Wondering if anyones had this before? 
2011 meriva B (1.3 cdti) CD400 with GID, 
always been getting the following code on the radio: U0074

The other 2 codes are for the IPC, as im still messing with it...

but i was getting that U0074 code when i only had an op-com for diagnosis, so it's not the clone tech2 giving a fake code, and i was getting it before i ever touched anything electrical in the car.

The Tech2 gives an option to do a can bus re-learn on most module

Hi. I have a problem. I need to re-learn headlight control module (Bi-Xenon). When i try to learn it in GDS2, i get error "Device Limits Exceeded". What am I doing wrong?

Is anyone in the North East that is able to do a Brake Pedal Position Sensor Relearn?
