I took my Ulysse Eleganza to the local Fiat garage, as I was getting the engine anti-pollution system faulty error message and the car would go into limp mode.

They ran a diagnostic check and concluded that my fuel sensor cap and diesel filter pump needed replacing, which they did.

3 weeks later and the fault has returned. I have faith in the dealership that did the work, and am hoping that a simple reset will clear the problem. However, I am worried about throwing good money after bad. Can anyone give me the benefit of their wisdom on this issue please.
 
Mind if I chip in with my sorry tale from today?

I traded in my 1999 TD Fiat Ulysse for a 2005 Ulysse 2.0 Petrol today. I drove it away from the garage, went for a bit of a drive, then on the way back, literally at the point of driving past the garage, the engine cuts out with this same error message. I walk to the garage and they have let me drive my old (trusty) 1999 Ulysse back home tonight with the promise that the garage will sort it.

I honestly don't know what to do - it sounds like this a common problem with no easy, straightforward fix (and one that I think the garage might be able to get to go away but WILL come back). As the car is used by my wife for childminding I cannot live with a demon possesed car that might cut out at anytime.

Do I just tell them I want a refund and look for something else?

Also, after driving it for a bit I found the multi-function display very dim and hard to read in sunlight, is that normal?
 
Guys, what is vital here is a knowledgeable garage .... or should I say knowledgeable technicians (as they actually do the work) with a good background on the FAP system. Using the correct equipment there really shouldn't be a problem in diagnosing the issue.

Thanks. THe technician has 12 years experience of Fiats. I'm not sure about the FAP level. I remember a while back, a mechanic with a generic diagnostic tool told me the additive needed changing, but nothing came up on the more specialised Fiat diagnostic computer when the repair was done.
 
It's a peugeot (with Fiat badge) however ask for a full diagnostic printout and post it up here. If FAP fluid (alot cheaper from peugeot by the way) is replaced or topped up the ECU needs to know this.
 
Without hijacking the thread any further, that also sounds useful for me.

I am going to ask for a full refund tomorrow and see what happens - I can't be done with owning a car that's failed me before I've even got it home from the garage, but if I run into difficulties and I have to take the car, then I'll ask for the printouts and post them up :)

Just back from the garage. The diasgnostics showed a fault with the overboost valve (I think wrong pressure). The technician is fairly certain (90%) that it is being caused by a broken throttle butterfly spindle. I have arranged for the repair to be done this week, at a total cost of about £50.

He can't be 100% because he obviously needs to test it again once the part has been replaced, but seemed confident that this is the cause of the problem.
 
I had the Throttle Body Vacuum Valve replaced to day. It cleared the fault on the diagnostic. Will update again in a few weeks if the error doesn't appear again.
 
Still no problems. The work I've had done seems to have done the trick....hopefully.
 
OK, the problem hasn't reared it's ugly head, so fingers crossed the work I've had done has done the trick.

Hope this helps anyone out there with this problem.
