Hi.
I am new to this forum, but not Fiats.
I have a new 2012 Euro 5 Ducato 2.3 motor home. I have a couple of questions that my dealer appears not to be able to find. Maybe someone out there can help.
First off, I had a problem from new with the steering wheel being a few degrees off centre, making it appear I was permanently turning left. Also I find that there is a very small amount of free movement in the steering, so I find myself constantly having to correct to keep the van going in the right direction. I thought modern van rack and pinion steering would be as good as a car.
My dealer says they cannot find a problem. Trouble is when a dealer is driving around a town testing it short term, it is not like driving on mixed roads for a couple of hours.
I got the wheel adjusted to the correct position after asking a third dealer, but the free play is still a problem.
I recently had an ECU upgrade, and shortly afterwards started to experience a period of abnormal running when the engine is cold. I thought maybe supermarket fuel could be causing it, so I have had a couple of tank fulls of branded fuel now, but the problem is still there.
It feels like a slight flat spot when accelerating gently, whilst the engine is cold. If pulling out of a junction the engine feels flat. Pressing the accelerator harder, of course, brings you into turbo territory, which you do not really want when exiting 90 degrees onto a main road. After 5-10 minutes, when the engine has warmed to normal, it runs OK. As usual my dealer cannot find the problem. Not that I really expected a heavy footed technician to come across the problem. I need a good diesel engine specialist as I know there is a problem there somewhere. My other option is to sit with the engine running until it is warm and then set off, but what a waste of fuel.
Fiat Camper Care say they have not had any similar problems notified since their ECU update, so I am at a bit of a loss. Come the cold weather I can only assume it will get worse, as the engine will take longer to warm up.
Maybe somebody out there has come across a similar problem.
 
We have the 2.3 130 HP Euro 5 on a Frankia motorhome 3.5t. Yes it is just a little hesitant when cold but I find that if I don't accelerate hard it picks up slowly anyway. This is probably how it drives. I don't have a problem with it and we have done 8,200 miles since early March. We had the 2.8 Ducato before and it obviously drives very differently.
No problems with the steering though and we spent 8 weeks in Norway so just as well!
I'm getting over 28mpg (31 in Norway). Genuine.

Hi,
We have an 2011 Autocruise Rhythm which has pulled to the left since we collected it from new last October.

We took it to Northern Commercials in Morley, Leeds, but they were unable to sort it after several attempts. On one occasion they took it to their Brighouse workshop and it was definitely better, but not cured.

We have given up and now drive it with an off-centre steering wheel and a pull to the left. How many days can you actually leave a vehicle with a dealer before giving up - lifts back, lifts there, time off work.

The lumpy nature of our 2.3 Euro 5 engine WAS CURED by the ECU upgrade!

Cheers,

Ian
