Check for power coming out of the socket using a test light or an electronic tester. It could be a problem with the wiring or bad relay that would need replacing.

750LI E60 4.8 ENGINE USES 6.9 QUARTS OF OIL WITH NEW OIL FILTER.YOU SUPPOSE TO USE 5W - 30 GREEN LABEL SYNTHETIC MOBILE SCH630.

In the bottom of the radiator... there is a nipple that allows the connection of a hose, the observation that you make about the leak, is located in the nipple (could be a crack in the solder?) or you refer to hose itself. If the hose could be two things:
- Leak caused by a bad fit in the bracket
- Leak caused by dry, cracked hose

Check and make their comments.

the cooling fan fuse is located in the main fuse panel,location of which should be in your owners manual if you have one if not call the dealer and ask.it could be the cooling fan motor itself not working or the cooling fan relay.to check the cooling fan if you disconnect the plug on the back of the motor and feed direct power and ground to the terminals of the motor.if the fan starts to work then it is okay.to change the cooling fan it is a job for a shop to do as it entails alot parts removal to get to the fan itself

Changing the headlamps on this year BMW may require removal of the front bumper. I would recommend that you take it a BMW dealer for repair.

There is a allen fill plug on the side of the tran towards the back.the trans temp should be around 50 deg c,with the engine running remove the plug,the fluid should just trickle out of the fill hole.

I have not seen this particular model but the reservoir should be toward the front of the engine compartment on the (US) driver side, It has a big black plastic cap about 2.5" in diameter with indentations around the perimeter to grip. On some models they had to tuck it down where you have to reach down between other components to get to it, but on a 7 I would expect it to be up high and easily accessible.
This model came with two styles of reservoir. The standard reservoir is about quart-sized. If the car has self-leveling suspension, the reservoir is taller.
If you intend to own the car a long time, I suggest changing the power steering fluid every 2-3 years when you change the brake fluid and the coolant. If the power steering fluid is not nice and clean and red, it needs changing.

Most likely a short or the Alternator is not properly charging the battery and electrical system. First check the wires that go to the starter and lead from the battery to the Alternator for any breaks or possible shorts that are allowing the Positive wires to ground. If those are good, disconnect the battery positive wire and connect the jumper cable directly to the positive cable and jump the vehicle. Once it is running disconnect the jumper cable and test the voltage on the positive wire to see what the alternator is sending as a charge to the battery. Anything less than 12 v is an obvious problem and I believe it should charge at 14v but you would have to check the book on that. Your other option would be to remove the alternator and have it tested at one of the Auto parts stores that offer to do that, Auto Zone and Advance Auto come to mind. If there are no shorts and the Alternator is good then that leaves the Alarm system and interior lights as being the problem and you will have to isolate those areas for shorts or constant connections. You may have accidentally set your interior lights to constant on which would bypass the timer system if you have one. Check the dash brightness control knob to make sure it isn't turned all the way to one side or the other. This position typically sets the interior lights to constant on.

The window motor has probably worn out. They are cheap to replace and can be done in less than 10mins. Very simple to undertake yourself.

the first thing i would check is the fuse for the power trunk closer.

You want to get a coolant that Contains no nitrates or phosphates so it will reduce the chance of harmful deposit formation. There are many types of coolants you could use. Bmw makes their own but you could also use Final Charge coolant, Texaco Extended life, Volkswagon Pentosin Lifetime Purple coolant, Havoline Extended life. Those are a few and there are many more, hope this helps.

Help you this picture?!

Are you getting the code P0173 That would mean that the ECU was unable to set the correct mixture for cylinders 4-6 (bank 2). I'd guess that the most likely culprit for that failure would be a failing pre-cat O2 sensor based on the code alone.The pre-cat O2 sensors are a critical part of the feedback loop for mixture control. When an O2 sensor ages enough it no longer delivers a valid signal to the ECU, which can cause this fault. The only other component that will affect only bank 2 is the catalytic converter for that bank. Given relative costs of O2 sensors and catalytic converters I'd change out both pre-cat O2 sensors and see if that helps. FYI: O2 sensors are usually staring to fail at 80-90K.

V12 6.0 motor = N73 type
V12 5.0 motor = M73 type

You mused in I-Drive set RPA/RDC and reset it

Use a I-Drive controller,menu,vehicle setting,central locking, locking after move it set in ON position

unscrew this 4 TORX screws and door panel pull outside and up

The battery may be located in the trunk near the spare tire.
