Well, I had a 2017 m240i xdrive engine replace under Dinan warranty. My cause was because the turbo self destructed. Both Dinan and BMW told me it was a freak event. This happened with Dinan stage 1 V1. My car was a 2016 Aug production, maybe it has something to do with that. Now on a 2019 model year engine, seems to be stronger in stock.
