Brake Hoses, Lines/piping, And Fittings problems of the 2002 Volkswagen Passat

When the outside temperature is below freezing, the brakes on my 2002 Passat wagon do not work. The brake pedal is hard, and will not depress. I have been told by a mechanic who has worked on my car for the past ten years that there is a significant amount of water in my brake lines. This water may have entered the brake lines from the brake booster in a manner described in incident report #pe07018. Attempts to fix the problem have been unsuccessful so far (water has been drained out of system, drains have been cleared of leaves and other debris, but the problem recurs when the temperature drops below freezing). Does vw have any other suggestions how to fix this problem? when the problem happens, I do not have functioning brakes (a rather dangerous situation, to say the least).

The contact owns a 2002 Volkswagen Passat. When the contact started the ignition and attempted to engage the brake pedal, there was no response as a result of a frozen brake line. The failure would occur during cold weather temperatures. There was an opened and closed defect investigation associated with NHTSA action number pe07018 (service brakes, hydraulic: power assist: vacuum). The vehicle was not diagnosed or repaired. In addition, on a separate occasion, the engine stalled and emitted blue smoke from the exhaust system after a rain. Also the engine warning light illuminated. The vehicle was previously repaired for the engine failure. The failure mileage was 113,000.

First cold evening of November 2008 (below freezing) brake pedal failed to depress, and brakes appeared to be completely locked. After several minutes of warming up, brake function partially returned, but without power assist. Husband flushed dot4 brake fluid through abs regulator, brake lines and bled brakes. No change whatsoever. Waiting for dealer to recognize problem. Dealer failed to acknowledge problem over phone, however, this may help. Believed that air/power booster sucked water in to brake booster from defective drain. Sunroof also leaks, and 3rd set of cv boots for car in 3 years.

The contact owns a 2002 Volkswagen Passat. In 2007, the contact stated that water would drain into the motor during heavy rains, and cause the brakes to fail. The dealer discovered that water was entering the brake line, but never informed the contact of a recall. Instead, the dealer repaired the brake system and stated that it was a courtesy from Volkswagen. After the repair, the failure recurred and the brakes failed while driving 30 mph. The contact noticed thick, white smoke coming from the exhaust pipe. She had to strike the wheel against the curb in order to stop the vehicle. The following day, she took the vehicle to the dealer and they made repairs again. The failure mileage was 21,000.
