I've got the dreaded P0089 pressure regulator code, i have changed the regulator, first with an aftermarket now with a genuine mitzy party, cleared the fault codes with an OBD READER but it still goes to idle after about 20 seconds.
This hasn't just appeared, I was reversing slowly and a telegraph post jumped behind me and I hit it (very slowly) and the fault appeared.
Anyone got any ideas of what else to look at?
Or what to try?
I've checked underneath and cannot see any obvious damage, loose wores etc.
