I had this same problem back in November during a very cold spell.I had an appointment to have some "recall" work done on my 03 passat and told them about the STOP brake light. When I picked up my car, the dealer told me that it just needed some brake fluid??, so they filled it ! Well, I don't know about that, but I haven't seen that pesky STOP warning light since.

Could it be a battery shape? Red in color - means "Generator". VW recommends not driving if this stays on. Alternator belts may be loose or broken and/or electrical malfunction
