Question about W204 2010 C300 4matic sport Code P0410 88K miles
Hello, first post here. So I was literally going to get an inspection sticker the week my check engine light came, just awful luck. My Benz is a 2010 C300 4matic Sport w204 making 2024 the last year in my state MA that would fail me for an emissions CEL (cars over 15 years can pass with emissions CEL). So I get 1 code P0410 secondary air injection pump.
First thing I check is the fuse and the fuse is blown! Could I have lucked out with just a fuse? I put a new 40 amp Maxi fuse in. My question is now, will my CEL shut off automatically if it is just was the fuse that was faulty and if so, when will the CEL turn off? Do I have to drive it a certain amount of miles? Would unplugging the battery turn the CEL off? Also, if the fuse was blown, should I replace the relay too? What would cause the fuse to blow, is there an underlying problem?
My secondary fan was making a loud jet engine whistle before on cold start but now its not.
Any advise or info would be very helpful. Thanks!
