[159] [langtitle=en]Error Code U1722 Alfa 159[/langtitle]

[Diveboy]

Hi All, Got a weird issue with my 57 159 Sports Wagon 2.4l.

Keep getting a gearbox warning codes are as follows:
Gearbox U1722 - CAN Line - Connect with gearbox selector (NCS) signal not valid, test complete or not applicable, Present, Not Requested.

There is another code that shows on other modules, that might be related??

U1602 - CAN Line error, Bus OFF, Intermittent.

Seems to be getting more common now. Any help/advice is greatly received.

Here you have the only topic I've found. Damaged wire harness going from passenger side to body computer.
Are there any symptoms or just stored error code?

No symptoms at all. Bit slow to start but that's glow plugs I think.
