Anyone familiar with these codes?

Vehicle keeps throwing check engine light.

2009 335i 106k miles.

Well maintained, well rounded car have not had anything major happen with this car yet other than a water pump about 15-20k miles ago and blew the expansion tank coolant hose a couple thousand miles ago.

Codes:

P0108
P29F3 - fuel pressure sensor electric
P2EF4 - map-controlled thermostat mechanical

Any input would be much appreciated.

Thanks

P0108 Absolute pressure sensor, intake pipe, electrical:
Short circuit to B+
-Check wiring harness between intake-manifold
pressure sensor and DME
- Replace intake-manifold pressure sensor
- Replace DME

29F3 Fuel low-pressure sensor
-Perform electrical check on sensor wire and power-supply wires
-Visual inspection of plug-in contacts (on component and DME ends)
-Replace sensor

2EF4 Map thermostat
-Check heating of engine
-Check thermostat and replace as indicated

Are all these active errors?? If so I would check connections at DME since they all have that in common...
