Re: Stuck trunk
Ok guys,
I have disconnected this android radio, and ran autoscan.
Unfortunately our communication Issue Isn't solved. But we now have access to our G85 slip ring! with one not so pretty fault.
Edit:
242 000 km - Meaning this was while it was on a donor car. So we are good. (date also matches)
Next step:
I will have to look at the schematics and see what do power steering pump modul and abs brake module share and go from there.
There are three possibilities.
1.) Faulty abs modul ( but the abs works fine- it is pulsating the brake pedal when slipping on braking)
-I did re-seat the connector on abs pump, it looked dry and normal
2.) Faulty power steering module - I doubt it since i replaced it while ago and put new connectors. So no moisture problems.
3.) Some wire-ing issue between these two. ( I have noticed that there was a repair done on the loom in the engine bay i think between gearbox and the fan... it might have been a purple wire- not sure)
------------------- I will have to get a probe light---------- Open the abs connector and probe red green wires to see if we have power on ABS module. If thats ok then the canbus should be ok - I have no scope to test this out. Maybe measure the voltage and see. i think it should be '+6v or +5v on can lines.

Re: Stuck trunk
Update:
This G85 DTC isn't clearing.
Maybe flashing this module with odis might clear the dtc 
On another note, the hand brake sensor light- magically started to work again. Had hopes it might have restored communication. - No.
For now i have tested the fuse box on the battery with test light. Alles gut.
To do:
When the rainy weather stops.
Check if the resistance on CAN hi- Low on abs pump connector Specification is 60-70 ohm. If ok then can-hi low wires are good towards abs pump.
Check power check gnd, its its all ok- Faulty abs pump.
G85 works normally i can see the guide lines, cornering lights etc.
Stalks i had one issue, one silly push button on trip computer slipping. Lol buying used parts never know what you are going to get... lol.
Disassembled the lever ( easy) slip a card between trip button, and the plastic shell so you can pry under. Slowly go around.
The fix.
1. Put some cloth/ tessa tape on the litle levers that touch the button, so it doesn't slip.
I did it for both switches.
https://youtube.com/shorts/FGT-hVfF-9M? ... 7A-y3A2ETr
put everything back, this finger resting plastic peace can go only one way.
Now the lever doesnt slip on the button and is good.
Enjoying the ccs- those buttons arent slipping... so far

Re: Stuck trunk
Thanks for the detailed information!
It would be great if you could figure out the problem with the CAN line, I would focus on the repairs that were made previously.

Re: Stuck trunk
I'm referring to wiring repairs for the ABS, power steering, etc. that were made with the previous owner.
The engine has the same CAN powertrain line and is accessible by diagnostics.
As a suggestion:
If you can't find the fault in the wiring, and in test mode, you should run new CAN line wires to a point where it would be possible to diagnose the missing units.

Re: Stuck trunk
Ok guys,
today the weather was nice and i had the time.
Unwrapped and unboxed the abs connector.
Using test light.
Grounds on abs connector confirmed
Power from the fuse box sb9 ( the one inside the car requires ignition on to test) to the abs pump connector
Power from Sa fuse box ( on top of the battery) to abs pump connector
Cabus hi-low resistance is ~60.2-63.8 ohm meaning the canbus wire-ing towards abs pump is (spec 60-70 ohm)
Its hard to take a vid, and hold the test leads. Because i had thin needles inserted into the connector. ( And we dont want lost needles in the engine bay).
I ran diagnostics while abs pump was unplugged, our steering assist 44 didnt come to life.
and ofc. abs module on vcds became red with no communication.
After plugging it back in, it came with sporadic communication fault.
After clearing all dtc... back to usually issue.
And when the pump is plugged back in its black, doesnt show faults and cannot be reached.
Conclusion:
- Abs pump s**t it self
- What is funny no warning lights on the dash. Only while the abs pump is unplugged.
- I have to check the power steering pump. Forgot to bring a t25 torx to remove the fog light...
But im pretty sure it will also return ~60-70ohm on can hi-low. and the power is good since the pump is running.
So yeah...
you trw and your pumps.
When i fit the downpipe, i will have room to upgrade the abs pump.
Also it seems that over voltage fault cleared from the g85. I ran diagnostic these 2-3 days and it came back clean.
Maybe its not a bad idea to get a obd2 breakout box, and when person is unsure in canbus connection just run can hi low directly from module to the brekout box....
Id' like a second opinion on this dilemma.
The car from i grabbed the g85 ( had that over voltage fault)
Now this car has the "AS" pump i want ( 9.0i). Is it smart getting the abs module from that car?
Why im asking is because they didnt remove it from the car.
Meaning i can also grab the two lines going from brake master towards the pump ( i think i have to replace mine, the esp 9.0 have thicker lines?)
Or its fine to reuse my hard lines.
I will keep this topic updated, note. it might take some time untill i put new abs pump.

Re: Stuck trunk
The intermittent fault detected in the G85 was the result of a malfunction in the communication or power supply lines at specific times, both before (the donor car) and after (your 6R). It's not a sign that the potential donor 9.0i pump is faulty.
I insist
. In external way, run any two wires as a test (they don't need to be twisted together), from the IC's CAN lines to the pump's CAN lines, and verify communication with the pump using the VCDS. You can use alligator clips to do this.
Original lines are always welcome as long as they're in good condition.

Re: Stuck trunk
Conclusion:
Ran a scan with Odis ( had a vas5054a sitting for years collecting dust - I know last time i used it- few years ago i couldn't reach these modules) but now
no issues.
Definitely adding heat shrink at bcm did help, and i can sleep now since we have communication.
Live data works, meaning everything is OK.
So yea, for you all budget folks STM32f405vgt6 is trash, and hex-can Atmega was good an did read these module ( not promoting, but someone might find it useful). Go for real deal if you can ofc.
ELM327 did scan the module like it had no issues, but no identification.
For me this is good enough, I can reach the abs pump. Friend has launch, and i will borrow it and do a scan with it.
If you cant reach these modules (if you have power, and you suspect on bad can hi/low, continuity fails, resistance fails), then definitely listen to ciclo, and run new can hi-low lines. Again the easiest place to splice into is back of the cluster.
I must thank ciclo once again for sharing his feedback, suggestions, tips and his time. It was pretty fun, and definitely i learned something new.
Ran a scan with Odis ( had a vas5054a sitting for years collecting dust - I know last time i used it- few years ago i couldn't reach these modules) but now
no issues.
Definitely adding heat shrink at bcm did help, and i can sleep now since we have communication.

So yea, for you all budget folks STM32f405vgt6 is trash, and hex-can Atmega was good an did read these module ( not promoting, but someone might find it useful). Go for real deal if you can ofc.
