hello! i need some input! theres a weird thud like noise that feels deep, you can feel it, somewhere in the middle front im guessing..can be heard when going over bumps.....now heres the thing, ive even taken it to audi to check out, the suspension is all brand new so they ruled that out, and they couldnt find anything, they needed more time and i stoped them, cuz i dont hav money for their time lol.....anyone know possibly what could be something to check?? soo far the bellypan and suspension are ruled out, what else could be making deep noises over bumps? n how do i check? thanks all help is much appreciated

no idea how to check engine mounts.......they don't really go out. But if you ruled out suspension, and this noise only happens on bumps.......could be them.

-check your steering rack. Pull off the plastics that cover your battery and brake fluid. Look on the bottom for two 10mm 10 point bolts. Make sure they are tight. That could be the cause of your noise. The rack hitting the bottom of the battery area.

What!? Motor mounts go out all the time. I would check that along with the snub mount, the mount in front of your engine, and the bolts on your control arms. If bolts are loose, it can always cause a banging, especially on bumps.

They go out that often for you? Wow.

You made it out like they never go out. It is an older car, and yes they do go out. Do some searching and maybe you'll learn it's pretty common.

fixing it did reduce the amount of clunks in my front end some

btw, I didn't break it, and surprisingly it drove pretty damn well with it broken
