Hi all newbie here. I have done numerous searches regarding this issue and can't seem to find an answer, I have a 56plate 2.0tdci 6g with immobiliser active on the screen along with low battery and the mileage had turned into ----- first thing I done was change the battery as I wasn't sure how old this one was that didn't help and the same messages were on the screen. I returned the battery and got a replacement but still the same issues. Had a man come out and scan it and it came up with U0151 and C1d14. Anyone have any ideas on what could be the issue. Thanks
