Example complaints

“There is a severe safety problem associated with the Audi 94s4, other model year s cars and other Audi cars with the 100 body. When the plastic part that connects the throttle body to the throttle cable breaks, the engine goes up to 7000 RPM (over red line). If in heavily congested traffic as I was, the owner risks his life or his engine. Since I decided my life and that of my passengers was more important than the engine, I let the engine race and used the brake to control speed until I could safely get off the beltway and onto a side road. …”
