    Second yellow; that's not right in Germany in the winter; on the highway today at 0*C, 65mph, cabin heater on full my PEM temp was on the second blue but, motor and battery on first blue.

    I get to the yellow in summer at 40*C when I'm giving it some stick.

    hmm... I've used similar looking scroll fans in the lab. I'm not sure they're up to the road grime you'd pick up in an automotive environment. Is there an air filter in there somewhere?

    ## Battery issues notwithstanding, EVs appear to have very little mechanical troubles.
    {I replied}
    ...The AC induction motors used to drive many EVs seem to be highly reliable.
    D/C motors used in pumps and fans do wear out after a while.
    ...
    Overall reliability is only as good as the weakest link. It is a shame when the accessory items are the trouble spot.
    At least they aren't too costly to fix, and don't require tearing much apart to replace.
    The above was just a general comment about components in general. I have not heard of other owners running into multiple fan failures so soon after taking delivery.

    By the way, slightly ironically, I notice that my "Tesla Fan" logo icon stops spinning on this forum sometimes.

    (Local GIF animation playback issue with some browsers I guess.)

    Now i got the #1144 error-message again. I already received a new blower for the engine, maybe i will swap for the PEM instead. I only wonder, why those error only appear at temperature below -5° Celsius together with snow and salt-wet streets?. Is something wrong with those blowers in general?
    I know: "it never rains (snows) in southern california!"

    today I have to add : me too
    nearly same conditions, A61, snow fall, wet, -2C°. After parking and charging the car for about 4 hours => ID1144 +
    ID 269 and shut down while driving slowly.
    I was able to drive my car to my hotel, for now the error vanished, but I'm sure it will come back
    @eberhard : Is your problem finally solved ? what was the solution ?

    Geez guys, we here in Canada drive in these conditions all of the time...I've never seen an error message.

    Just curious, how far are you driving before you get these error mesages? (I'm only averaging about 40 kms / day).

    i carry a spare blower with me. i left germany 2 weeks ago to see elon musk and JB Straubel in Milan. then i drove to Spain. Just before Valencia the same. on the autovia i have to push from underneath, where the blower sits and he started to spin again. was fine for 2000km but now i just passed Geneve and its raining and snowing now. think will not take long now.
    on saturday i will charge my car in munic in the teslastore. hope they can check it.

    My daily average is > 150 km and today 360 km, odometer about 16.500 km, my guess, Eberhard is in the same range or more

    and yes I would fully understand if you as Canadian would call me a wimp
