Take out and you will need to locate the BM54 unit therefore it can be taken or sent to a repair site.
The actual BMW BM54 repair is normally so straightforward the unit may be returned to you on the same day it is received, or done in a few hours ( in case you take it in to a repair centre yourself) to be picked up on the day you drop it in.
You'll find a BM54 unit in some Land; the BMW 3 series; and the BMW X5 and Range Rover models. Your owner's manual should tell you what model of unit that is BM54 you've got in your vehicle.
The BMW BM54 repair begins with fault analysis - so you need to inform your engineer what's wrong with the unit. Common faults in the BM54 contain decrease of audio to one or more Auto Electronics channels; total loss of audio; or just a number of the loudspeakers working. Know that simply the loudspeakers in a single area of your vehicle are flawed, or if one of your speakers is flawed, it may not be the BM54 unit at fault but wiring in the doors.
You can receive your BM54 unit before you send it away for the BMW BM54 repair checked for faults in situ. It's best to do this because you won't know for sure that it's the unit itself causing the issue. And of course should you send away that unit without a problem,, it's going to come back not needing fixing and you will still have that issue - plus you will have needed to pay the BMW BM54 repair centre because of its time.
You'll be able to try to ask the centre to which you are sending it to do a full BMW diagnostic test on it before they start to mend it, if you are unsure where to get a BM54 assessed before repair.
Every BM54 unit is located in a slightly different area - normally in the boot well, underneath the spare tyre. For directions on removing the unit that is BM54 before the BMW BM54 repair, refer to blogs or take a look in the manual of your manufacturer. In case you have some questions contact the business that is going to do your diagnosis and fix and ask their advice.
