Kamold's R36

[kamold]

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.

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.

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.

[kamold]

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.

Had some 'fun' yesterday...

I was messing about with VCP (never advisable) looking at the CCM and managed to wipe the data on my factory CCM EEPROM (which contains the encrypted immobilizer data).
So the car wouldn't start.
Had 5 mins to get down to pick up my son from school. So got to run down there in the heat.

Took the CCM back out and reflashed it from the EEPROM dump I had already taken last week (tip for young players, always have MULTIPLE backups of critical systems!) and apart from having to run the G85 steering angle sensor calibration again, car is happy again..for now

Reinstalled the new 3AA CCM today and messed around with coding until I fixed it all up (First 6 bytes of the coding are not well documented so I had to use trial and error to get it all working. I have a feeling its RHD specific).

Car is now locking and unlocking all doors and flaps properly! And I have convenience menu in MFD.
I've lost TMPS but that just means I have to retrofit the B7 TPMS which will give me individual wheel tyre pressure display in the MFD.

TPMS high kit arrived today.
Its a relatively straight forward installation:
Remove rear bumper to mount controller
Connect power
Run CAN cables to front and connect to pins 7 and 17 in a 7N0 gateway.
Add TPMS to CANbus gateway installation list
Install new sensors in tyres
Adapt new sensors

But...
Before i can install the 7N0 gateway I need to change the wiring from the Electronic Steering Column Lock which changed in the B7 (to match my B7 CCM - pins 8 and 10 need to be bridged) otherwise the car will complain every time you turn it off of a steering column problem.

So have a bit of work to get it all going but a good learning experience.

Tonight I replaced the collapsed seat foam in my driver's seat. Was a bigger job than I thought but I had a friend help me.

Tips - move the seat back all the way forward and seat angled all the way up to ease access to the cover for removal and insertion.
- remove baby seats from behind to aid in giving room to remove the seat
- the seat is easier still to maneuver if you remove the steering wheel (which I decided to do as I wanted to fix my ESCL wiring anyway)

The seat now feels brand new. I have to now be careful to exit and enter as much as possible without too much weight on the bolster to get this one to last as long as possible.

Then I corrected the ESCL wiring for the B7 3AA CCM and put my 7N0 gateway in.
No steering error on shutdown now!

TMPS install next week hopefully...

The old cushion

Thanks for sharing a photo. Very interesting to see the internal damage to the seat.
Yes ... entry and exit by lifting over the side bolster seems to be the key to longevity.

Front seat out and steering wheel off (optional)



New seat cushion



Finished and back in. Brand new!

I have 2 manuals. One says the steering wheel bolt must be replaced each time. The other manual says the bolt may be undone and tightened 5 times before it must then be discarded. So I marked the bolt head with 2 indentations to indicate 2 uses.

[kamold]

Yeah supposed to be 5 times Max then get a new one.

Now that I have a 7N0 gateway I thought I'd try this modification to enable fatigue detection:

7N0 Gateway Müdikeitserkennung – dunt.at

Use google translate.

I now have the option in my assistance menu (the only option there... )



Haven't tested it yet (although I am tired I don't think my drive home will be enough to trigger it) but at worst its something I can turn off...
