    Hi there.

    Long time lurker, first time poster.

    I have a 2009 Gen II with 135k on it. Got it at30k from Hertz.

    Driving yesterday, Red triangle, check engine light flashed on, along with another unnoted light. Only the triangle and CEL stayed on. The a/c appeared to change to warmer, damper.

    Parked it.

    Tried it again today, triangle and CEL still on and constant. A/C appears to be working.

    Checked a/c charge and is good.
    Replaced the 12v battery within past 18 mos.
    Consumption display appears to show engine/electric/battery operating normally.
    Oil level is normal.
    No noticeable change in vehicle behaviour.

    O'Reilly's scanned the system and got these codes:
    c1241
    c1300
    P0A93

    Any ideas, please? Am I looking at a dealer visit or would a good independent mechanic work?

    Thanks very much for helping the newbie.

    Have you done the inverter pump recall?

    P0A93 is the invert pump
    that will cause the other lights and codes
    don't clear them go to the dealer

    Thanks! Found the recall you were mentioning. Have no recollection of receiving notice of it. I'll give the dealer a shout tomorrow.

    Cheers!
