My brake lights are stuck on all the time!! Why?!?!

He never followed up after that, so don't know. I would recommend, however, checking Fuse #4 and Fuse #2 in that fuse box diagram I posted, above. When he writes "PIN #4," I'm assuming he's referring to the #4 fuse position. GTI's, above, seems to think it's fuse #2, so just check both - first. Again, since this is clearly not the fuse for the tail light BULBS... and it's the fuse for the brake light SWITCH -- I'm guessing that it would be easy to confuse the correct fuse position.

PINs refer to connectors in wiring, notice the yellow circle that is a T4bc/4. That means that is a 4 pin connector and it is bc or the 29th 4pin connector in that type of car and that is PIN number 4. T4bc/2 PIN 2 for ground T4bc/3 PIN 3 to J519 and T4bc/1 PIN 1 to ECU. The red circle goes to Fuse SC2-> fuse number 2 side of dash. If that solves OP issues they need to get their money back from dealer.

It's most likely a NAR vs ROW thing or the fact that it's a 2005. I replaced the master cylinder and there was no bypass. Maybe if you change it to ROW in engine and/or instruments with VCDS it would change this behavior?

I am thinking that a bypass would not be a good idea if your car is equipped with cruise control as clutching in disables it (not sure how à bypass works though)?

The bypass I am referring to is the clutch pedal switch F36 or G476 Clutch position sensor G476, I am sure that you have one. Number 12 in pic.




This is the bypass that can be installed so you can start a manual car without pushing in the brake pedal, perhaps the previous owners installed one. What does your owners manual say about starting a manual car??

Any update from your father on the fuses?

Thought I'd bump this one more time for everyone's edification. It would be great to know if the OP ever resolved this issue - and even if he did not, what was tried and did not work.
