Aux belt can sometimes get neglected, what looked like healthy belt from outside once removed revealed potential issue, Gates Micro V after 26k
Yeah I'd definitely recommend they are changed often, mine snapped years ago damaging fuel lines causing a fire, and one of the German teams lost a VLN racecar due to the same thing
My aux belt looked like this after 41k! I can only assume never changed until I had it done earlier in the year (it’s a 2010 car)
