BMW CBS Maintenance with MODS?????

yoon_209 · 07-25-2017, 01:54 PM

I understand the whole warranty and mod issue.

Can BMW deny you CBS maintenance service due to aftermarket mods such as Catless DP, CP, FMIC, Tune?

I have parts coming in the next week and a 30K CBS service.

I'm wondering whether its best to wait until after the service to install the parts or still get the service with the parts installed.

Anyone have experience with this?

If your dealership is "mod-friendly" (some are very friendly), then no problem. If a "stick in the mud", they will do the services, but will likely make noise about the mods, especially the 'tune" and, like some dealers do, will mark your record in case it comes in for some issues for systems associated the the mods.

Best bet is to get to know your SA and his/her thoughts.

Regardless, I would wait until after the upcoming service is done to do the mods. That gives you time to foster the SA relationship.

Just my $00.02
