Hi Everyone, everytime I take my 2014 A4 to the automatic car wash, the wheel that goes on the belt conveyor tends to squeak really loudly as the car passes through the wash. Today the wheel also vibrated violently it was quite weird.

I never had this problem with my previous car before. I also had A4 in neutral as instructed so I don't know what happened. My car drove fine afterwards, should I be concerned?

I assume it's a quattro. You shouldn't take it to a car wash where the car gets dragged through. You can damage the quattro system that way, specifically the center differential. It's mentioned in the owner's manual that if you take it to an automatic car wash, then one where the wash moves around the car and not the other way. It's the same reason a quattro must never be towed and always be put on a flatbed.

Thank you yes it's a Quattro, I will avoid going to the car wash with the belt conveyor system in future
