Have heavy noise and vibrations under the car , an V8-92 4,2 aut.
Sounds as a hammer drill and the vibrations feels under the feets. Sounds as it comes from the middle under the car.
Comes under heavy accelerations from low speeds. Follows engine revs. , not car speed. Is worst when car is cold.
Exhaust , original , is in good condition and is not touching anything in the body. Have checked engine-gearbox rubber brackets by lifting engine-gearbox and they seems to not be broken ( found two at gearbox , looks like hydraulic cylinders with rubber boots , two att engine , standard audi type , and one over the alternator. Missed some one ? )
Last months it has smelled rubber after driving car , but the smell disapear so fast after stopping the car so I am not able to locate where it comes from. Don´t know if it has any relationship with the noise.
