Hi guys, hope you’re doing well.


I have F10 535i 2011 126k mile on it.

The car runs idle with no problem, acceleration is quite normal with now issues, but on the highway at speed of 80 mile/h and more i get the massage of drivetrain malfunction and the car limits the power!!!! When restarting the message goes and runs normally until i reach the high speed and drivetrain malfunction pops up again…!!!

1- I have brake lights on the dash as i change the sensor but still not reset my front brake pads.

2- i have check light on as on diagnostic i found it catalytic converter efficiency below.

Note: below the speed of 80 mile/h the car can accelerate normally without any problems.


Plz help to recognize what’s wrong, i try to reach a spot diagnosis.


Thank your

Update: upon diagnosis i found the code that

1- charging pressure control plausibility too high.

2- charging pressure control : switch off as consequence.

Anyone help !!!!

You need to check the manifold pressure sensor.

How come this sensor cause this problem?

It can also be your boost solenoid, that a possible culprit

I have an N63 doing the SAME THING.... normal acceleration in lower gears, but at higher speeds where you spend more time under high boost, I also throw an iDrive malfunction, but mine is logging 102302 (MAF sensor)

I swapped the sensor banks & the error stays on that bank so it ain't the sensors.

Curious to see what your issue is!

Boost selonoid, check for it first

I have that error, isn't it realated to having the ewg actuator adjusted or replaced to fix?

just ordered a pair, thank you will give it a shot & report back

I was also going to report I have a similar issue. On highway under WOT around 90-130mph i get the same. I checked the codes and get an overboost code. I have yet to figure out the fix

What are you.. PWG or EWG... could be your wastegate is sticking just for a bit... check solenoid? PWG hose pinched maybe

[DementedF10]

PWG on mine.

is your charge pipe ok?

I saw these b4 wit WOT car feel good just driving normal, a new set of NGK's and the proper gap i have been boost'n since, now i keep a set just in case on the shelf. I might can find it on my MHD code history.
