Kamold's R36

If I come across another one with paddles down the track I'll probably swap it over and sell this one. But happy with it for now.

So I am trying a slightly more involved upgrade.

I have replaced the 3C0 CCM module behind the glovebox with a newer 3AA (B7) module in order to support some other mods. It has also brought the convenience menu back in my upgraded colour MFD...



Replacing the CCM involves dismantling the module and reading the EEPROM which contains the encrypted immobilizer code. I read this to a file using my trusty $50 minipro programmer (after much tooing and froing trying to get the pins to line up with the connector) and then wrote the file to the new CCM's EEPROM.





Installed the new CCM and the car started! I was concerned I would end up with a car that was permanently locked...
But this is not the end of the journey...turns out the ABS/ESP module is not compatible with the new CCM, so it gets grumpy and throws a fault which in turns causes the immobilizer to not want to lock the car. And my TPMS module is not contactable.

So I upgraded the software on my ABS controller to version 17 (was 11) which wipes out the coding, and the G85/G200/G201 sensor calibrations.
Reset the calibrations, but the coding is still not correct as the original coding is no longer accepted

So have some work to do in order to get the car into a healthy state again...

Smart and brave move kamold, look forward to seeing the resolve. However, this is well beyond me so I won't be giving it a go anytime soon

Replace smart with foolhardy perhaps

Looking like I might have to back out of this upgrade just for time being as I don't have the time to press on (looks likely that I will need to get a B7 ABS module as well as fix the ESCL wiring).
Put back the old CCM and car is happy again, key fobs work etc.
When I have some more time next week I'll try again with the new CCM.

In the mean time I'm going to play with DAB as I installed a new SSD RNS with DAB.
Not much different to what I already have I know but the upgrade to the LED screen and faster boot/route times is nice too.

After some trial and error (try one coding string, check faults, add 1, try new code etc) with some advice from a friendly fellow enthusiast in Estonia, I was able to find a valid coding string which allowed me to clear the faults from all the modules and restored ABS/ESP/EPB functionality.

Next step is to relearn the keys and I will eventually have to do a wiring mod to the steering column lock module to clear a fault from the immobilizer. But this is a bit of a pain as its right down the bottom of the steering column so I'll have to leave that for a later date when I have some more time.

Those Estonians are a nice bunch.

You're a lot braver than I am - and I've resoldered my dash from white to blue!
Very keen to follow this thread. Nice work.

Jeez mate slightly more involved is a bit of an understatement, haha. Pushing the boundaries with this one, unfortunate that it is probably not going to work out. Major props for attempting it anyway.

It's a stepping stone to acc which is my ideal end game.
I need to try with the new ccm and relearn the keyfoba again, that might get it working.
Lose tpms as I'd need to fit the newer controller that shows pressure per wheel in the mfd, our generation has the tpms module in the ccm itself.
