Relay chart or diagram for 2012 GLK350
Just replaced the secondary air pump on my 2012 Glk 350 and I still have an error on the dash! I cleared the code but it came back a day later! I have the relay from the dealer and guessed it was in the fuse diagram but of course it is not because that would simply be too easy! So I have the relay but it appears this could be one of the 7 in the fuse panel! Anyone know which one is the relay for the secondary air pump?

I'm just replaced my Secondary Air Injector, but also need to replace the relay and fuse. It appears that the relay is "P". Do you know which is the accompanying fuse???
