REDUCED POWER

[DSC]

HI

STANDARD BMW 135I N54 . UNDER WOT IT KEEPS GOING INTO LIMP MODE ND LIGHTS UP DASH BOARD WITH REDUCED POWER .

CODES : 0030FE

AND 3100

ANY IDEAS MEMBERS ? I BELEIVE THIS CODE IS FOR OVERBOOST AND FOR LIMP MODE . WHAT CAN CAUSE AN OVERBOOST SITUATION IN A STOCK CAR .
WHEN CAR IS SWITCHED OF LIGHT IS GONE AND ENGINE HAS POWER AGAIN UNTIL THE NEXT WOT .

Take the car to someone that knows these cars to assist you. Its hard to troubleshoot a car remotely without a datalog but someone that knows these cars can check the obvious culprits...e.g. boost leaks...broken chargepipe...etc

An overboost condition/boost spikes/boost overshoot can also be triggered by a huge boost leak or general boost control issues on the solenoids or vacuum lines.

:fencelook: is the car def stock ? are you the first owner ?
check all breathing pipes (rubber ones)...they get soft with age.

Agree 100% on this

1.Vacuum seals.

2.Boost leak.

3.Charge pipe crack.

4.Waste gate broke..


I think no1 is most likely...

Hi

I have checked no boost leaks , no cracked pipes . However on the right side solenoid there is like a black cap that is broken off revealing a 3rd nipple on the solenoid . maybe this is the issue ?

Where are the vacuum seals located ?

1.Vacuum seals.

2.Boost leak.

3.Charge pipe crack.

4.Waste gate broke..


I think no1 is most likely...

car is def stock . I beleive its the 240kw 135i . some of the rubber pipes do seem soft . There are no leaks or visible cracks on the vacuum pipes
i believe boost leaks throw off a fault code as 0030EE . which shows under boost targets . so I doubt there can be leaks.

Is there any BMW SPECIALIST in durban whom can help ?
