I recently had the fuel system cleaned in my 93 190E 2.3 as well as having the EHA switch replaced. When I had this done, the mechanic informed me that I needed a new "air flow sensor" and that it would cost $875 for parts and labor. He explained that the part was $825.

Is it true that an air flow sensor costs that must? Any suggestions on where to get one at a better price?
