hi, so the car has no power feels like 318d with 100 horsepower.
INPA diagnostics won't show any fault
vacuum hoses were replaced last year

anything else to look for ?

Would Faulty MAP / MAF sensor throw a code?
would one of the actuator turbo valves throw a code?

would anything else NOT throw a code?

i think bmw needs better sensors to diagnose their shit too

thanks

I was going to say LP turbo issue, but you have no power through entire RPM range?

[bayerischer]

hey, yes, no power entire rev range, but it still pulls like 60%

anyhow, i just came back from INPA live code read outs, and this is what came up suddenly in german tho

4180 - DDE: Charge-air pressure actuator, activation

Sounds like a pretty severe boost leak somewhere.

4180 is a short circuit electrical fault for turbo control pressure converter. Either an electrical line or the pressure converter are dead. DPF regeneration is blocked with this fault. Fix it soon.
