OBC Hidden Fuses 1995 525I

[Mihigh]

I am going trying to fix my On Board Computer on my 1995 525I. I have replaced every possible fuse, bulb and can't get the thing to turn on. I have been told that there are 4 fuses associated with the OBC? Does anyone know where they are located? Thanks for the help...

Bentleys says 3 fuses: 1,17 and 20 in your fusebox

So again... there are 4 fuses... The problem with the hidden 4th is that it is associated with the anti-theft control and is hidden somewhere in the car. On newer models I have seen pictures of it close to under the back seat and have searched and searched. No luck... Please someone, anyone... Where is the location of the mystery fuse? I think it is a 30 amp.

On my E32
Under rear seat left side in driving positon inside the support for the rear seat there is the module for the drive away protection, and that goes to the OBC to activate the protection with the code on the OBC.

If you cannot see it immy, feel with your fingers for 2 screws under the carpet on that support more in direction to the center, it must be there, at least on my car it is there and I also found it on the parts car E32.

Yep thanks... No luck. This will be my mission... lol I will tear this dang car apart until I find that fuse. I searched for two hours last night and still couldn't find it.

'95 model has DWA IV, you should find the DWA module on the inside side of the bulkhead supporting the rear seat- 1" forward of the power distribution box. The box has to be removed to get to it... and it has a set of fuses in it/near it.

Take a look and yo will see.

BTW, If the module is missing, the OBC will not work and neither will the alarm.
