My 2016 BMW i3 REx was recently due for its “big” service. I bought it here in the UK in the summer of 2019 when it had just turned three years old; almost certainly after finishing a lease. So this year (2020), it’s supposed to have its brake fluid and oil changed, as those are due every two years. This is a service for which the local BMW dealership wanted to charge me several hundred pounds. However, the car is out of warranty and I like to be self-sufficient, so I gathered the tools and information to do these jobs myself. Here’s what I learned and some of the costs I incurred.
I hope this is useful to others here. Please feel free to share on other i3 group/forums.
