Ensure you have a well charged battery and furthermore one that is in good condition. We ask that if you have any outstanding concerns with the charging system of your car that you rectify these concerns before proceeding any further with any flashing procedure. Connecting your car to a battery charger is highly recommended especially during the first flash (flashing time 4 – 6 minutes). After the initial setup any next OTS Stage Flashing will take up 15 -20 seconds and will not require charger however still highly recommended. The charger should be connected to the designated charging points in the engine bay which can be found in your BMW User Manual. MG Flasher is intuitive in the sense that it knows when the car battery is low and once it detects a low battery condition it will abort/prevent a start of the flash procedure. It is very important to keep the car battery within optimal voltage during flashing; we are not responsible for any damage to the ECU during flashing if above requirements are not met.
Make sure to turn off the radio, headlights, interior lights, AC/heating, heated seats as these are all electrical components that draw power from the battery. This is extremely important for the first long flash. If you have installed any aftermarket components make sure to turn them off or disconnect them, this includes any piggyback hardware such as a JB4, which cannot be run in tandem with our software anyways.
