Search for solutions to battery problems and flickering lights on Skoda Karoq Diesel 2019

Yes, this happened to me in a similar way with my 2017 Skoda Superb Diesel. I have very little experience with cars, so I did a bit of googling before I went to the garage. It turned out that the alternator was faulty. This cost me around 960 euros at the garage. I can therefore recommend that you first have your car checked by a specialist garage to determine the exact problem. To be able to help you in more detail, however, I would need more detailed information about your vehicle. For example, what is the mileage and condition of your battery?

Hey, thanks for the quick feedback. My Karoq has run about 31087 km. Just had it serviced recently, but unfortunately they didn't find any issues with the battery or alternator. Hope I can solve this soon, it's really annoying. Your tip will definitely help me, I'll try another garage.

Hey, we have almost the same number of kilometers on the speedometer, I had my Superb checked at about 30000 km. It's stupid that they couldn't find anything - sometimes these electrical problems are really hard to diagnose. Before I discovered the fault on my alternator, I was a bit lost too. I suggest having the fault in the vehicle's memory read out again - maybe something was missed last time. Also ask about the alternator, as that could also be the problem. Maybe you could also try a full charge of the battery and see if the problem persists. Batteries can be tricky and sometimes they show no obvious signs that they are broken. Let's hear how it went. Hope you get it sorted soon - good luck!

Hey, yes, it really does seem to be an annoying puzzle. Thanks for pointing out the fault memory, I'll have a look at that. And the alternator and fully charging the battery also sounds logical, I'll try that too. Thanks for the helpful tips and for sharing your experience. I'll get back to you as soon as I have any news. Take care and thanks again!

Can you help me?

Of course, I'd be happy to help. Could you please provide more details about the issue you're experiencing with your car?

I got the DTC_00668 code for supply voltage terminal 30.

The DTC_00668 code indicates a problem with the power supply terminal 30. This could be due to a weak battery, a faulty alternator, or a problem with the wiring. Start by checking the battery's health and its connections. If the battery is in good condition, check the alternator's output. If both are fine, you might need to inspect the wiring for any damages or loose connections. Please update us on your progress. Do you have any other questions?
