hey guys can you tell me if you go into your dealer with these in and if you have any problems with them?

fmic: yes or no

catless downpipes: yes or no

jb3 (on valet mode) : yes or no

dci: yes or no

Nobody can tell.

Build up a good relationship with your dealership and create an overall win-win situation for BMW and yourself.

e.g. when you bought a couple of brand-new, well equipped BMW's within the last years, nobody will claim about a set of turbos which have to be replaced on the early build 335i anyways. It's up to you.

Cheers,
Eugen

Depending on your dealership, you can get away on certain aftermarket parts. Definitely, not Dps. To be on the safe side, remove all aftermarket parts before bringing in your car for maintenance if you value your warranty.

dont think that's necessary unless they're doing some engine work...otherwise for scheduled maintenance pretty sure you can leave all those in without having to worry about anything..
although i would recommend getting the BT tool to clear codes from the JB3 after you put it in valet
