Re: BMW 120D 2.0 2005 - Poor performance until 3000 rpm (waveforms) #

Thanks for the replies, I disconnected the IMV and still had the problem; and watched the turbo actuator and it's calling for full boost all the time the performance is poor (It's an electronic acctuator), the pressure regulator is I think a possibility, but I dont have a blank valve to confirm it or one of those new remote pressure control units so it would have to be a guesstimate, the weird thing is the live data pressure demand is following the actual pressure so it suggests some other fault; although I'm not a avid fan of live data. The AMM is a new geniune unit (digital type) and to have identical problems with new and old is not probable; but as we all know not impossible. I'll post the results of a new pressure reg when I get it. Thank's Mark
