Technical C2003-13 Fault Code

[robkerrigan]

Has anyone ever had fault code C2003-13 Valve Line Open Circuit? Getting 4x4 Unavailable on the dash.

Car was in for some work, discs and pads and one of the ABS sensors broke. Had all the lights on the dash and ABS unavailable etc warning messages. Sensor was replaced today and now getting just 4x4 Unavailable and the above fault

Anything obvious I should check?

May not be this based on the bigger picture, but the dash warning “4x4 unavailable” is often caused by a failing car battery — several previous posts about this and (I think) all cured by a battery change. Is your battery over 5 years old? Does your stop/start work ok?

Start stop works, but I've read the other posts about similar and see a fresh battery cured similar so I think I'm going to try that. Not had it long so no idea how old the battery is

I just wondered if something could have been dislodged or damaged when it was in getting the brakes done but looking more like an unfortunate coincidence
