Engine malfunction , power reduced

Hello fam,

I started my car yesterday morning and i went outside to get something from the trunk while the car was idling, and suddenly i felt it shaking and i heard that annoying error bell

i looked and i found this engine yellow sign on the screen and on my idrive it says " engine malfunction, power reduced "

I shut off the car immediately and started it back again after few mins and bam error was gone and the car is fine since.

I searched the forum and i didnt dind anything, maybe i couldn't search properly because i am new in here. if there's a thread please point it to me

Anyways can you tell me if there anything to check or maybe the computer is still throwing stupid error since i didn't have the chance to replace my battery yet ?

I have an appointment on Saturday to have the battery replaced with an OEM one so i hope its a battery thing not something major.

Hopefully the battery will fix your problem. While you are having the battery registered, ask for a list of any codes. This way you will have proof that the car has any problems.
