Good Day


I see you have an unusual configuration compared to the vehicles that were marketed in the US. Your engine is probably fitted with a semi-independent ignition system commonly known as the EZL. If this is correct than your engine may have a distributor cap mounted to the front and is fitted with the KE-Jetronic fuel system, commonly known as CIS-E. I believe that engine configuration was last offered in the US on 1992 cars, mainly the 300-SL and 300-CE. I am also of the belief that your chassis number was not offered in the US.

I can only speak from my knowledge which applies to US vehicles and 1992 was a big year for several changes with MB in the US. One change was fitting A/C systems designed to operate with R-134a refrigerant. I have no knowledge of the engine and chassis configurations that are, or were available in Africa so your vehicle may have been fitted with R-12 from the factory.

Now let us explore what ails your A/C system. Behind the battery there are several control units/modules. Does your vehicle have a module called the MAS unit? It will have a knob on the top that rotates to lock it in place. Or does it have a KLIMA relay?


Once we establish which A/C compressor control system your vehicle is fitted with than collectively we can begin offering diagnostic suggestions.
