Technical Ulysse Orange light = Performance on hills?

[danielroch]

Hello Fiat Forum!

We have a 52 reg Ulysse Eleganza 2.2 Diesel (84000 miles) which is displaying an orange light and an anti pollution fault warning message. We were told by someone if you rev it for ages then turn the engine off and on the light will go. It did go but has come back. The car doesn't perform well on hills and we have been told its because of this fault. A garage has said that the anti pollution filter needs changing and then it should perform as normal. Is this the case? Anyone got any other ideas? The car is great on straight roads and small hills.

Thanks for any advice given

Sorry I can't see an edit button. My dad tried the following this evening:

- Cleaning the MAF (looked clean when off) and looked at air filter (looks clean too). Didn't help with the hill, still slugish, still has orange light.
- Drove with the MAF disconnected which didn't improve anything. Orange light still one.

I've been looking and wondered if it would be anything to do with the MAP sensor? Dad said that he thinks the Diesel filter doesn't need replacing as it drives on the straight fine. The car must be in limp mode, would the orange engine management light cause this?

Sounds like the diesel particulate filter is blocked.
Have you had your FAP fluid topped up (aroudn 50K miles)
This is the fluid that helps burn off the soot in the filter.
Driving at high RPM when the engine is nice and hot for 30-30 mins (high RPM is around 4K I think) and the car will try and do a re-generation which uses FAP fluid to burn off the soot.
Our car does it more and more often now and the trick above holds it at bay for a weeks or 2.
Options beyond that are replace the filter (in the exhaust in front of the CAT) around £200 or what I'm planning and open the exhaust and bash a damned big hole in the filter!
