Hi all, replaced the hpfp tappet in my cupra today , in order to remove bottom bolt on the pump, rather than removing the Schrader valve fitting, I removed the housing itself with the sensor plug on (2 x t25h bolts). Once opened I could see inside there was a swashplate type washer , all was refitted ok and all working fine , tappet showed little signs of wear but replaced anyway to be on the safe side , my question is as I removed this, is there any kind of relearn the pump needs to have done via vagcom etc, or is all well, car runs fine with no warning lights etc.
Thanks in advance.
