BMW N54 - CODE 0030EE

[DSC]

BMW N54 .

CHNANGED 1 X BOOST SOLENOID . CAR WAS AT CODE 0030FE (OVERBOOST) TO NOW CODE 30EE UNDERBOOST .

I HAVE CHECKED VACUUM LINES FROM AROUND THE SOLENOIDS AND BEHIND OIL PUMP .

ANY IDEAS WHY WITH SWOPPING 1 X SOLENOID IT GOES TO UNDERBOOST FROM OVERBOOST ? NO (LIMP MODE) 3100 CODE WHEN HALF ENGINE LIGHT COMES ON . STILL FEELS STRONG BUT LIKE 50 % POWER ONLY .

You probably mean water pump?

Do you check vacuum lines to canisters and also vacuum lines running over tappet cover?
