The term "Intake Slide" is new to me but due to the price I presume they are talking about the Throttle Assy or throttle Actuator.

On your car you probably have ASR. If so you also have EA (electronic accelerator). This is basically drive by wire (although there is real wire (cable) to back it up. When MB went to EA it made it real easy to incorporate CC and ISC within (Cruise Control and Idle Speed Control). The earlier forms of idle speed control used a separate intake mechanism for air flow at idle called an air slide. It was called that because instead of acting as a throttle (a rotating flat plate in a round bore), it placed a sideways slide to control the airflow. I presume that someone has combined the terms not knowing where they come from.

Anyway, the throttle assy is a gathering of motor/gearings and electronics that allow precise positioning of the throttle plate. This was a common problem in those cars. The replacement is a redesigned part and the previous failure bears no significance to furure problems (IMHO).

Don't think this is the throttle actuator since that too has been replaced at a cost of $800. Maybe part nos will help:

Gas Actuator 141-73-25 $790
intake slide 141-89-25 $801

Aagins, thanks for the help in advance.

Arif:
What Steve means is that Mercedes don't have belts, they have chains, which per Mercedes have no replacement interval, although there is many opinions on actually going ahead and replacing them anyways. Failure is quite rare of these chains, with a few exceptions, and your 119 engine is not one of them.

I have heard the throttle motor assembly called several names. Unfortunately they were both mentioned in your list, Arif, both gas actuator and intake slide. I wonder if one of them was an incorrect part and should have been deleted? Maybe Phil at PartsShop can help identify these part numbers.
