    Hello guys,
    I have a neu projekt now and maybe you can help me, it has something to do with ECU #16 and #44,
    normaly an EPS#44 need some external agle signal, it is an normal CAN message from #16,
    I connected EPS#44 to my CanRestBusSimmulation from Audi(it is Audi EPS), but I can not simulate a CanRBS from #16(to complex counter), thats why I always have a "External Agle Fail". then I connect #16(agle sensor) and #44 physically with cable, it was a solution from this problem,BUT now I need one more ECU... Can I hack the ECU#44(EPS) and say :"you do note need external agle anymore, work without it"? Maybe EEPROM programming? Thanks for reading,sorry I saw you write about#16 and maybe you have solution for it.

    i know that some power steering units should be able to work without steering angle sensor, at least in the lower specced cars like a polo.
    then the G85 is somehow integrated into the power steering unit.

    is there some long coding available for your 44 ECU that says anything about steering angle, ESP, etc?

    Is it possible to connect to 1K0 (or 8P0) comfort module via VCDS if it's paired with just a 1K0 Gateway on the desk? Removed from working car.
    Checked wiring at least 5 times. Only Gateway connects. Comfort says big NO.

    Convenience wiring i'm using:
    Code:
    pin 2  - 12v permanent
    pin 3  - ground
    pin 9  - convenience CAN-H (to gateway)
    pin 10 - convenience CAN-L (to gateway)
    Do I also need steering angle and central electrics to make it alive?
    It just ticks once when I turn on 12v source.

    I'm not sure. Some modules do require a "Virtual Terminal 15" (via CAN) from some other module, and it wouldn't surprise me if this is one of them.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Hi guys. Sorry for hijacking the thread Anyone would be able to help me with BCM terminal 15 wiring on A3 8P? I managed to power BCM up, but it won't wake up. Measure block 62 shows term 15 off, neither bcm nor cluster wake up. I can partially diagnose BCM, and fully diagnose steering module, and gateway with VCDS, and these show term 15 on on MBs. Any ideas?

    Any? OK

    Code:
    Ignition key solenoid N376 <==> Steering column ecu J527 <==> Onboard supply (BCM) J519.
    I'm stuck with the same issue. Trying to power up comfort module without using BCM at all.

    Is J681 relay physically on BCM? Slot B1 (KL15). No more clues.

    Shame. It worked with bordnetz without issue, but now I'm stuck. BCM does not have the kl15 relay. I had implausibe signal fault on gateway, but I short wired pins in D socket on j527, and then it disappeared, but still no power on term15 on BCM:/ Help! :-)

    Yeepee kay yay, I've made it lol. So ashamed to admit, but I kept miscounting flipping pins in C block of BCM, lol, got stuck on C-block, loool. I kept connecting pin 35 instead of 31 being sure it was 31 It's awaken now, wide awaken, the full bench.

    J519 BCM
    T52a/1 – KL30
    T52a/23 – KL31
    T52a/42 – KL31
    T52b/12 – KL15
    T52b/52 – KL31
    T52c/5 – KL31
    T52c/15 – CAN Conv H -> J533 T20/15 <-> J527 T20c/14
    T52c/16 – CAN Conv L -> J533 T20/5 <-> J527 T20c/15
    T52c/31 – KL15 aux output -> J527 T20c/17
    J527 Steering wheel module
    T8e/4 – KL31
    T8e/12 – KL15
    T20c/11 – CAN Powertrain L -> J533 T20/6
    T20c/12 – CAN Powertrain H -> J533 T20/6
    T20c/14 – CAN Conv H -> J519 T52c/15 <-> J533 T20/15
    T20c/15 – CAN Conv L -> J519 T52c/16 <-> J533 T20/5
    T20c/17 – KL15 aux output -> J519 T52c/31
    T20c/19 – KL30
    T20c/20 – KL31

    And obviously J533 connections, but these can be easily found

    hmm....... It's an absolute catastrophe of biblical proportions!! . Yes, something really odd has occurred to my (until now) faithful test bench and I seek advice as to a possible way forward!

    First here's what the beast looks-like:



    So - admittedly, I built the thing way back in 2016 and it's been subjected to numerous atrocities as various colleagues (mainly from a local forum) have tried to program the modules in ways that I suspect were never envisioned by VW. However, the thing has begrudgingly tolerated every abusive session that it has encountered: always firing-up and ready for more - that is, until this morning when the BCM apparently spat-the-dummy (a colloquial term for "refused to behave").

    While DTCs abound whenever an auto-scan is taken because of the artificial environment (see autoscan below), the particular error which is most concerning is:

    Address 09: Cent. Elect.
    Cannot be reached
    Unable to communicate with address 09. Are you sure the doors are unlocked?

    Yes, the BCM is registered on the installation list (note: no DTCs on the Gateway) and I've tried swapping the CAN high/low lines from a functioning module onto the the BCM with the same result. Other than the CAN comms problem, the BCM works OK - it correctly operates the simulated lighting board (see picture above) and the operation of the rotary light switch is unaffected - as is the simulated ignition key. Neither are the results of the autoscan affected by the volts from my power supply (amazingly, these modules seem to operate way down to about 7 Volts)

    No matter what I try, I can't seem to get the Gateway to talk to the BCM - can anyone suggest a possible fix (other than replace the module)?
