Summary of the thread
A 2018 Skoda Superb is experiencing issues such as longer cold start times, failure to start, strange engine noises, low battery, flickering lights, and warning lights. These symptoms suggest potential problems with the vehicle's electrical system, possibly involving a faulty control unit or loose cables. It is recommended to use an OBD-II diagnostic device to read fault codes for more precise identification and to consult a specialized workshop for further diagnosis and repair.

Hey, thanks for your answer! My Superb now has 187654 km on the clock. The error messages that are displayed include "start-stop system faulty" and "engine fault". I recently had the diesel filter and battery replaced, but the problems persist. Maybe it really is something bigger in the vehicle's electrical system. Kind regards!

Hey, thanks for the additional info! With your mileage and the problems you mentioned, it really sounds like something deep in the vehicle's electrical system. The "start-stop system faulty" and "engine malfunction" errors indicate that some control unit or sensor connection is acting up. In my Octavia, it was also hidden electrical problems that caused all the symptoms. For example, it could be a faulty control unit or a loose cable causing the voltage fluctuations and thus the flickering lights and low battery power. Have you ever tried reading out the fault codes with an OBD II diagnostic device? This could give you and your garage a precise indication. Otherwise, I would definitely visit a workshop that is well versed in vehicle electrics. Sometimes a specialized workshop can help more than a general one, especially with such diffuse faults. Good luck and keep us up to date on how things progress! Best regards!

Hey, thanks for your tips! I haven't actually tried to read out the error codes with an OBD-II diagnostic device yet; I'll try that now. Your hints about hidden electrical problems and a possible faulty control unit sound very plausible. If I don't get any further with this, I'll take your recommendation to heart and visit a specialized workshop. Let's see if the professionals there can find something that my previous workshop missed. I'll keep you up to date! Best regards!

Hello, That sounds to me quite simply like a defective battery. If the battery is faulty, the start/stop system usually no longer works. I would buy a new battery and then of course have the battery programmed.

Is it possible to check the battery before I buy a new one? Do you have any experience of what I need to consider with a new part?

Hey, I had a similar problem with my 2017 Skoda Octavia (petrol). I would say I have some experience with cars. In my case, the cold start times were also longer, the engine was making strange noises and the lights were flickering. After a few unsuccessful attempts on my own, I went to my garage. The diagnosis was that the fault was the result of a fault in the vehicle's electrical system. Fortunately, the repair was free of charge as it was covered by the warranty. Can you give me more information about your Superb? What error messages are displayed? Perhaps I can then help you more specifically. Best regards!
