I keep getting the Fault cade P003A:00-2E coming up at random times when driving. The car is a 2011 mk3 focus 2.0 diesel 163bhp. The fault says turbocharger/supercharger boost exceeds learned limit. Have had it looked at but they have been unable to find the cause. Any ideas welcome

Post your screen image with FORScan.
Post the Freeze Frame data if available.

2011 Ford Focus 2.0L - Fault code P003A:00-2E
One method to try is with FORScan is to reset the PCM after the fault has been cleared
If the function is built in, reset all learned values.
Road test and capture the faults.
The fault can also be attributed to a wiring connection that controls boost.
Vane position ? Is it stuck?

The best method to capture is when the fault is cleared.
Perform a road test and with the fault being recorded during that new test - stop and capture the screen.
The Freeze Frame offers the criteria or PCM state when the fault was captured in that moment.
