My 200 did this, turned out to be a fault on the alarm immobiliser, I disconnected this one night and no discharge

Reckon the solenoid in the door seized and shorted something on the circuit board

But specific I know, but first of all have you had the battery tested?

You may have a cell down on it, if so no matter how much charge you give it, it wont last

Not every problem can be solved with duct tape, and it's exactly for those situations we have WD 40

try unplugging the glow plug relay. I get this problem now and again but since unplugging the relay its been fine.
Mine has a new batt and alternator fitted,
its worth a try and dont cost owt! it starts perfect without glow plugs anyway so i'll leave it as is

Where's the glow plug relay on a 300TDI Disco?
