Problems with the brake light on a VW Tiguan 2012 - looking for experience and suggested solutions

Hello, I had a similar problem with my VW Golf, built in 2014. I'm anything but a car expert, but I have a bit of experience because I have to tinker around myself from time to time. I then went to my trusted garage with the problem. Long story short, it didn't cost me a cent. The fault was mine (user error), not a tangible problem with the car that needed to be repaired. Can you give me more details about your car? Maybe then I can help you better.

Hey, thanks for your quick reply. My car has about 138690 km on the odometer and the problem occurred when I last picked it up from the inspection. The workshop visit was actually just for the annual oil change. However, I didn't mention anything about the brake lights. Maybe I should have done that. I'll probably have to go back to the garage either way, but I thought I'd ask here first, there may be a simple solution I've missed.

Hey, no problem! I'm glad I can help. It's really strange that this is occurring right after an inspection. I would definitely suggest you go back to the garage and ask them to look at it, especially as the inspection was so recent. It could be an accidental fault. On the other hand, let me tell you a little something I once noticed on my Tiguan. I had a similar problem once, which turned out to be a faulty brake light switch. It's a relatively cheap part and easy to replace. You could make sure it's not the brake light switch before you go back to the garage. Just to be on the safe side. Of course, I'm no expert, but that could be the case. So give it a try and let me know how it goes. Good luck!

Hi, thanks for your time and the helpful advice! I will check the brake light switch tomorrow. If that's not the cause of the problem, I'll follow your recommendation and visit the garage again. I'll keep you and the forum posted on how things develop. Thanks again and have a nice evening!

Hello, I have a Volkswagen tiguan 2.0 TDI 4motion from 2011, I have a defect "P0633" that is often displayed I do not know what it is due.... Could you please help me?

(Translated from French)

The error code P0633 typically indicates an issue with the immobilizer key not being programmed correctly. First, try using a spare key if you have one, as the issue might be with the key itself. If the problem persists, it may require reprogramming the key or checking the immobilizer system. It's advisable to have a professional diagnose and resolve this issue, as it involves the vehicle's security system. Let me know how it goes or if you have any further questions!

Thank you for your reply, I have two keys and have tried both and still have this fault.

(Translated from French)

Check the battery in your key fob to ensure it's not low or dead, as this can sometimes cause communication issues with the immobilizer. If the battery is fine, the next step would be to inspect the immobilizer antenna or wiring for any visible damage or loose connections. If you're unable to resolve the issue, it's best to have a professional take a look, as it involves the vehicle's security system. Let me know if you need further assistance!
