    CLA 2014-2016 Squeaking noise, front passenger sode

    This noise is happening to the Mercedes CLA 2014-2016 models, does anyone know what is causing this?, the belt and idler pulley and Tensioner all have been changed and the noise still there. Please comment on the video if you have the same problem or know the solution. This noise is on front passenger side only when the car is warm or hot. Here is a link to a video I posted on YouTube of the noise. https://youtu.be/58dBHMlTLMM

    Anything funny near the water pump? Alternator?
    Might be a bearing somewhere ...

    To much oil at some point that messed up the crankcase ventilation and the engine has to much pressure in the crankcase and it is making the crankshaft seal bulge out touching the crankshaft pulley. Had this happen to mine. When it is making that noise take the oil cap off and the noise will stop and as soon as you put it back on it will start again.

    The dealer had to replace the whole pcv valve and the intake tube on mine. They have to remove the passenger hub assembly to replace the Crankcase vent tube. Here is a video of mine.

    Geewhiz I know these motors are touchy and oh so many items have to be within spec
    So these many reports of oil overfilling is disturbing
    If its the dealer techs they should at least do a cold stick check before releasing the car
    For diy its a no brainer to do that check anyway if not just to admire ones handy work

    I got an update, after changing the idler pulley and the tensioner the sound did not go away, I took my car to mercedes and they changed my AC compressor $2000.00usd including labor. and the noise has now stopped on my car, I will continue to monitor the issue but for now the noise is gone!

    Just based on the headline, I'd suggest: a gym membership for your wife?

    Forgive me, I'm a bad person.
    I took European Delivery and drove through four countries in my limited edition Universe Blue CLA 250.
