Hello,
So I'm driving around today in my 98 SLK 230 and have the check engine light pop up on my dash I drop by my local auto store and they run the OBDII for me and come up with error codes P0803 (Upshift solenoid Circuitry Malfunction) and P0410 (Secondary Air Injector System). Now I have read about cleaning for the error P0410 but couldn’t find a clear post on where the items are located. And as for the P0803 I was unable to find anything at all. Any additional help without having to drudge over to the mechanics would be greatly helpful.
I am handy with tools and would like to take care of this myself; unfortunately I am unable to find any sort of shop book for my car yet.
Thanks,
J
