It seems my servicing (by the last person) has been done in the wrong order What do you think i should do? They have doen the following
P1, P2, P1, P3, P2, P1, P3......IT SHOULD HAVE BEEN
P1, P2, P1, P3, P1, P2, P1......So i thought i should do a P3 next but since this was only done last year, should i do a P3?
