It is never ending was hoping that valve was the reason there's no boost below 2k nut sadly not.
It's not only cars though, my front door lock failed with the door locked. If it's not one thing it's the other.

no low down power have you tried pulling plug on the maff sensor and driving up road see if sorts it out if it does then maff sensor. also on turbo vnt making the rod shorter should bake car boost sooner ie should be set to neg vac 15psi ish but it seems some react better with a higher figure,, this wont effect the level of boost thats controlled via the ecu via map sensor. both my clubmans had turbo's and dpf done and both made good low down boost,
i know bloody cars i have to go through mine soon see what it needs starting to feel some slight slack noises in the running gear looking forward to that,,, not,,, as when i start i always end up doing it all as like that new car feeling you get after for a while

I haven't tried unplugging the MAF but have adjusted the actuator length between 14 &17 on the hand pump, drives a lot better at 14 can't remember if that's shorter or longer. Will try MAF next but have to sort a which wheel bearing needs doing on my Astra and the coolant leak on the Mrs R50. Really don't have time to work as well
Cheers Stu

Had 10 minutes spare so unplugged the MAFF. Pulled better low down but struggled to rev. Connected again and drives better than before but not what I would expect. Is that the car relearning ?

yep its car relearning just gave the ecu a nudge as such, i would guess form that the maff sensor is at its end of life, they seem to get around the 60k and just go out of spec as the hot film inside gets dirty and corrodes a tad it changes the resistances,,

the pain in arse bit is they are not that cheap for a branded one thats needed, i have tried many cheap ones over the years and they never last of turn up plug in and car stops running very well,
febi bilsteen do a fair price ok one, bear in mind everything the engines does is based on the reading this sensor gives as its the beginning of all as such, after fit new one just reset the adaptions in the autocom ie everything except the dpf filter stuff on that screen
genuine peiburg sensor
