DS4 Additional Battery Alarm Error

Hey, I had a similar issue with my DS4. I would suggest a battery check to see if the auxiliary battery has any problems. It could be discharged, which is a common cause of alarm system malfunctions. It is important to check this, because the alarm system depends on it!

Thanks for the tip! How did you solve it? Was it definitely the battery, and was it expensive?

Well, it sounds familiar. Yes, it was indeed the battery and I advise you to go to the workshop and let them replace it. In my case, the low battery charge was due to ageing, and I had to replace it. I paid around 330€ for the whole repair.

Thanks a lot for the info! I'll get the battery checked and probably replaced then. Sounds like the most likely cause. I appreciate the help!
