Why does my Audi 80 start shaking when I reach high speeds?

I have noticed that when I reach speeds of over 80 mph, my Audi 80 starts to shake. Is this due to an issue with the suspension or could it be a problem with the engine?

It is likely that the shaking is caused by an issue with the wheel alignment. It would be best to take your car to a mechanic to have it checked and potentially adjusted.

I had a similar issue with my Audi 80 and it turned out to be a problem with the tires. Make sure they are properly inflated and check for any signs of wear or damage.

My Audi 80 also shakes at high speeds and it has to do with a misfiring cylinder. I suggest getting your engine checked to see if that could be the issue.
