Well I went into the garage to get the D2 out this morning (well late morning), switched on the ignition, waited for heater plugs to go out and then cranked over.
Very slow and unable to start.
Got the garage battery out and jumped it fine but it did seem a little lumpy at first when it fired up.
Been out in it and its OK and starting first time every time. Running great.
I did have flashing M & S on dash at first but cleared them on the nanocom.
If I am correct I last used the D2 a couple of weeks ago and since then its sat in the garage. We have had -7.5 one night but nothing more severe. Is that enough to knock the stuffing out of the battery?
I was away for three days and when I returned my daily runner (van) was difficult to start too but that was mid week.

As the others have said, cold will kill a battery, however, my old D2 had a mystery battery drain. Even in summer, if I left it more than 5 days, the battery was almost dead and needed a jump start. Strange thing was, I always parked it facing down the very slight incline of the drive, so, when we went on holiday for a couple of weeks, I left it facing the other way for easy access to jump start it. When I tried it on our return, (Just really to see how dead it was) it started no problem! I did the same when the gearbox died so we could jump start the engine for towing it to the garage (I had to leave it a couple of weeks) and again, it started no problem! It seems my battery drain problem didn't occur if it was facing even slightly uphill! Strange...
