What years is Steptronic Auto Transmission available on the E39 540? I am looking for a 540 between 99-01. Was Steptronic an option or standard part?
Also, any feedback from anybody on the Automatic Software Download from Dinan? Its look like there the only one to supply transmission software where as there are a couple of suppliers for engine software.
