Fan belt tensioner issue

[Rizwan Patel]

Hi new here thanks for having us. 

Got an issue on our 2.0 litre A6 c7 auto 62 plate

The fan belt started fraying little rubber bits so had it changed also changed the tensioner as it as moving when in idle.

 

Now the new belt in a brand and tensioner down same thing so chewing the belt on sides. 

Again removed then one one and replaced with gates tensioner and gates new belt and again 

 

Two questions

1. Should  the tensioner Havel little play or should it should I say

 

2. Also if so then why is belt having little bits throughout being chewed 

 

I saw a mates 17 place c7 facelift but his tensioner was not moving however looked little different

 

Or am I incorrect in assuming it's different.

 

On ours belts looks correctly aligned

 

plz see vid 

thanks in advance for the help

 

Thanks
