The alternator output looks a little low considering the battery state.

The only fault code that is related is 03041 - Energy Management Active
Code is stored when the car has to start switching things off to preserve battery life (infotainment, lights etc).

What do you have switched on? any aftermarket extras?

EDIT: try loading the alternator - start up with everything switched off. Then switch aircon, infotainment, lights on - see if the output drops.

May be worth checking the DRL. Also check drain on battery (with multimeter) when you lock the car. Could be a leak somewhere.

1. First fault is a faulty glow plug in cylinder 2 - easy fix, best swap it out asap.
2. Second fault you can ignore as this is part of the battery fault.
3. Third sounds like a door lock isn't unlocking or locking - someone else on here may have a suggestion on how to test the locks.

thank for the reply

ill get the glow plug changed and test the battery out

[danny851]

Do you think i should replace all 4 glow plugs or only the damaged one,
i have never changed the glow plugs before the car has done 93000miles
