Ask a Car Question, Get an Answer ASAP!
Hello and welcome! I'm Billy and I will assist you with your inquiry. I understand that having car problems can be frustrating so please feel free to ask if any further info is needed. If you get prompted for a premium service or a phone call, please ignore that, cause I don't think it is needed at this point. My apologies for the delay, thank you for your patience. May I know your first name?
The engine control unit defaulted to limp mode when that happened. This is caused when this unit detects faults. If the faults are not continuous, the message will go away. However, faults will still be stored.
If the problem happens again, you will need to connect diagnostic equipment to get the faults. If you have access, I can explain the faults, tell you what needs checking and how to check, in order to fix this.
As mentioned earlier, no phone calls are needed. This is an automated message by the system.
Most commonly on this model, the fault would be caused by a faulty mass air flow sensor. But we need to get the faults (only if the problem happens again) and we can proceed as needed.
Exactly. And it doesn't need to be the dealership. Any garage with some experience on BMW models should do.
Thank you for your trust Craig. Cheers.
