Hi all problems 2003 HSE 3ltr td6 Trans failsafe prog air suspension inactive dcs inactive just put new battery on please help
 
Yes 13.84 running
That is too low so you have a problem either with the alternator or the connections like the earth strap. Immediately after starting you should see between 14.4 and 14,8 volts at least. If you have jump leads, put one from the battery negative post to the engine block and see if the voltage improves.
 
If the voltage is low before you start the car the ECUs may not fire up correctly, and they don't generally recover even when the voltage comes up. That said at that mileage it's probably due a rebuild as well.
