   Yup.
   
   
   VTR 3.5 bar - normally under rear bench, under plastic circular cover
   VTS 3 bar - normally on the end of the fuel rail

   there will be a reason you are getting flat spots, a higher pressure fpr may get rid of them but wont cure what was causing them in the first place.

   The one on my VTR was 3.5bar, and i'm fairly certain all VTRs were 3.5.
   
   When you look at them, they'll have stamped on the side what rating they are.
   
   300kpa = 3 bar
   350kpa = 3.5 bar
   450kpa = 4.5 bar

    vtr's are 3.5 bar. some mk4 golfs have 4bars on. merc bmw and maserati use the same style fpr aswell, maybe more aswell.
