you can just about make out what sounds like maybe an air sound That sounds cyclic as its on a Rhythm. I wondered if it was coming from the water pump maybe. Really hard to tell I think I might have to get it booked into a dealer as it’s worrying me it might be more significant in the drive belt etc,It's hard to hear a whooshing noise over that clatter.
Any updates on yours? As I have the same problem.I have the exact noise, any updates on the diagnosis/repair?
