So one of my neighbors here just about a month ago lucked up and got a 2012 Volkswagen EOS Komfort convertible just like mine. But he is having some issues and can’t figure it out. He doesn’t really do Internet so I thought I would ask here for him. For some reason he can put brand new spark plugs in there in the cold packs and after a couple of weeks he can pull the spark plugs and they’re all corroded and sometimes has oil on one Of them. He is replaced them and just checked yesterday and they are the same way again. Anybody have any suggestions why? Also he has an OBD two reader and for some reason it keeps saying his IAT sensor is high. He’s already replaced the IaT and has even replaced his mass airflow sensor. But it still gives him the same readings. Yes he has cleared the codes on the OBD reader and on the dash of his car but the check engine light will automatically come back on, he does a new scan and it says the IAT sensor is high. Any help or suggestions in that department would be awesome and ever so thankful to please.
