Moin together! I have recently been proud owner of a BMW E61. Since I have done all the maintenance and repairs myself on my previous cars, I would like to continue this on this vehicle. Unfortunately, more and more connected control units are installed in today’s cars and thus a simple maintenance is no longer possible without diagnostic / maintenance tool. My main requirements: – read out errors – reset maintenance intervals – if necessary coding / unlocking Funkt What do I need? What software (as cheap as possible) and what hardware (interface?) So I have a laptop (XP) with USB interfaces…
