Anyone called Fiat Camper Assist for issue once home?

[heliart]

Had the engine check light come on this weekend on the way back from Wales. It's the common one with the exclamation/engine check and no start stop. I'm certain it's related to the AdBlue system as only just filled the tank (I topped it right off which I now understand can cause issues). Motorhome drives perfectly, and there's no code showing on my scanner for this one.
I've no local Fiat Professional dealer that can take a large motorhome, so I assume my only option is to call Fiat Assist.

Anyone had experience of having Fiat Assist come out to your home? Ideally, just need a Fiat engineer to read the codes to see what the next steps are.

Thanks,

Steve

I had Fiat Assist come to my home, I was pretty close so decided I could get home without a problem.
Now the point, the technician stuck his reader on and diagnosed I had one faulty Nox Sensor.
I asked for the read out and he e mailed it to me there and then. He cleared the fault although I had the option to just leave engine warning light on but I figured better to have it cleared.
I contacted Adams Morey at Portsmouth, sent them the e mail and arranged an appointment to have it replaced.
Went down there, a fair journey, I live in South Bucks.
The service manager was really apologetic, explained that the technician had cleared the fault and now no fault was showing on their system so he couldn’t fix a fault which was not showing.
I pointed out I had sent a full report from the technician who had attended, he explained that that person was not from Fiat and Fiat would only fix faults, under warranty, showing up on their system.
So the point, the technician who attends is not necessarily from Fiat and Fiat won’t accept what his device reads.
Don’t have the fault cleared because when you turn up at Fiat Professional, no fault showing, nothing they can do, fair enough.
Actually I guess the moral of this story applies whether Fiat Assist come to your house or not.
By the way the fault reappeared after about 3000 miles and Nox sensor and loom replaced under warranty. I was actually praying the fault code didn’t rectify itself!

I've had exactly the same experience week. Fiat Assist technician came to me when the engine warning light came in a d the engine went into limp mode. The van was recovered to a Fiat professional dealer who I trust and unfortunately as the FA technician had cleaned all the codes they can't read any data or find the fault. To be fair they have tried driving on short and long journeys and leaving for a couple of days parked up but the fault code won't appear.

Fiat won't let them replace the sensor even though the FA mobile technician diagnosed it as the problem, before clearing the fault codes.

 

[heliart]

Good advice. The van certainly did not go into limp mode, and based on some Google searching looks like there's a lot of problems related to the AdBlue system - easy to overfill, or block the breather and confuse the level sensor. No idea here though.
I called them just an hour ago, the vans on my drive, ETA 4pm. Will keep you posted.

This happened to me, not with FIAT but with my Volvo V60 in 2017.

When they changed the engine in 2015 to 4 cyl D3/D4 they used a EGR cooler and no ad blue, which then chocked up and needed a modification. Engine management light came on so booked in to dealer, they ordered the part and rebooked me in for a week later.
Then they phoned and said because they had cleared the code the week before they couldnt do the work because there was no fault code.
Couldnt make it up.
They started to use ad blue in 2017

I made the point that surely the sophisticated engine management system which recorded faults so efficiently must have had a memory. Apparently not.

Chap from Fiat Breakdown just been out. Took a bit of effort to get the OBD unlocked, but was finally able to confirm a P2044 Exhaust gas temperature sensor - Signal low. Not able to clear it, so it's an active error.
They will come back to me with a list of local Fiat Pro dealers who could take it, but my preference is Adams Morley in Portsmouth. I'll give them a call tomorrow and ask for advice.

I think that’s what I had, if the temperature does not get up to the required temp it can’t do the reading. A new sensor plus wiring loom in my case.
I found it quite amusing, Fiat Professional in Turkey just told me to drive it all the way to the UK, wouldn’t be a problem even with the light on! A second Fiat Professional confirmed that as well.
They couldn’t answer my question “ why put it on if it made no difference”

 

[heliart]

Well, based on the diags, it was easy to to a check of the wiring just to make sure it was nothing daft.
I find this. What do we think, rodent damage?
I do find it hard to imagine where or when this happened though.

It certainly looks like something has chewed it. It doesn’t look as if it has frayed by rubbing against something and surely it cannot be wear.
The problem you face is the likelihood that Fiat will claim it is an issue outside of the warranty.

I am inclined to disagree in that by the marks to the left of the cable, it looks as though that cable has moved location at least twice. The insulation is possibly supposed to be crimp cleated into the top of the sensor. The top of the insulation is a clean cut albeit oblique but no sign of nearby tooth marks. My guess is that it was poorly stripped so the insulation was not at 90 degrees to the wire so the cleating could not hold as the insulation was not completely within the crimp area.

Indeed, I've just ordered a new sensor (£30), so will cancel the claim. But, it's annoying having to call out recovery just to run the diags to narrow down the issue as Fiat lock their OBD. I really dislike that manufactures make it so difficult to do any type of repair.

This is like a forensic analysis.
I’ll suggest another scenario.
The actual sensor is threaded, could it be that unless the wiring loom was disconnected at the other end, when the sensor was moved at some time in the past, the twisting resulted in the damage at the weakest, previously crimped point?
Motorhomefun at its best on a miserable day!
Incidentally my understanding of the fault I had was not the actual sensor but damp had got in at the “Electroblock” connection so that part of the loom was replaced including the sensor itself.
That connection is clearly to be seen, open to all the spray etc coming up underneath the vehicle. I questioned why the designers didn’t think to have it shielded or indeed put it in the engine compartment.

Could be, but there are a few other scenario's that fit the 'forensic evidence'. However many, many years of crimped cleats. especially with multicore and coaxial cables where the insulation layer is relied upon to hold the cable in position has shown me time and time again that its a poor method unless a rigid sleeve is inserted between insulation and core(s).

Have often wondered that in several vehicles.
