Why do some codes work and other dont?!?!

Hey everyone,
Been doing some coding for a while and for some reason some of the codes when switched dont work. For instance, I coded a car yesterday, went to go do the key fob windows up, went to the correct module, and when i read the ECU it already said it was activ. It wasnt, so i coded it back to nicht activ, and then back to activ. Still no good.

Disabling the car "BonG" has not worked on any of the cars I have coded.

Anyone else experiencing this?

I haven't had any problems, all the options work for me.

For the window/mirror with keyfob, you need check both of the komfort... options in that ECU. They are right next to each other. Also check the spiegel option in the NFRM/FRM2. I believe both need to be set to for all of it to work.

Yeah, me neither - it sounds like you just weren't paying close attention to the steps as you were going through and simply forgot to actually write the MAN or something.
