Hey, thanks for your quick reply! The problem has been occurring for about two weeks. I haven't had any changes to the vehicle electrics, but the last inspection was about a month ago. The warning light that comes on is the one with the battery symbol. My mileage is at 187654 km. Any idea if this could be the battery itself, or should I look more towards the alternator? Thanks again and best regards!

Hey, no problem, gladly! So, if the warning light with the battery symbol lights up and the flickering of the lights, the longer cold start times and the weak battery when starting come together, then this is a strong indication of a problem with the battery or the alternator. I had similar symptoms with my 2018 VW Tiguan Diesel. In my case, it was ultimately due to the alternator, which was no longer charging correctly. As a result, the battery gradually went to its knees. I had to have the alternator replaced and then the problem was solved. In your case, with 187654 km on the odometer, it is also possible that the battery is simply at the end of its service life. The garage can test this fairly quickly. Of course, it could also be that a cable or connection has come loose or is corroded. What you could do: - Have the workshop check the alternator and the battery. - Check the battery connections yourself to see if they are loose or corroded. - Maybe there was something that was overlooked during the last inspection, so check there again. Hope this helps you and you get the problem solved quickly! Best wishes and good luck!

Hey, thanks for your detailed reply and the helpful tips! I will definitely have the alternator and battery checked at the garage now. It could really be that the battery has simply blessed its time with my mileage, or there could be a problem with the alternator. I'll also have a look at the connections myself to see if there's anything corroded. Thanks again for your support! Best regards!

Hey, I had a similar problem with my VW Golf Diesel, built in 2016. My battery was also low when starting, and I also had flickering lights and occasional warning lights in the speedometer. My level of experience with cars is more like "a little experience". At my garage, they determined that the fault was the result of a secondary fault in the vehicle's electrics. They checked and fixed it, and it actually cost me 0.0 euros as it was due to warranty work. To give you more tips, it would be helpful to know: - How long has the problem been occurring? - Have you had any recent modifications or repairs to the vehicle electrics? - Which warning light comes on exactly? I hope this helps you! Regards.
