Smog Pump (Secondary Air Pump), Fuse location. #31
First all, I would to thank everyone how wonderful this community has been helping me.
Recently, my 04 S500 4Matic troubled some P0410 issue. Sticking relay caused pump overheated and melt through housing. Replace pump and relay did not help. found out no power into the pump.
It must be the fuse or wire harness but can not find any information about the fuse.
Finally, the fuse ia been located. Is the Fuse #31 40AMP. not been listed on fuse & relay chart nor the W220 Wiki.

Why didn't you just remove it and code it out with either a scan tool or star diagnostic. Secondary air pump doesn't do much anyway. You might have to block off the egrs. Both very useless things. Just get rid of them
did a secondary pump recently and it was completely full of water can you imagine that. it sucked water in from a gap in the foglight area i am thinking, kept pushing water up towards the engine (through secondary air hoses) and luckily did NOT
