I have several issues with two separate vehicles. I have a code P0410 which indicates that the ECM could be saying the 02 sensor is malfunctioning. It's listed as a Secondary Air Injection System Malfunction.This is on my 04 sl600 v12. I just replaced the ignition coil and now this code appears. I don't know if I broke or disturbed a vacuum line. All suggestions are appreciated. Where is the fuse located for the pump?

On my 98 sl500 I am getting code P0701 it says it relates to the MAF or the throttle body. Is there any video on how to remove and replace these two parts? I would like to clean them before I try anything else.

I'm super old, but I'll give this a stab.

Just Google what you want to do and when you find something that relates, watch it.

Understand the google response. I have done that actually, I hadn't found one specific to my model. Do you know the location of the fuse for the pump on the V12.

Fuel pump?

In the trunk. Green block fuse.

Your avatar sez W140, so here you go.


I sure hope you are 60 or older.
