Have just sold my 2019 BMW 540i after converting it back to stock. Have a pristine Dinan software package complete with instructions ( this is a easy installation) for BMW's with the B58 engine. Kit is only a year old. Makes a big difference !!!!. Dinan shows this application works for many models such as:

DINANTRONICS X - 2016-2021 BMW M240i/340i/440i/540i/640i/740i/X3 M40i/X4 M40i



Paid over $600…..yours for $350 via paypal shipped anywhere in the lower 48 USA. You can email me at gcono1@roadrunner.com for pics etc.

thanks ,

Gary
