I have owned a MK6 1.4 TSI 122 for 2 years, bought second hand at 55k. The power steering has always felt a little heavy, and especially so at low speed and parking. This week whilst driving at about 25mph, the steering lurched to the left then right, and I lost control of the car for several seconds. After stopping the steering is now much lighter, as it feels when driving a new car. I've read various posts online about steering rack problems, or faulty sensors, but never heard any about the steering becoming lighter. I'm taking it into a local specialist to get it checked out ASAP.

Anyone else experienced this problem?
