Fiat Doblo Engine Trouble

[Mark A]

There may be a valve (electrical\vacuum) that controls the turbo - there certainly is on all VAG cars. If this starts to fail - then the car will go into limp mode and someone who isn't familiar with them would just suspect that there is an issue with either the turbo or its wastegate - when in reality it's a readily replaceable valve, with a few vaccum connections and a electrical multiplug.

Is the local garage a Fiat specialist or just general type place?

Do you know what the fault codes were?

The garage was just a local one and they didn't show us the fault codes so we'll take it to the local Fiat specialist next week for a second opinion. Its fine to drive, just not over 60mph :roll:

Thanks,
Mark

Hi everyone

We've had our 57 reg Doblo 1.3 diesel for about 6 months now and it's been fine until last night. I was driving at around 55 mph in 4th gear then felt a slight jolt and a big drop in power. It wouldn't rev past 3000, even in 2nd and 3rd and struggled to to 40mph. The engine management light came on then as well.

Strangely it improved by the time I got home, but the engine management light didn't go out. I drove it again this morning to test it and its running fine, but the light is still on.

I've done a quick google search and some people say its the turbo, while others say the injectors (hope it isn't - our Fiat Scudo was plagued by faults with the common rail, costing about £1400 in total over 2 years)

Any ideas what it could be, and what to do about it?

Thanks,
Mark

Hello

Yes, it turned out to be the Exhaust Gas Recirculation Sensor after all. The mechanic who replaced the sensor (the part cost around £30 I believe) said the old one was clogged with soot and dirt, causing it to malfunction.

I hope you can fix the problem!

Cheers,
Mark

I've got a Fiat Multipla 1900cc diesel. I too had a dramatic loss of power/limp mode and some jumped up box shifter was only capable of reading the error code on his laptop and calmly telling me "new turbo mate, £1200 and the fitting".

Me ol' mate John, he of ChickenShack Engineering fame, the dirtiest, most asthmatic wrench monkey I've ever met, looked at me like I had two heads when I recounted this. He calmly brought out a dentist's mirror(!!) and with it, read the part number of the sensor in the depths of the engine; had it ordered and fitted 24 hours later. Cost? £28, including John swearing blue murder as an Italian designer bracket caught his knuckles. Give me a PROPER apprenticed mechanic anyday.
