I've had an EML light on for some time now. Local garage cleared it for me and said there was a pressure differential in the DPF showing up as an error. After the car was serviced on Saturday, I drove about 10 miles and the car went into limp mode (how annoying and dangerous is THAT!!)
I took it into a Fiat dealership service centre on Monday and they were going to see if they had a new sensor (where the local garage said the fault lay) but one of the service guys came out with the front desk man and asked if he could see the car. He said the sensor was usually a Ducato issue and on the smaller vans it was the hoses that were at fault (sounds like a Fiat undisclosed admission eh?)
He went straight for the right front side of the engine and said yes it was the hose. I couldn't see it a I wasn't sure where he was pointing but they ordered the new parts and it's in Thursday for fitting (2 hours). In time, looking at home, I found the failed hose
Here are 3 pics to try and give the location but you can see the split quite clearly. Pics taken in the garage with a torch - sorry they're not very bright..
If you locate the DPF sensor on the firewall about 2/3rds of the way across and just below the bonnet seal, it has two pipes going down from it in braid which then connect to two metal pipes and go across to the engine. They then become braided rubber pipes again going round the front of the engine (for flexibility I guess) but they are too short for such thick pipes and such an acute bend. In the heat environment and the hot/cold/hot/cold of vehicle use plus engine flexing, they fatigue and break throwing an error code and causing the dangerous limp mode (1500 rpm in this case)
It's a known fault to Fiat but not subject to a recall (AFAIK) and one only learns of it when you get an error and subsequently the limp mode.
I recommend you look for these hoses and check to see their condition. You have to peer quite hard, they're under a thin flexi-cable conduit but you can trace them back from the exhaust downpipe - two metal pipes come out from the RH side and go across to the right front of the engine - there's where they change to rubber braided hoses, (going backwards to the firewall and sensor unit) and that is the place they break. Mine began with problems around 34,000 miles
HTH.
