HELP - W204 1337 Code
Hey all,
In a bind. Getting a 1337 fault code on my 2010 C300 Sport 4MATIC. My check engine light was on, I've had the alternator replaced and the code comes up immediately on startup after being cleared. Also showing is a P1897. It looks familiar to the issue here:

My very limited knowledge is leading me to think it could be that PREM AIR sensor, as I have after market HIDs installed that I got from aznoptics here.
Any help would be greatly greatly appreciated.
