Modified or Aftermarket and Free Scheduled Maintenance

I've searched and couldn't find anything on this subforum. The question is simple, will the dealer still service your car (in terms of free scheduled oil change / maintenance for 50k or 4 yrs) if you have aftermarket parts on your car?

Separately will they record modified cars and red flag for future warranty issues?

In most cases, yes. It depends what you have on your car. The tunes are the biggest factor IMO. Every time a BMW tech plugs your car in, all the data from your car gets sent to a main BMW hub. If there is something they see in the programing, like a tune, they will send the tech a email and it will automaticity void your warranty. So, it's not really up to the tech anymore. But, with all the other stuff, it is up the the service writer and tech. If I had a tune I would get it taken off before I went in, unless it's a Dinan tune.

Is warranty tied to free maintenance? Will they still change my oil etc?

if you flash back to stock can they still see that you had a tune and just removed it?

Yep. Maybe not your local dealer, but if BMW asks for the download to check for tampering before authorizing a warranty repair, they'd know for sure.

i had my tecnocraft FULL INTAKE for quite some time and it has been in service 1200m service 15000 and 30000 miles service no issue with the dealer. i am going back to get my rear cigarette ashtray replace (not that i use it but that thing wont open so ill have the replace) well see what happen. I also had my rear exhaust modded at that time and had no issue. now i have the AKRA i dont think its going to be an issue since i only have the SLIP ON for now. but to be honest no dealer should deny your warrant just because of an exhaust.

i have gone in fully modded for service and they only notice the exhaust. i usually do oil changes every 3000 to 5000 miles and car runs fine so far. try to get your plugs checked out around 25,000 miles maybe closer to 30,000 miles depending on how you drive.

i've gone for service with all the mods in my sig. So far so good. No issues to date. They still honor the maintenance schedule and any warranty issues. Mind u, i dont have a tune. But i have quite a number of other mods on my car.
