thanks guys

saw the mechanic / friday / who has worked on the car for the past 12 yrs

he told me the noise is the air pump and is working as it should

he put a new air pump in 4mo ago / he said it didn t really need one only new belts / which he changed as well

he said if the car sneezed the last owner had it fixed


MikeTangas / u hit the nail on the head

again thanks people / i'm new to the mercedes / the engine is much different from anything i have ever owned

nothing like the old english cars

does ride similar to the volvo p1800s i had
