Alright, i've checked under the hood and there's no LED thingy in there. I live next door to the mercedes dealer, i will talk to them maybe tomorrow and see what they charge to read out the codes. But it seems like everything points to the MAF. I think i'll try to clean it tomorrow with the CRC maf cleaner as the wires is intact before i go to the dealer.
Best regards.
