Removing battery on 2007 bmw 3 series

I can see the battery in the boot of my 2007 BMW 3 series tourer and can see that there is a metal bar to remove first. But then there is what looks like a red plastic box of electronics and cables on top of the battery. How can I get this off first so as to remove the battery for replacement? Will I lose the radio code?

    Brian: Thank you. It has several cables coming from it. And two bright metal things that look like clips. Do you know how to remove this box so I can actually get at the battery terminals. I intend trying to keep the electrical system alive by using a slave batter and jump leads but I think there may not be a radio code as nothing in the instruction handbook mentions the need to reset the radio, just the saved stations.s

    The box should fold up and away from the battery? I'm not familure with this model but if you need to then the clips probably clip off and you can lift the box off. I wouldnt bother with the jump leads and slave battery given the length of time you'll spend tryin to do that right will probably take longer than actually retuning the stations. Safe to say if the handbook does not mention a radio code that your safe

    Thanks again Brian. Further complication, and sorry to be such a pain. I understand that with a late model BMW such as mine (2007 E92) the diagnostics need to be reset so as to tell the cars computer systems that a new battery has been fitted and of what type, so as the car charges the battery at the correct controlled rate. Do you know anything about this? Bryan

    Your not a pain lol. I dont know about diagnostics needed to reset. Is there anything in the handbook about this regarding the removal of the battery? Your safe bet might be to go to a dealer. I doubt they would charge for a battery replacement if you bring the new battery. Alternatively ring a dealership and ask?

    Am getting headache from confusion. Have now emailed KwikFit, Halfords and also my local BMW. If the BMW price is too horrific I will ask them to estimate for just fitting a battery I would bring them. Thanks again.

The red box is probably the fusable links and cover on the positive terminal of the battery. It should flip up so you can see the positive terminal and disconnect it. Not 100% sure about the radio code on BMW's. In general some lose the code, others dont

SOURCE: Radiator removal BMW 316i

hi, the two clamps that secure the radiator have a small slot on the top, if you insert a small screwdriver into the slot and use it as a pry bar you should be able to unclip the holding clamp and it then releases like a hinge.

SOURCE: radio has no sound or intermittent e39 5 series '00.

You might want to suspect a stereo amplifier. Does your car have DSP? In any case, look in the trunk on the left hand side. You will find your radio amplifier back there. It will have about a 3in connector with a bunch of twisted pair wiring. Remove the connector and make sure there is no water contamination. All sound processing takes place in the amp.

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

SOURCE: 1999 BMW Z3 radio code

I have same problem need to get the serial number off of the back of the radio and the vin# and give that info to the dealer and he will have the code. If code still does not work ask for a different code since they installed radios from different manufacturers.

I have a BMW316i Tourer (1992). There is a problem with the central locking. I can only lock the car via the boot or via the alarm. I am unable to open the drivers door at all and the key wont turn in it.

Try to spray some WD40 inside the lock cylinder through the key slot, sometimes when the key not in use for a long time it's getting rusted and stuck.

Parasitic current drawn on battery on bmw 530 d tourer 1999

put an ammeter in SERIES with one of the battery cables. pull each fuse and take a reading. when it goes down to the correct draw...whatever that is, that would be the circuit with the excess draw.

Power seat, horn, alarm, anything powered without the key is suspect.
