Agreed on the extra connector point. However it is very unlikely that any 12v lithium battery would exist without an internal BMS, These batteries appear to be build with 4x leV60F cells. All lithium batteries require a BMS to balance power within the cells. However in this case I would guess...

Thank you, at this point I suspect my best option is to ditch the Lithium battery (maybe I can sell it on mrkplc for $800 :o) and go buy an old fashioned AGM. The BMW Lithium battery does have a 2 pin management plug. As I write this it makes me wonder if redirecting the Audi LIN to this port...

2018 Q7 attempting to replace the OEM AGM with a Lithium 69AH battery with a LifePo4 (from BMW F80). The battery is basically a drop in for a similar AGM. The problem I am having: When I set the coding to "Lithium FeP" as well as other parameters 69ah, random serial #, etc. the car starts...

I found this thread which mentions a similar if not identical issue. @piotr303 did you resolve this issue? https://forums.ross-tech.com/index.php?threads/38516/

Can you clarify what is meant by " is 44 or adaption or dataset." ?

Yep, that cleared and took me from 4 codes down to 3 :)

Back to original issue. So current status is still just those 3 codes. Any ideas on adaptations for the j500?

Uwe, Thanks for clarifying, I know my cable is part of ancient history, but I can't let it go :). Actually I was almost 10 years off, I purchased it in 2016. Your order #100094070 Placed on July 26, 2016 10:11:04 PM EDT Item in your order Qty Price VAG-COM Diagnostic Tool with...

I know that my cable is from 2007, so it has no UDS. Does this prevent me from clearing these codes, or does it just prevent me from getting the descriptions?

The most likely scenario here is that there is an adaptation necessary for the new steering rack which has not been performed. I searched around and was unable to find anything beyond the steering angle settings. The rack is working perfectly and beyond these 3 codes there is nothing else that...

Ok, thank you for following up. In my case the replacement rack is working fine, provides normal feedback, etc, the only problem is these codes. Perhaps i will just code out the assist, I would never use it anyway.

To bring back an old thread, what was the final solution here? Is there an adaptation necessary for new steering rack on this model? Other than steering angle setting? Thanks

Ok, I was able to get the steering angle done, I was using the wrong controller, I wasn't in 16. Now the remaining codes are back to the 3 for Steering Assist 3149825 - Databus U1121 00 [009] - Missing Message [Message_ACC_10_Time_Out] 5570561 - Databus U1122 00 [009] - Implausible Message...

Ok, that would explain it. So, moving on from there, I believe my next step may be to perform a steering adaptation, but when I enter basic settings I only have the drop down with 4 options, not the menu described in the in the 83g or 4g steering angle adaptations.

I'm hoping someone on here can help me with these codes. Just purchased a 2017 Q7 with a few minor issues. I usually avoid used dealers at all costs, but the price on this was good and I felt like i could handle the issues. It is clear that the dealer/PO replaced some components such as...

After running IDE03567-ENG167462-Calibrate installation I got a full batch Airbag errors for all 3 airbag modules with no ability to reset. And dash lit up with ABS errors. Not sure if it is because I wasn't able to run the second IDE?

I was not able to find IDE13545-ENG167462-Reset analysis measured value was ask for Security Access. What module is this in? Or is there another way to access IDEs directly?

Hello everyone, I need some help. I have been chasing problems with my S8 5.2 v10 for a while now and I'm a bit stumped. I replaced all plugs, swapped some coilpacks around, swapped out the oil separator, checked for vacuum leaks, and did a carbon cleaning but the problems remain.I feel that...
