Hi everyone! This instruction will show you how to read and write 1.8 turbo Bosch ME7.5 VW Golf using MPPS V18 clone via OBD.
Something to know firstly:
Very Important!!! Before doing reading or writing, make sure your battery is charged up or use battery charger. Otherwise you will brick your ECU and the only way to recover it is to use BOOTMODE on the bench with additional power supply and different tool.
Don’t try to WRITE previously mapped ECU with this tool as Tuners might have Anti-Read/WRITE protection.
