only took 45mins to diagnose, fit and test, the part was in stock and it cost a total of 70euros, so the part itself can't be too pricey if you fit it yourself.
My symptoms had been engine light on and loss of power/limp home mode coming on.

or he had giant hands! my hands are big and its easily to change the sensor as only 1 x torx 25 screw.
