Kamold's R36

[kamold]

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...
