What kind of problem mate....?

I have a BMW e46 on a 52 plate which i am trying to change mileage on, I have saved data from the original 35080 chip and then done a full write to a new chip then changed the mileage and soldered in new chip when powered up dash comes up code where the miles should be. If i solder the old chip back in it reverts back to the original mileage. I am using the "china" tacho universal. where am i going wrong? thanks in advance.

You have soldered it back to the original pads.....? Coz there is an extra set... Very close to the original ones ....:questionmark:

Post dump from original + the one you programmed mate...

CODE usually means that its looking for the CODE plug ...which it does not have....
