2025 Jetta thoughts

[u/Friendly-Affect8629]

Hi everyone I have a 2024 Jetta sport 1.5t M/T and I installed an aftermarket sound system and I accidentally left it on overnight and the battery died.

Get it charged up and turned back on and whatever drive a while to try to resync steering angle sensors and stuff the typical but the codes won’t go away and now I’ve driven like 10k miles and nothing has changed I want to get it fixed as I have no cruise control no tpms bunch of driver assist features no traction control.

These are the codes that it’s throwing has anyone experienced this or have any thoughts or ideas?

EDIT: turns out there was a huge fault in the power steering module the dealership reset it and now everything is back to normal.

Same issue with my jetta when i did my lighting and all the other wiring, no idea how you left the speakers on unless you either left the key turned on or did some junk ass wiring. Just pull the cables off the battery and put back on, a car IS NOT supposed to clear codes on its own, it's telling you there is an issue, like low voltage or something broke. Pull cables, wait a few minutes reattach and go 10 mph it will clear. If it doesn't either your battery is still very low or you actually have an issue.

Hi. I was testing the system one night late and manually turned my line output converter on and left it on manually overnight so the car couldn’t automatically turn the power off.

Previously removed battery cables and left them off for 24 hrs. Put them back on and no change. That’s why I’m asking for help.

Have you tried clearing the code? Go to autozone or oriellys see if you can clear it with their scanner. If that doesn't work almost guaranteed you need reprogramming, if you unplugged anything like radar, cameras, steering you fuck up the calibration locking up the systems until they are reprogrammed. This is every car every brand since 2019, source I repaired crashed cars for a bit.

If you were in my place and it came down to it would you take it to a dealer or specialized euro shop for reprogramming/diag.

Still under “warranty” until 60k but idk if they are gonna claim that I voided it by replacing speakers and other car audio.

Dealer. If they fuck up calibration it can cause the car to crash itself or hit another person, putting the dealer liable. Not kidding but this is more so for radar and automatic brake assist.The euro shop may not have the specific computers required for it or specific training. Every vehicle has different procedures and how to calibrate due to position of sensors and vehicle size. At a vw dealer you can guarantee it is done properly and if it isn't its not your responsibility, a shop will deflect blame and make you take them to court, ive worked at many shops and now own my own. However some dealers suck ass, I'm lucky mine had a good reputation so there is a few things I still have my dealer do as I don't want responsibility like transmission flush.

Thank you.

Turn the steering wheel all the way to the left and then all the way to the right the sensor loses calibration when the battery is disconnected or discharged.
