Hi All
 
	 
 
	I have a problem with my Jaguar STR 2007.
 
	 
 
	I am now on my 2nd replacement auxiliary belt as every time it is replaced after very few miles it is "shredded" and breaks.
 
	 
 
	As I understand it the belt tensioner has already been replaced in an attempt to fix the problem.
 
	 
 
	I was just wondering whether anyone could give any advice with regards to fixing the issue?
 
	 
 
	We have run out of ideas of what to check next.
 
	 
 
	Thanks in advance.
