After months of trying to figure this out I decided to ask for some help.

I have a 2014 BMW 428i
N26 blew and had it swapped with a N20 with 50k miles on it

Mods:
Injen CAI
Charge pipes on turbo and tb side
GFB diverter valve
Dinan Stage 1

I am receiving the following codes every other day or so randomly, sometimes cruising at freeway speed 70-75mph, this morning while sitting idle in park at work for 15min as soon as i had parked it i checked for any codes and had none, and then after sitting for 10-15 min the motor slightly hesistated at idle and i got all the errors

Motor electronics
101C08
107A50
100A04

Intigrated Chasis management
D02D58

Dynamic stability Control MK60 E5
D35A57
D36D56

All of them pop up simultaneously.

Any help would be amazing. I am pulling my hair out.

You have errors for the communication between potentiometer 1 and 2 for throttle valve.

Either you have voltage issues coming from the battery, a cable disconnection or malfunction to DME, or your throttle body valve is sticking and needs replacing.

Ok so over the last few months I changed to a brand new battery and had the same issue with codes off the bat, Codes still popped up every 2-4 days or so and send car into limp mode.

Replaced the Throttle body after that and to my surprise the issue was resolved... For about 3 weeks and now its back to throwing the codes every 2-4 days again.

When I replaced the TB i inspected wiring as much as possible and didn't see any issues with damaged wires.

I am almost to the point of giving up and paying a local shop $150 for diagnosis on this issue.
