Fault codes 2D18 or 2D25, "Manipulation protection, max air mass", may be stored in the DME, indicating an implausible airflow. To prevent possible engine mechanical damage due to increased turbocharging pressure, the DME will limit the maximum available torque to the nominal torque value of 400Nm

i got these codes with a jb+ and its not clearing them before service thats the problem, its the limited power, does the jb3 get these 2 codes as well? i'd think it would get it more because higher boost levels but i could easily be wrong.

The JB3/JB4 use fuel pressure control to avoid them. The JB4 itself can read/delete hidden codes so you don't even need a BT with it!

thanks mike. it was just a thought i had for people running more boost. i didnt know if it became more of a problem. thanks for clarifying.
