Newbie to BMW

[Matlor]

Got my first BMW last September and so far quite happy with it. It is a 3series 330d X drive in Individual Tanzanite Blue which looks incredible in bright sunlight. It has every option available except sun roof. 

I have coded lots of extra features if anyone needs any help with Bimmercode. 

Once i suss out what is causing my battery to drain in 3 days then it will become a brilliant car.

Hi Matt.....welcome to the Club

Is the battery the original one? may need replacing as lots of residual circuit consumption even when idle

Good to have you onboard

Morning Matt

Welcome

As Trevor says Battery may be the culprit, however with my X5 I had several electrical issues which I eventually tracked to poor earth connection at one of the multiple earth comb type points in the boot. Try opening the bonnet letting the car go to sleep and measuring the drain at the charging point in the engine bay, it should be in the low milli amp range.
