Peugeot 307 HDi 2.0 not starting

[Skids]

Car will not start first thing each day since the cold weather. Brand new glow-plugs, fuel filter bowl drained and still nothing. Turns over fine, but won't catch, until the battery is drained. I think it has electric fuel primer, not manual, which runs during pre-start with the glow-plugs. Checked the battery before starting today, 12.3 volts. Cycled the pre-start ten times before starting then tried to start. It turned over until it drained the battery. Jumped it from my trusty reliable BMW and it started in two goes. Any ideas?

Change the battery.

bring the battery in overnight and charge it properly. I've just been out to start mine and it didn;t work and i only charged the battery up 2 nights ago, it is the cold weather, I'm getting this battery swapped on Friday, does yours have a 2 year guarantee with it or is it older?

if it jumped ok, then it really must be a battery issue.

My sons Skoda had the same symptoms. Wouldn't start from its own battery but would with a jump start from my car. I checked with my multi-meter and one glow plug was duff. Replaced that and all OK.
Is it possible that one of the new glow-plugs is duff? Sometimes a fault in manufacturing leads to an odd one being duff from new.

Turned out to be the starter motor. It wasn't supplying enough low pressure fuel to the high pressure pump during starting. I found this out when the starter motor burnt out.
