The car was running smoothly until one day, it just sounded so badly and the wife thought the engine was blown. It’s still drivable, shaking at idle and losing power because sparkplug #1 physically popped out of the head with all threads still good… Amazing. I started to look for a new car until I opened the engine cover to see what’s actually going on. Again, if we got panic and towed the car to any shop/dealer… money will be spent for nothing. Thanks to Quattroworld.com Audi enthusiasts, sparkplugs popping was suggested and they’re correct… Got to love the internet.
