8Y RS3 starting issue/safety malfunction resolved (final update) Part 3

[S3DUDE]

I will link/attach the two previous related topics below. The car is finally fixed!!!

Click here if you want to see the original topic from a couple of months ago with a temporary fix:
https://www.audizine.com/forum/showt...xplained)Click here is you want to read from my second update a few weeks ago:
https://www.audizine.com/forum/editp...69&do=editpost

Here is a quick summary before I explain everything: 8Y platform is affected by battery management that affects not just the starting of the engine but will trigger multiple safety related faults. The solution is a TSB that address a specific software that targets the battery to keep the state of charge above 85% and not 80% like I was explained/told on previous topics.


Symptoms (will display some or all of the messages below besides not starting):
1) Car will not start
2) Distance warning
3) Engine start system malfunction-"please contact service"
4) Parking assist currently unavailable-please take over the steering
5) Stability control warning
6) ACC unavailable

** Keep in mind that the car could randomly start all of the sudden even if previous attempts were not successful but warning lights and messages will display. Also, keep in mind that car can start with a small momentarily voltage increase or small battery charge period of a few seconds.

What cars does this affects to? new 8Y platform specifically A3,S3,RS3.
What fixed the car this time? TSB 2069999/4
How was this situation addressed? Local dealer could not initially duplicate faults. Had to created a case with Audi Technical assistance(Audi Engineers). Engineers suggested running specific test/diagnostic.
Can you run this TSB straight up from the get go? Not necessarily. If your technician does not see all the necessary fault codes stored needed for this TSB then they wouldn't run the TSB. That is what happened to me the last time.

The difference between my last visit and this visit is the amount of fault codes stored. The last time my car other faults codes that were not called for this TSB. This time my car threw 5 out of 6 codes needed for this TSB.

Best of luck to you guys. My suggestion is that if this happens again to you have them take a look at TSB 2069999/4. your car might not be a candidate for this TSB based on not generating the proper fault codes but this TSB address the 85% state of charge needed on the new battery management software that triggers all kinds of malfunctions. This 8Y platform comes with a very sensitive voltage/state of charge measuring collection that affects the functioning of the car.

Glad you got it sorted, unfortunate you had to jump through so many hoops but it's nice to see the Audi engineers step in and solve this.

I have to say I really did think your issue was the same as mine. I guess I was just lucky that the codes were enough to match the TSB details.

And I am glad that you said that because I think you are correct and that is why I posted the other links. You could technically bring the car to the dealer and they may or may not duplicate the faults but also your car may or may not stored all the faults needed for the TSB (that was my first case).

Update from 28 February. Here it goes again!! Taking my wife's RS3 to the dealer for multi safety messages that wouldn't go away after starting the car and turning it off and re-starting it. Her car starts but many safety messages are showing and the lights are staying.

This is the second time it has happened to her but I never opened a topic addressing her car. If you combined the faults, messages and non-starts we have 4 total combined issues (two on her 2023 8Y and two on my 2024 8Y). The difference between my car and her car is that my car failed to start and hers started but the CEL/messages stayed on.

I have an appointment on the March 13th to drop off the car. Are you guys taking notes? Stay tuned for any updates.

You should sage your house man lol you guys are cursed! Hope you get it sorted but wow - stay away from Vegas :x

I'm supposed to take delivery in April and it's threads like this that don't fillllll me with confidence.

Hope it gets sorted out.

Remember: for every 1 forum post about a particular issue, there are 100+ others out there enjoying their car without issue and not posting anything. This issue is the definition of an anomaly. Hope OP gets it sorted once and for all!

The opposite could be true as well: There could be 100+ others out there having this same problem, but doesn't get reported because not everyone is hanging out on forums. How do you think TSBs get generated if no one else reported the problem?

Problem unresolved yet (Day one- March 13th). The 2022 RS3 is throwing only one code out of the six codes needed for the new TSB. Further diagnostic needed and a request (inquiry) for a solution through the Audi engineering department has been sent. The service advisor thinks that is all related to the TSB (battery voltage/charge management) but the diagnostic tool only registered one fault code.

Obviously they don't want to just clear the code and release the car, we need to find out why all the safety messages are displayed. Just stand by for more updates. I got the feeling that this eventually is going to lead to a mandatory recall/TSB. Years ago I called it out way ..way before the seat pod sensor was a mandatory recall, I reported it back then on an Audi S3 7-8 years ago and it got to the point where Audi could not even sell traded cars (Audis) with that recall undone.

There you have it. 3 days without a car, no TSB applicable because it doesn't throw the proper faults for the TSB and car wouldn't duplicate the discrepancies because it happens rarely and randomly, specifically it did not happen during the 3 days that the dealer had it and drove it.

The safety messages warnings we have it on video though. We are back to square one from the standpoint of a car displaying safety messages and knowing that the dealer can't figure out what is causing it. They followed their diagnosis techniques but at the end of the day nothing positively fixed. From the legal stand point I have two more of these occurrences up to November of this year and I can turn this car as a Lemon (4 safety issues in a 2 year period and not being fixed).
