Problems with the electrical system and battery in the Audi Q3 Diesel model year 2015

Weak battery when starting the engine

|

Dim or flickering lights

|

General electric malfunction

|

Fault stored

Hi, I'm having some strange issues with my 2015 Audi Q3 diesel at the moment. The general electrical system is acting up, the car is storing errors, the lights are sometimes dark or flickering and the battery is weakening when starting. I suspect something to do with the disconnection of terminal 30. Have any of you had similar experiences or do you have any troubleshooting tips for me? Would love to know how your garage fixed the problem and what your general experience was. Any help would be greatly appreciated!

Hey there, I'm not a mechanic but I do have some experience with cars. Had a similar problem with my 2013 Audi Q5, the reason was a faulty battery sensor. The garage fixed the problem for 315 euros. Have you already put your car in an OBD scanner to see what error codes come up? Without more detailed information about your vehicle, I can't be of much help. Hopefully I was able to help a little anyway. Let me know if you have any more information!

Hey, thanks for the tip about the battery sensor, that sounds plausible. I've already done an OBD scan but this battery sensor error didn't come up. Well, I'll see what happens. By the way, my car already has 95000 km on the clock, and the last service was a few months ago. I just hope it's nothing serious. I'm really not in the mood for expensive repair costs. Thanks again for your help!

Don't worry, I'm happy to help wherever I can! I can understand that you don't want high repair costs. With my Audi, I'm always worried when something strange happens. If the battery sensor error didn't show up in the OBD scan, it could also be a problem with terminal 30. Have you ever checked the wiring? A loose cable or a bad connection could be causing this flickering. Maybe you can find something there. And do me a favor and stay tuned, I want to know if you get your problem solved. Good luck and keep me posted, buddy!

Thanks for the further help and for the good wishes, buddy! I'll have a closer look at the wiring and terminal 30. Hopefully I'll find something useful. And of course, I'll keep at it and keep you up to date! Maybe there will be a solution without expensive trips to the workshop. Your tips were really great. Really cool of you, thanks again!

I have a problem with my steering when I turn the wheel I get noise

The noise when turning the steering wheel could be due to a variety of reasons such as low power steering fluid, worn out or damaged power steering belt, or issues with the power steering pump. Start by checking the power steering fluid level. If it's low, top it up and see if the noise goes away. If the fluid level is fine, then the issue might be more complex and it's recommended to have a mechanic inspect it for safety reasons. Please keep us updated on your progress.
