I’ve checked with Eng Sin regarding this concern.
Part number change is required for our Bosch internal tracking purpose when we have software change. Re-flashing at Thailand is not available due to we are not allowed to reflash the software out from Bosch except Anderson. This is the direction defined by QMM.
Therefore only possible to perform the software update at PGP1. Reason is that other location except Anderson and Bosch production plant doesn’t have the proper software reflashing setup and testing to ensure the correct software loaded without quality problem.
Please check with Moorthy for any further concern. Thanks
