You can swap them, but need to get the keys programmed to it, and to do this you need the bar codes for the keys . Also if the car has a different spec some other things may also need programmed, aircon for instance ..

 

When you say program the keys - is that just for the remote locking or for the transponder that enables the ignition?

 

Just for remote locking, I replaced mine with a new one and everything worked except central locking / aircon and heated rear window . The central locking worked from the key in the door just not remotely . I was then told If I got a 2nd hand one from a car with aircon that would work as well .

 

that's good to know - Mine's got the climate control so I'm guessing I may have issues with that and the heated front screen, but as long as the car will start that will be good. Also mines a convertible and I'm guessing the donor BC1 is from a r53 so that might scupper some things too..

 

Old thread, but... a mate with a 2003 R53 replaced a bad BC1 with a used one, and everything is working now except for the sunroof. That I think can be sorted with NCS expert. A bigger problem is that the traction control light is on and clearing the fault code gives an error about a wrong VIN. Is it possible to change the VIN in the BC1?

 

Thats correct, I just came her to comment that yes they are a direct swap but the VIN must be matched onto the replacement. Not sure if NCS will do this, but NCS will certainly be able to correct the settings to match fitted options. I know WinkFP can do things like VIN coding, but things like the clocks and ews cannot be recoded without removing the onboard chip but i know the BC1 can

 

you sure its not just the lock mechs?

 

First thing you need to do is code the module in using INPA once that is done go to the BC1 in NCS and code and blank document to it, The module should work everything out but failing that you need to code the VO/FA to let the BC1 know what you have and then you can add the functions

 

What version of INPA do you use mate if you dont mind me asking? I thought INPA only does service functions when i looked at mine no programming options?
Cheers

 

Version 5, navigate on to the module and you will see along the bottom of the screen there is an option to code the module in. Mine is quite change now since the original - failing that it is easy enough to do it through NCS

Its been a while since I last coded in a module on the R53. As long as you have NCS you can always;
Using expert mode read the ZCS and select the "BC1" ECU for coding. The job is quick and doesn't take too long.

My mini is running modules from all eras and models and this is all I did to keep it coded

 

My 2004 R53 has failed its MOT on all indicators not functional, local vehicle electronics specialist has diagnosed faulty body control unit! i can get a matching partnumber one for cheap from fleabay, can I just plug it in and the indicators will work to pass MOT? and i can worry about getting keys etc programmed later? also, whats this NCS software? i already have a wifi obd adaptor for my other car, is this something I should know about? i presume i can only get the keys linked to replacement bc1 by someone with hardware/software for key programming? Thanks.

 

Hope someone can help i have swapped out the BCM and now need to get the Key Programmed so the central locking works from the key itself, How would i go about doing this with NCS software please?
