I think it’s full lock your wheel is hitting the inside and making a bang sound I had a same problem and got smaller width ratio on my wheels and got no problems bro
I aint got none of the issues you mentioned on my MK5. But i got water leaking into the boot! I real paid to deal with. Either coming from the brake light seals or the vents behind the rear bumper.
I haven't got that issue. But I've heard it's a common fault in the Mk5 to leak through the tail lights. I recommend taking them out, cleaning behind and re-seal them back.
