Crank, no start

Hello!

E90 330D 2005. Was sitting for 1 week, the battery drained in the cold -25C winter. I replaced the battery, now i have crank, no start (traction, abs, flat tire, gearbox etc faults showing). The car started up perfectly beforehand. I connected bimmerlink, it says "no communication from ECU". Both the car and bimmerlink worked together perfectly previously. Any ideas?

I checked the blue relay next to the ECU, checked the plate on my battery (all fuses are fine).
