2002 Fiat Scudo • 214,000 miles

Hi I have a 2002 Fiat scudo 2.0L Diesel with an engine managment light on, the only errors I have are = Accelerator Pedal, cylinder reference sensor, Fan 1 unit, Flow meter, pre post heating relay. There have been no codes whatso ever, just what I have stated, the van is a bit smokey when you put your foot down. Any ideas anybody?

Can you advise on the exact code set and by what you say I am thinking that this is a drive by wire engine? If your personal scanner is not reading this, you may have to get a factory read done as many generic scanners will not read all codes.

Right well I cleared the fault codes, and only 2 have come back up, accelerator pedal & pre post heating relay, but still no codes. I ve been using a Texa Axone 4 which is usually pretty good.
