So my question is if I go in for service and I take out the jb4, will they not be able to detect it? My purpose is to protect my warranty. This is for a f30 335i

The JB4 N55 Stage 2 has the code deletion. Unfortunately only Stage 1 works with the F30. You'll have to purchase the CAN tool from them to delete codes.

Thanks.

It says it is a "piggyback system" where scan tools cannot trace it?

^^^ Just curious why some names of companies are censored? Is it because you don't like them? Or is that just a forum policy?

I wasn't aware of the censoring, the forum automatically censors urls i guess

You can also use a BT cable to clear codes. They have the file for the F30 on their website for download. Of course, BT cable allows you to do many other things too; including read and delete "shadow codes". But, it's much more expensive than buying the CAN tool.
