BM3 2+ Tune on 540i xDrive?
I was talking to a fellow Bimmer enthusiast last night about planned upgrades. I mentioned that I eventually want to do the BM3 2+ tune on my 2018 540ix, but he recommend stopping at stage 2. He said the xDrive front CV joints are a little on the small side and a stage 2+ would wear them out quickly.
Anyone have any thoughts on this, especially anyone running BM3 2+ tune on their 540i xDrive long term? |

Stage 3 setup here, no issues with front axles or joints yet. If you launch it hard on a daily basis though, you can expect due reduce the life span of certain components

About 18 months . Mechanical sympathy, Good fueling and short service intervals keep these cars happy

When you say short service? Do you mind elaborating on that or what recommendations you have?

When you say stage 3, do you mean upgraded turbo?

Also i do the transmission and other drivetrain fluids between 50-60k~ miles, so far i've done the transmission and transfer case, rear diff and front diff will be done soon as I'm just over 60k miles. ill be keeping this car for another few years at least so, ill look after it the best i can and do all the servicing myself so its pretty cost effective to keep the car well maintained
