Default Lead in glovebox = Broken down N54 - 09-23-2020, 11:53 PM

Hi All, Just bought an E93 N54 that came with a JB4. I was sat in traffic, and found a lead with a USB plug sticking out from the removable cover in the glove box. I pulled it and the car went into meltdown. Felt like it was not getting any fuel and the revs were extremely erratic. It now starts but the revs falter and the engine stops after about 5 seconds. My best guess is that it relates to the JB4 and I've disconnected something. Ran the codes below but they don't mean much to me as I'm a total noob. Any help please?!? Cheers!

29E2* Fuel injector rail, pressure-sensor signal*
2ABC* Boost-pressure sensor, electric*
2D20* Accelerator-pedal module, pedal-position sensor,*plausibility between signal 1 and signal 2*
2D33* Absolute-pressure sensor, intake manifold: signal*
2DIC* Accelerator pedal module, pedal-position sensor,*signa12*
2F71* Electronics-box fan, activation*
2FBF* Fuel pressure on release of injection*
30FF* Turbocharger, charge-air pressure too low*
3100* Boost-pressure control, deactivation

you'll have to open the dme box to see what came undone. hopefully nothing broken and just needs re-connected.

Thanks - shall have a look this afternoon. I think I'll take it out and reinstall. See if it works stock first. Possibly oxygen sensors also?
