Hi Guys,
after getting my car back after having the valve stems replaced and turbos changed the second turbo isnt working, so anyway.
when on boost the first turbo pulls to 0.7bar then as soon as the second turbo should kick in it looses boost. The boost drops to around 0.5 the slowly falls the higher in the revs it goes.
its probably a problem with the wrong hose on the wrong place or something similar, could anyone shed some light please?
ive been studying the sequential system problems as much as possible, its asif the EGCV isnt opening.
the car boosted fine before the turbos where changed, only reason they were changed was due to the oil seals leaking, so all the actuators functioned properly before.
Thanks
Jonny
