ECU Repair AM2900 main flash

As ECU specialists we code, programme and diagnose failed ECU’s. ECU Testing is a frequent task we perform however its not often we replace the main flash, in this case the am900 flash found in a bosch ME9 ECU. The Mercedes CLS 350 was having issues with the fans constantly running. Mercedes fans constantly running indicates an ECU fault in most cases. Upon inspection the AM2900 was physically damaged rather than re programme and hope for the best we replaced the chip and reflashed the origanal software, VIN data, MAPS and start authorisation.
