how to check if the k40 is fine
hi everybody ! i still have a esp ecu problem and someone suggest me to checking if the k40 relay have no trouble and if he deliver 12v to the esp ECU...if someone know how to do it.
i would like also to know how to remove the ecu safely.
thank you !

my car have power issues and lights of (abs esp bas) sometimes here and sometimes not, also my steering wheel is sometimes strong and sometimes not , the car running slugglish most of the time but suddently it can be a beast...
i Went to the mercedes dealer and they telling me its the esp ecu unit to change and that all those problem are related to this...
Put the mercedes diag i have those codes coming of the ESP ecu unit on
(C1149,B24/2,B34,A7/7B1) The voltage supply of the components has interrupt or short circuit
(mass air flow sensor already change still power issue)
cant it be a k40 voltage problem ? i suppose i have to check the voltage of the relay before changing my esp ecu
