My car has 44k kms and it's notifying me that the brake fluid needs to be replaced. It was previously replaced in May 2022 at 33.6k kms.
I don't drive often, but I live in the Pacific Northwest, so it's often rainy.
According to RealOEM.com, BMW has two part numbers for my car:
83132184843
Brake fluid DOT4 LV, low viscosity
1000ML, TU
BMW Group, EU
From:02/01/2010
To:-
83132405979
Brake fluid DOT4, low viscosity
1000ML
BMW Group, Japan
From:01/01/2015
To:-
I haven't found a specification for either of these fluids, so I don't know if either is preferable relative to the other.
Since I can get both from ECS Tuning or TMS, I was looking at ATE SL.6 DOT 4 ISO-Class 6 or ATE Super DOT 5.1. The former has slightly lower viscosity 700, as compared to 750, but the latter has a 3 year change interval, as compared to 2 years. I probably won't ever leave it in for 3 years, but it's nice to know it's possible.
Is there any reason to not use ATE Super DOT 5.1?
