Technical Changed Fuel Filter- Still *Check Diesel Fuel Filter Warning.

[Marin993]

Hi everyone. I drive a 2008 Fiat Bravo 1.9 Multijet. Few weeks ago i got a *Check Diesel Fuel Filter message on the dash. So i changed the filter, but every once in a while i still get that message. What you think is the cause for this. The car runs perfectly fine.

Hi.
What is the specific fault code?

It could be a warning of low rail pressure

 

[Marin993]

No fault codes recorded.
Also the weather here is kind of cold and i don't usually leave more than 10-15 liters of diesel in the tank. Could that be the cause?

Maybe

'Waxing' of the diesel could give the same effect as a partially choked filter

I hope that's what's causing that annoying warning light.
P.S. What are the symptoms of low rail pressure by the way?

Check the connection for the water sensor on the fuel filter clean the plug ups bit
Assuming the 1.9 has a water in fuel sensor?

When my punto sensor failed it flagged both fuel temp and water in..

Same sensor.
