I drove my e53 to 205k mi. Never serviced TC or trans. Was going to change fluid in the trans but instead I changed the whole car to e70.

People that use Windows will often get the software suite for working on BMW. The software I think is technically pirated but easy enough to obtain. F to A ratings from people getting it running so your mileage may vary.

I hate windows and 30 yr old software that is largely German so I instead bought foxwell NT-510 and it's always done what I needed. The key is it both can access the BMW modules and is bi-directional.
