Brake Light and CEL!?!

[white 99 gsr]

Anyone know why my brake light in the dash would start flashing and beeping? It started about the time it started getting cold. I have a MKIV GTI 1.8T. Also my CEL is on and the code says "engine cooling system performance". Any ideas?:???:

coolant temp sensor maybe. brake light not sure. Usually it will some on to tell you to stop. Try the wear sensors, they will kick a light on too.

I just changed the coolant temp. sensor a couple of months ago. Maybe I should try flushing the system? Maybe I could change the brakes... I haven't changed them since I bought the car last Aug. I'll try that and let you know.

Thanks for the input.

If you just changed the ect then you are going to need a thermostat. If the red brake llight is beeping at you then you are prob low on brake fluid..

yea check brake fluid first, also visually look at your calipers, make sure a abs line or brake line isnt cut or bent or something. Had a truck a week ago come in he had run over a log and it cut his rear abs line
