Help with weird noise.

Good that you had that work done and brakes and tyres checked.

 

I'd not worry too much about that report, certainly not for now.

 

There are a couple of possible suggestions there that the car might have been given some minimum sales preparation or just happened to have some work done and after needed selling (which might be good or not so good as it seems).  Having three tyres at 6+mm and one at 3mm isn't an ideal scenario.

 

Do you have a spare tyre.  Take a look at all 4/5 tyres and note if the makes/models, dates of which tyres vary, as in that previous video or see here. - https://www.michelin.co.uk/auto/advice/tyre-basics/tyre-markings-explained

 

Did you follow the previous advice from others and me, found any more detailed service history on the car?
