Strange error code after injector replacement.

So BMW replaced 3 injector due to misfire in cold conditions. Now wanted to reflash my car with the cobb but decided to scan for code prior to doing it. Following error code are pulled :

H2F83
H2F84
H2F81
H2F83
H2F84
H2F81
H2F83
H2F81

They appear as following in this order with repetition of some code. Intried looking these up with no success (no description in cobb neither). Should I be worried ? What are those codes ? As we speak car is on stock mapping and cobb is uninstalled from car.

Thanks for your help !

They are all history codes, hence the "H" in front of the numbers. I'd just clear them with the Cobb (before installing) and see if they come back.

Thanks a lot was wondering what H error would mean. Did a reset and couldnt see them back. Flashed the car back and probably wont come back.

Good stuff. FYI, if the code is current it will start with a P.
