Bulletin Summary
BMW offers a new special ISTA Installation made available for Roadside Assistance / Mobile Service technicians. The new ISTA Version is also able to be used in case of a Remote Software Upgrade (RSU) programming failure to get the customer car reprogrammed on site. In case of a Remote Software Upgrade failure, the engine start is prevented for safety reasons until the vehicle is programmed correctly. Most of the errors occur when only one control unit fails to program correctly.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
