I would check all earth wire on your car , as it sounds if there is a bad earth wire or a broken one ., this would explain your battery going flat and the flat battery would probably cause your problem with the steering as it will probably be an electric steering pump

Check your brake fluid. If it is empty you have a leak somewhere. If it is full it sounds like you have a giant air bubble in your brake system. Bleed the brakes and the clutch slave cylinder.

System needs recharging , check v belts ok. Ur on compressor prob, electronic control unit on dash maybe faulty

check all fuse and relays most likely could be but if there all good could be crank sensor or cam sensor or coil

voltage regulator

push in and hold the sunroof button (30 sec) and the sunroof will go through the entire recalibration. That should fix it. __________________Hi apperently this is a common problem for BMW but this fix should do it.You will have to do it again if it happens. Good luck.

disconnect the positive cable from the battery for a couple of minutes to see if it resets if it doesn't work take it bmw

First check the fuse. Check the sunroof and make sure nothing is jamming it. If these do now work, see your dealer.

Probably not. Almost all newer cars have to have the battery attached to keep running, once its detached or dies, it will most likely stop running fairly soon, if not right away.

If you have a multimeter remove and test the fuses for continuity (OHMS) as fuses can look OK but they have blown. If your replacing fuses ONLY replace the with one of the Same colour and Amp rating.
