Secondary air pump (smog pump) C Class
I seem to remember sometime back a topic on how to repair or check a the secondary air pump for a 94-00 C Class. I've searched but not found anything specific to this.
Has anyone successfully tried repairing their smog pump??

Its not working. Check engine confirms it on DBII scan. I realize its not a necessary part for the car to run but I thought I would look in to it at least.

Yeah, mine would blip-whistle a few times at normal op temps at stoplights. Engine would rev up and down a little, but it did this for probably 90k miles with no other problems caused. I sold it as-is. I think the part is several hundred $$$

If that's the engine-driven type (belt drive), about the only thing repairable is the clutch, which about 1/2 the time is the problem, and is I think the only available repair part for the pump.
If it is the electric motor type, never heard of anyone fixing it, but wouldn't hurt to try. Gilly

I removed the smog pump from the car this weekend and examined it today. The fan was a bit hard to turn. I put a few drops of synthetic oil (used Mobil 1 differential oil ). Let it sit for a few minutes and now it twirls with no resistance. Hopefully, thats whats wrong. If that was all it is, then theres the fix. I'll update after I put it back. See pics:

So that's what it looks like! Like Gilly said, some of the older cars have belt-driven ones - I'm not sure if that means older 202s, or that after that 201 they became electric. Obviously your 96 is electric......and therefore independent of the belt.

I think the early 202 was still a belt driven air pump, not sure when they went electric. I do know the ones with the Kompressor motor have no air pump, it uses the supercharger for that, using a divert valve.

I put back the pump last night, drove to work, check engine has not come on..... so am guessing it works. Right after I put it on and b4 putting back the undercarriage cover, I started the engine, crawled under the car and checked if I could hear the pump run. I could not hear anything but not sure if I am suppose to.
All I know right now is that the check engine light does not come on anymore - at least not driving to work. Update: CEL has not come back on.
