Went to start my car to leave work and out of no where I got the idle surge as if the throttle adaptations had been reset. Run codes and I get..

2ABC - DME: Boost-Pressure sensor, electric
2CF9 - DME: Throttle-valve potentiometer 1.
2CFA - DME: Throttle-valve potentiometer 2.
2d09 - DME: THROTTLE
2D1D - DME: Accelerator-pedal module, pedal-position sensor 1, voltage supply.
3100 - DME: Boost-pressure control, deactivation

I am not sure what would just cause this out of no where.

Things I have tried:
Clearing codes. They don't go away.
Unplugging battery for 15 minutes.
unplugging map sensor
unplugging TB connector
removing tb and cleaning and putting back on
checked fuses
jiggled some DME wires
reset throttle adaptions via MHD & pedal method

I can get the throttle codes to disappear, but they come right back soon as I try to start the car. The 2ABC and 3100 will not go away.

Anyone know what could be the issue? The only thing I can see these two having in common is they are both part of the same connector on the DME. I haven't tested but I was going to unplug/replug it and test.

I have a map from Motiv running FF. It has been fine for 2 weeks.

request for MOTIV to integrate the 3.5bar TMAP sensor support into the map and raise the "MAP Max Voltage" table to 4.65v. Make sure to "uncheck" the MHD 3.5bar support option when reflashing the update they send.

3.5 is integrated into the map. This has been running fine for 2 weeks.

Did you manage to fix this issue or you threw out the whole thing?

Turned out to be a bad Boost Box. Contacted Motiv and they sent me out a new one.
