Problems with flickering lights and low battery in Mercedes X-Class Diesel (2018)
(Translated from German)
Summary of the thread
A 2018 Mercedes X-Class Diesel is experiencing flickering lights and a weakening battery, particularly during startup. The issue may be linked to a defective battery sensor, as suggested by a similar case with a Mercedes E-Class. The recommended solution is to have the battery sensor checked and possibly replaced at a garage, which typically takes about two hours and costs around 315 euros. Regular servicing is also advised to prevent further issues.

Hey, thanks for the answer! My car is an X Class and already has quite a bit on the clock with 180187 km. Well, and it's been a while since the last service. How long did it take you to change the battery sensor? Isn't that related to the electronics? That sounds like it could be more expensive.

Hey, no problem! Honestly, it could very well be the battery sensor in your car, especially with the mileage. You should definitely have it serviced if it's been a while - your Mercedes is generally a robust car, but even that needs servicing. It took about 2 hours to replace the sensor in my E-Class. The mechanics also checked the electronics, but that wasn't a big problem. The cost of the sensor and the work was actually around 315 euros, as I've already mentioned. So not a mega high cost. I would recommend that you have it checked at a garage. Don't get stuck on the road or anything! Hope that helps you!

Hey, this is just the help I needed! Thank you so much for taking the time to answer me. Your experience sounds very similar to mine. I'm reassured to know that the replacement only takes a few hours and the cost is reasonable. I'm going to take my car to the garage tomorrow to have it checked. I really don't want to risk breaking down on the road. Thanks again for your advice. Your help was really worth its weight in gold!

Hey, had a similar problem with my Mercedes E-Class diesel (built in 2016). I would say I have a bit of experience with cars. It turned out that the battery sensor microprocessor was defective. I paid around 315 euros for the repair at my garage. The guys there did a great job and the problem was fixed afterwards. Could you give me more information about your vehicle? Model, year of manufacture, maybe even mileage? Then I could go into more detail about your problem and perhaps help you better.
