Just so I'm not losing the plot but I could swear my GLC 250D has started making what I can only describe as a whir noise on a cold start up.
It only lasts for the first 30 seconds or so of driving and only on a cold engine. It's pitch increases with engine speed.
The dealer changed the aux belt on Friday however I can still hear it?
Or can I?
Link to a short video. I can hear the whir noise after the 2nd rev of the engine. It's more noticeable on driving a slow speeds.
Any ideas or have I just gone nuts?
