One major concern (air coming from brake pedal) was addressed over one year ago and was not resolved at that time. It was then resolved approximately one year later during this most recent visit with a replacement of the brake booster. I am still not sure why this was not resolved on my first visit when I originally brought this matter to the attention of both VW Corporate and the dealership.
By the way, the speedometer is still inaccurate, the brakes still squeal, the ABS braking system still causes my brake pedal to vibrate irregularly (unlike any other car I've driven) and there are still rattling noises coming from the front console.
Today, a new problem arose: while attempting to go out and buy a Valentine's Day gift and flowers for my wife, the ((!)) red emergency light (and buzzer) came on about 100 meters into my drive. I turned around and went home immediately to call for assistance. I let the car cool down, and started it again about 10 minutes later, but this "Transmission Overheating" light/buzzer came on again upon restarting. Eight (8) hours later, I turned on the car again and the light/buzzer remained on. I called Roadside Assistance (as the Owner's Manual informs us not to drive when this light is on) and I was told that my car could be towed to the dealership and worked on after the holiday weekend. I had to borrow my wife's 8 year old Honda to successfully go out and buy her a gift. I now will not be able to take my car on my vacation as originally planned. This car has proven unreliable many times in its short 40,000 km lifespan. I believe that the quality of VW workmanship has become increasingly poor since it was outsourced from Germany to Mexico. I do not think that these vehicles have been properly safety-tested at the manufacturer for cold Canadian winters as these problems seem to surface, re-surface and intensify during low temperatures.
