WHAT SHOULD I LOOK AT FIRST
You need to look at the door lock actuators, I'm guessing 1 is operating but staying on when locked and draining the battery. Try manually locking the doors and see what happens. It may come down to removing the door trims and disconnecting each lock in turn, don't forget the boot lock, until you find the culprit. Its possible you may hear the lock solenoid humming or buzzing or feels warm as its trying to lock the door unsuccessfully.
There is no power going to the car radio in my bmw z3
Perhaps the connector behind the unit has become loose/disconnected? There is rarely enough play in the wiring harnesses of today's automobiles (In my opinion). A few good jolts over bumpy roads have pulled wiring harnesses out of place in many instances.

Causes cylinder misfiremw z3
Yes, it is very possible for the Mass Air Flow sensor (aka MAF) to cause a misfire. You need to replace the MAF if it's causing a misfire. More detail please if this doesn't answer your question
Replacing head gasket
Hi
firstly, do you have the equipment to change the head gasket.
ie: a suitable torque wrench for the head bolts?
do you know how to re-time the engine having removed and refitted the timing belt(which you should renew)
I`mj looking at the worshop manual now and I presume you know how to strip an engine
The important part is when you replace the head (having made sure it`s not warped or cracked) and having cleaned all mating surfaces, you should have ten cylinder head bolts the tightening sequence is ____________________________
8 6 2 4 10
9 3 1 5 7
_____________________________
the torque settings are assuming you`rs is a M.40 engine is stage1 30 n/m stage 2: angle tighten 90 degrees stage 3 angle tighten 90 degrees.
Good Luck
Doug
