ML-350 4-MATIC
[Update] Weird noise whining on morning startups (with sound recording)
Hello everyone,
I have a 2009 ML-350 4-Matic that had done 102.000km and for a week now I have been hearing a weird whining noise when I start the car in the morning when the engine is still cold.
The noise goes on for roughly 90 seconds and then goes away.
Is this the belt acting up on me? Even though I just changed it about 5 months ago? Or is it just the morning coldness's fault?
I have provided a sound recording down below.
Thank you in advance.
