But where i live, most of my driving is in traffic jams and is uphills (not lots of miles daily but so much heat from uphills and traffic) so 5000km changes is affordable

That's interesting. I don't drive my E90 much anymore, only on the weekends. I'm curious what my head will look like when I remove it for MILVS in a few months.
