hi have you checked battery health also your alternator should have a 3 pin connector on. (this is for the lin bus this is a network which includes glow plug relay and alternator) make sure this is plugged in and the two wires are ok, did you replace the alternator and did you replace it with a merc one or like for like, sorry for too much information just thinking out loud

have you had any luck with it yet. have you checked the alternator is charging if so do you have access to a code reader also check the connection on the electrical housing box (big black box under the bonnet)where the control units hide there are two main battery leads that connect to the box check that these are tight not cracked or corroded

Battery Light
on my 639 111cdi 2011 model it was the blue yellow wire from alt up too ecu ,it was chaffed causing high resistance, this causes alt to go to default charging mode usually about 14.3 volts. repaired wire cured the problem.
