Engineering write-up
After a turbo replacement, this Golf 7.5 threw a recurring P0234 (overboost) fault that no hardware adjustment could clear. We read the Bosch EDC17 file and rescaled the boost-control PID and requested-boost maps to match the new turbo's response curve, then removed the persistent fault code from the monitoring routine. The MIL cleared and stayed off across a 500km road test with no new DTCs. The customer also received a mild Stage 1 tune as part of the same file.
