Guys I checked the ECU on the girlfriends EK4 a few mins ago but it was not the CEL that did the flashing.... it was the ABS!

Is this the same?

Also I got 61 16 and 18 I'm wondering what the 18 is for.

Ok so I got O2 sensor and Injector codes.... what would you recommend be the first things to do short of replacing the 02 sensor, and getting the injectors cleaned and checked?

Just unplug and check connectors are clean and reconnect?
