What faults were you getting, I have 00310B: charging pressure control 2 plausibility / 0030FF: boost pressure too low. I'm about to change both valves. Hope it's not the DME
Yeah I have, trlurned out to be the boost solenoid valve. Changed all the vacuum lines as well the were bad. It was all good after, they are in a very tight place to get to, the one for bank 1 is behind the passenger sideheat exchanger.
Hello, what kind od error do you had ? I have 120208 pressure check, boost pressure to high, new turbos, new wastegates and blow off valves, check vacumm lines and no ideas
I have 2013 Bmw 550i after I did valve seal job I notice my car have too much negative pressure to the point when car is running its really hard to take off oil fill cap. I replaced oil separators under valve cover PCV is almost new. What can be malfunctioning to create this much negative pressure? Thanks
@@Logic7repair No errors it’s running great. I’m concerned I will blow out rear main seal or front seal. I never noticed that much pressure on any cars I had before or worked on before. I know there should be some negative pressure but I just do t want to create more issues.
@@mikimiki195 Did you replace the pcv hose? If you did was it replaced with an original part? If not that would be the answer to the negative pressure.
Hello. I have the same engine N63. I have the charging pressure control deactivation pressure build-up blocked 120408 error. 1. Since it didn't specify as bank 2, does this mean a problem with the bank 1 components? 2. If so, could it mean that the boost valve for bank 1 is faulty and is allowing a constant flow, which implies an over boost on bank 1? Please help.
What’s the name of this part for 2019 bmw 750i I’m having the same issue getting codes for high boost pressure

Have you sorted it?

Is removing the under tray necessary to remove/ replace boost solenoid

Yes exactly the same error, most likely dme problem
Where does this solenoid sit, on the side of the intercoolers?
Passenger side, 2 solenoids there
Id assume you'd have to remove the intake the get to them @@Logic7repair

That is normal there should be vacuum in the crankcase, if it runs good and no errrors you should be fine

@@BishopBible yes everything was OEM
What was the code? I have p0242 only appear after 4-5 rpm

What possible ways are there to fix this? I think I may have this issue. How bad is it to drive with that issue?
Replace solenoid, if problem still there it’s DME ecu
I would tie the circuits together, only using bank 1 circuit
Technically not the correct way but I like it! 😂
Thanks
