Citroen Relay U0019 fault codes help

Unread post by guyan23 »

My Citroen Relay 2.0 35 Enterprise BlueHDI has been in storage for a while and I am now getting it ready for the mot but I have some fault codes which i need help sorting.
The van starts ok with no problems and the only light on the dashboard is the DPF which I am in the process of cleaning.
Using a scanner it gives me the following fault codes.
P1448:97 Which is the DPF
Built in Systems Interface U0019 - Fault on the Comfort/Body CAN (CAN -B) - No activity on the CAN
Instrument Panel U0019:87 CAN fault.
I also notice whist scanning was in process and scanning the engine Management ECU the dashboard throws up a EBD failure warning -see handbook but does not record this as a fault - the only fault recorded in that section is the DPF issue.
No mot so can't take it on the road to see if any lights come on or maybe this would help to reset things?
Can anyone point me in the right direction.

I'd suggest you complete the DPF clean and reinstall it and then reset all the codes and see what comes back when you start the engine. :)
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!
