2010 Audi A3 Quattro Q&A

2010 Audi A3 Quattro Question: Steering jerks left and right on it's own while driving.

Problem is constant at both high and low speeds. Dealer says everything is fine since the service computer shows no problem. Have requested the tech test drive it with me next week. In the meantime, any help appreciated. Thanks -

I am having this EXACT same problem with a 99 Ford Escort - no reason for it. I've had an alignment; rotated back to front tires and replaced a wheel bearing. Now were trying tie rods. Anyone know? -
