Getting a very intermittent P0234 Code on my 2017 L405 TD6...it seems to go on every couple months and then clears pretty much right away (after 3 start/stop cycles). I'm reading BP_A_CMD = Boost Pressure Commanded and BP_A_ACT as Boost Pressure Actual? It seems like it is showing an underboost from my limited knowledge. These boost numbers have always been very close < 1 PSI when I observe with live data. I believe the code needs a > 5 PSI difference for a certain number of seconds to trigger. Thought it could maybe be related to the DPF but not sure.
