I have the same problem on my xc90 mk2 2018 - i replaced the left headlight with a used one and fitted the original light module to it but the daytime running light / indicator led module (led ballast) was physically broken - when i fit a brand new uncoded module i get similar error codes…. The indicator flashes normally but the dash indicator blinks fast as if a bulb is blown and the daytime running light doesnt work in that light - can this be coded to the car using vdash ?

I'm changed battery and error disappear. No resets or updates required.

If you want to get a CEM/VGM PIN quickly, you can contact me for a paid consultation.

If your car is connected to vdash and all modules are showing, you have to click on CEM or BMS. There should be something like reset Battery timer. But if your car is already an ICUP(Android Automotive) one. You need VGM pin for that.

@Kierzek vdash doesn't support your car.

@TomR what kind of adapter did you use to connect vdash. There are some really bad clones out there, that are known to create problems just by connecting them to the OBD-port.

@Bowtiekilla Try to read the car with VIDA. It's working with newer P3 models with a little knowhow.

@Brannon 5 cylinder petrol engines don't need injector coding.

Open the cab door
Put the brakes in D, then P
Release the brake pedal, repress the brake pedal, and double flash the lights twice in a row

Release the brake pedal and you will find the vehicle in second gear
