Are there any common problems that could cause the secondary air injector error? Cost of parts?...etc. Any feedback would be greatly appreciated.
Thanks

Replace the purple relay first and see if the pump still works. If so, you got lucky and get a fix for $25 bucks. If not then replace the pump. Mine cost about $500 from MB. I fixed it myself in about an hour. Note, the smog pump only runs on a cold start for about 60 sec when the systems are all normal. It helps to oxygenate the cats in the exhaust.
When this triggers, a yellow CEL lights up on the drivers instrument cluster. You can reset by removing the neg battery terminal for about 30 min. If it popps up again, you need to fix. However, this particular malfunction will not harm the car. But if you do not fix and reset, you will never know if/when something else malfunctions. Mercedes is highly digital and monitors nearly everything on the car. Even little things like a burned out bulb. The yellow CEL, means you can drive it but need to check and repair. HOWEVER -- The RED check engine light, means STOP, and call a tow truck.
Those secondary air pump issues are a common and minor failure item on several MB's. Not to worry mate

As stated above, I got the secondary air injector error which my mechanic cleared.
The part numbers on my receipt were 000-140-42-85 for the pump and 002-542-26-19 for the relay. Dunno if those are internal numbers or not cause I usually thought all our parts started with our chassis number 203.

link146 - in case you are interested - here is a thread with a fair bit of information on the secondary air injection pump / relay failure, the corresponding TSBs, and a cheap fix (if you are inclined to do so).

Thanks. Already found that thread and have since diagnosed the problem. The pump is definitely not working. Weather it is a bad relay or not, i don't know. There is only one way to find out....
