BMW 320d Touring (F31) in with a constantly rebooting head unit (HU-B). Common fault which we are able to rectify with a software update. As well resolving the reported issues, our customers often notice better running of their vehicles when the latest version of software is applied. Today’s vehicles are increasingly reliant on the software within them. Your BMW or MINI is likely to be using the same software as when it rolled off the production line. In the years since, BMW will have updated the software many times to correct or improve the behaviour of the vehicle. You can take advantage of the improved functionality by allowing us to upgrade your vehicle to the latest software versions. Here at Marc’s BMW, we offer diagnostic, coding and programming on BMW and MINI. We only use the best equipment and best methods. We treat your car as if it were our own and combine honest advice with correctly priced services.
