Intermittent belt squeal while manoeuvring

[Mkyw]

My 68 plate 199 has an intermittent load belt squeal noise when manoeuvring. I’ve had van for 2 weeks and today was the 5th time this has happened.
has always happened when turning in first or reverse I.e 3 point turn. Sounds like aux belt slipping?
I've read the posts on cam belt tensioner, but these are on older vans. Will get to Vw, but just looking for some info if people have had similar issues so I don’t get fobbed off with “ we couldn’t fault it” thanks

Possibly auxiliary belt, if it's mainly low speed maneuvering with big steering inputs it could be that the power steering pump is working hard and the aux belt is slipping trying to power it? I'd test that theory by carrying out the same maneuver on loose gravel, which should require less effort from the power steering pump.
Also try to see if the noise gets better or worse with AC on or off, the AC pump is driven by the aux belt.
