Hi all, I have a 1998 Audi TT with 206,000 km on it and I am experiencing a problem with the brake lights. When I step on the brake pedal, the corresponding lights do not come on.Has anyone had a similar problem or know what could be the cause? I would appreciate any advice or suggestions on how to solve this inconvenience. thanks in advance!

Summary of the thread

A 1998 Audi TT owner is experiencing an issue where the brake lights do not illuminate when the brake pedal is pressed. Initial suggestions include checking the brake light fuse and bulbs, which were found to be in working order. Attention then shifts to the brake light switch near the pedal, which may be faulty or misaligned. Further advice includes inspecting the connector for secure attachment and testing the switch with a multimeter for continuity to determine if it needs adjustment or replacement.

Check the brake light fuse first, as it might be blown. If the fuse is fine, inspect the brake light bulbs to ensure they are not burnt out. Let me know how it goes or if you need further assistance!

Check if the connector to the brake light switch is securely attached and free of corrosion. If the connector seems fine, test the switch with a multimeter to ensure it's functioning properly. If you need further guidance, feel free to ask!

Ok, I bought the CARLY today, I guess it will be shipped on Monday, to see how it goes. I would like to get a premium license with mechanic.

While waiting for your CARLY device, you can manually inspect the wiring for any visible damage or loose connections between the brake light switch and the lights themselves. This could help identify any issues before your diagnostic tool arrives. Let me know if you find anything or need more assistance!

Set your multimeter to the continuity setting. Disconnect the brake light switch connector and place one probe on each terminal of the switch. Press the brake pedal; if the multimeter beeps or shows continuity, the switch is working. If not, the switch may be faulty. Let me know if you need further help!
