Have all these things except the aftermarket intercooler and haven't had any issues going in for service. Of course I haven't had any problems with those areas of the car either. You may have some issues if something goes wrong with the powertrain (i.e turbos, wastegate replacement,...etc). Other people have run into some trouble.

I thought there was a same exact thread regarding the same exact issue yesterday that I posted.. talk about dejavu..

Well.. I'll say it again.. it depends on the dealerships and the service advisors/techs whether or not they allow you to install aftermarket products in your car. I can tell you for sure, that intakes are safe due to the fact that they don't cause anything damaging/significant effect to your engine. I always had my BMS intake installed for oil changes, alignment, etc. But, for example, you go limp mode/CEL and take it to the dealership regarding the notice, then it is recommended that you take off your intake. Some places have a policy where one will not work on your vehicle when there is a foreign part installed under your hood. Therefore this applies to the rest of your aftermarket parts that may be installed in your car.

They might not say anything about it, but trust me, they take notes and record it in your personal car profile that can be accessible to all certified BMW dealerships.. and when your turbo/fuel pump/transmission fail, they will most likely blame it on your aftermarket exhaust, DP, etc.

Oh, and not even going to get into turbo tuners.. you know what to do.
