    7L6 Touareg disable engine power retardation and RNS510 media system starting

    Hello,

    Two issues I'm stuck on with on my Touareg:

    1: I don't know the coding table for the ABS/ESP stability control to disable the electronic power retardation feature in the ESP ALLRAD MK25E1 module. It's still originally coded 0008450.

    Even with ESP disabled and centre lock locked, I'm still getting power delivery intervention in times of high power requirements. Pulling a trailer though sand I need wheel spin and power to the ground, electronic lateral differential lock intervention is manageable, but the power retardation isn't, all momentum is suddenly lost in this instance. I can crudely disable ABS with the fuse removal, but this also disables the centre lock.



    2: The RNS510 is sticking on System Starting on the Media page, and is failing to boot the navigation map. After an hour or so or runtime, a three key < > * reboot has everything return to normal operation.

    Do I have anything miscoded that isn't showing? There's no fault codes, also swapping the bluetooth modules and reinstalling the firmware 5238 has not improved this situation. I have a 3C8 035 730E bluetooth module installed, it works perfectly and is also wired for stereo music streaming, the Touareg Can Gateway just cannot communicate with it, so I use my Golf's gateway to communicate, but this bluetooth module was installed and used before this System Starting issue. It's also coded with the wifi off.

    Thanks for any help, also the door malfunctions below were just because I'd removed and reinstalled the doors.

    KIMIMIKE, loss of intermittent power.

    Read a case study one time and noted you pulling a trailer in sand. Just a thought here, and off the cuff for 2019, but sometimes noise transmitted through a trailer hitch will cause knock sensors to intervene, anyway, just a thought as can really kick your butt.

    The 7L6 hitch receiver is annoyingly noisy...oversized.. even with a clamp on it.

    Thanks for the replies guys. In my case it’s ESP kicking in and reducing wheelspin by reducing engine power after it gives up dancing with the brakes for electronic differential control. On a straight face with all wheels spinning equally, it’s normally ok, but go up something obliquely, or in a curve and it thinks itself to death, perhaps the yaw sensor vs wheels speed vs ground speed and steering angle all come into play. It happens without pulling anything too. ESP off seems to just have a longer time delay before intervention, but it reduces the yaw sensor sensitivity.

    On the RNS510 issue, it might just be the hard drive spindle seizing up in the cold? Once things are warmed up the Media page and GPS maps all come back. I’m still testing that theory before buying, cloning and installing a new 2.5” IDE drive.

    Mines just a manually removable Westfalia, it’s been sublime. https://goo.gl/images/L5d6Rg
    Didn’t feel like being lazy and installing the more expensive electrically retractable one.

    I'm skeptical that it's the hitch that's causing the behavior in question.

    For laughs, you could take a look at Adaptation Channel 90 in the ABS. I would suppose that the value there is a 1. If so, try changing it to 0. That should turn ESP off. However, I would also guess that this setting will not survive an ignition cycle. I'm also not sure whether this will kill the power reduction.

    I'm not aware of any other way to accomplish what you're looking to do.

    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.

    Thanks Uwe, I'll investigate that and see how I get on.

    I can now confirm the HD in my RNS510 is packing in and why the Media page is waiting on System Starting... and Navigation maps are timing out and not loading.
    Here's when it warmed up and running properly.

    I think I've heard of people replacing then with SSDs...?

    Yes. Impressive build quality in the RNS510, love the precision in the metalwork. I think anything will be faster than the 30GB 4200 Hitachi that’s currenty in it.
    SSD should be quite vibration resilient, China has a few IDE SSD options. Will probably need IDE to SATA converter as well to format in FAT32 and clone.
