Hi all my 320cdi keeps throwing up the above code which is evap vapour emissions or somthing similar (cant remember right now)

It clears ok for a day or two then comweeks s back.

Has anyone dealt with this as am perfectly fine with engines and normal mechanics etc but dont know anything about this system on the car.

If anyone can advise on the system or better still a fix that would be greatly appreciated.

Many thanks
 
Hi,
I have copied this from another forum,
P02025 = The signal voltage is too low or too high The atmospheric pressure between the pressure sensor downstream of air cleaner and CDI control unit is implausible.

The only suggestion there, was to remove and clean the pressure sensor with Electrical Contact Cleaner. There was no confirmation that this cured the problem.
Sorry I cannot be of more help.

Steve
