Hi All,
I have an 03 plate T30 X trail,2.2 DI, with twin suction valve type injection pump,
I have replaced the valves, does it need a re learn ? If so how do I do it,
I have read a few versions on tinternet to reset pump and get mil light flashing on the dash, but none have worked for me.
I had a garage stick the diagnostic machine on , and that showed no faults or anything strange, but not sure if it would talk to the version of consult needed ?
It has a flat spot /low torque below 2000 , after that goes like a train, nice clean , no smoke, but the low torque at low revs bugs me..
EGR has been blocked and engine breather re routed to keep things clean,, :biggrin:
Any advice please....

No relearn required, most like fault will be the injectors slightly blocked,
I had the same or similar fault that the car didn't pickup smoothly at low rev's noticeable 1st 2nd gear, if you put your foot down it would go like the clappers, the other issue i had was when in 4th 5th or 6th gear holding a steady speed or rev range the car would seem to miss fire again put your foot down and away it would go?
So I've recently added a full bottle of cleaner to a low tank and driven the car on high rev's on A roads / motorways and it seems to have cleared my fault?
But i only drive it on the weekends and not fully tested it as yet.
