1997 Audi Cabriolet Thumping Brake Problem

I need help :)
When I first start the car there is a thumping sound that I can feel through the brake and the transmission. When I step on the brake the thumping stops, when I let my foot off the brake it thumps again. It does not thump while I am driving either.I noticed the middle brake light also flashes with the thumping noise and the "Check Engine" light is on. It only does this while the car is idle. Is this a brake switch problem? we've already changed all the brakes etc.. but can't figure this one out.
Thanks in advance for any help

Hello

I need to ask a question to start - given your username, and that you refer to the car as a 1997 Cabrio, is it possible you're talking about a Volkswagen Cabrio, and not an Audi Cabriolet?

If it's a VW, let me know, and I can move this thread to the appropriate forum.

As for the symptoms you describe, I don't know what to make of the brake light and CEL, but if you're feeling the thumping through the brake and transmission, is it possible you might have a bad motor or transmission mount?

That might be a place to start looking.

Hi Rick,
Thank you for your reply. I used to own a 1992 VW Cabriolet so that is why the name is still wabbit. I now own a 1997 Audi Cabriolet. This is the car that is giving me the strange problem. I took it into my mechanic and he said It might be the brake switch or a transmission switch. I just can't figure it out. The car does not run as smooth as it should so I'm thinking transmission? But why does the brake light flash? It does occasionally jump out of gear when you come to a stop and go to drive.Very strange. I hope someone can help :)
