I have a 2007 BMW 320i Auto. The check engine light came up

Customer Question

Hi, I have a 2007 BMW 320i Auto. The check engine light came up the other day, I scanned with an OBD scanner and got code P122F and C0700. Can't find anything related to these codes online, any ideas?

Hello

that P122F code doesn't fit the regular code standard so I'say that this is due to reading the codes with a generic scan tool - typcially a genuine BMW scan tool will give more accurate reading as well as providing what the code means

also the the C codes relate to body modules, which are not covered by any standard so won't be able to be read off with a generic scan tool

unfortunatly I;d say this is going to need a trip to the dealership or a BMW specialist whom holds the BMW diagnostic tool

sorry its not a more DIY answer

if you tell me how the car is driving with this fault I can try to provide further help

Hi
Thank you for the reply, the car is driving without issue or cause for concern.

Hello Parmjit

in that case if the car is driving fine but displaying an error code its likely to be something small like a power steering switch or air temperature sensor

both of these ( and there are many other small possibilities) do effect how the car drives but only in a very minor way so the lack of their input isn't really an issue in everyday use

If you are concerned about it then its going to need plugging into a dealer level diagnostic machine to obtain the codes and identify the faults
