VCDS Measuring Values Blocks 140 and 143.
Minimum coolant temp = 50C

Not in regen... If you see one of the fields in MVB 143 = 18.4 while the others are some smaller value, under some load, then that's a bad pressure sensor and or injector. All of them = 18.4, then it means the diffference is enough to put you in "mini limp mode" so to speak.

If you see MVB 140 with one of the 4 fields that remains significantly different from the others = bad injector

Peak cylinder pressures are not all that relevant
