I just picked up a 2017 Countryman S All4 last week. It's my first Mini and still getting used to it. I noticed on startup there is a very quick squeak/chirp. It sounds like it might be the belt having a quick slip when first turning over but wasn't sure if the sound was normal. Wanted to see what you guys think. Video attached below, you'll hear the chirp right as it starts:

 

Not sure if this thread is still watched or not but Im looking to do this and would like some help on how to get it done. If someone who knows how to do this would please DM me that would be great. Thank you!
