The car is a 2017 M2 with Dinan intake, full FI exhaust (catless), and a piggyback Dinantronics unit. Ran great that way for about 10k miles now.

Over the course of the past week, I installed a CSF radiator, Wagner Evo II intercooler, CSF oil cooler, Turner Oil Catch Can, and did a complete fluid change (coolant; engine oil; differential oil) with intent to next flash with BM3 Stage 2 tune. However, before I could get to that last step, the car threw a check engine light, with display noting "Drivetrain: Cont. Driving Possible. Drive moderately. Maximum drivetrain output no available. Consult service center."

Using a BlueDriver unit, I also got a bunch of "Pending Codes" but these should not have contributed to the check engine light:

P0113 Intake Air Temperature Sensor 1 Circuit High Bank 1
P0111 Intake Air Temperature Sensor 1 Circuit Range/Performance Bank 1
P169F Throttle Valve Limp Home Mode Active (Bank 1)
P110D Throttle Position Sensor A and B Circuit Range/Performance (Bank 1)
P0123 Throttle/Pedal Position Sensor/Switch "A" Circuit High
P0222 Throttle/Pedal Position Sensor/Switch "B" Circuit Low
P0238 Turbocharger/Supercharger Boost Sensor "A" Circuit High
P2AB9 Wastegate Position Sensor 'A' Circuit High
P0193 Fuel Rail Pressure Sensor Circuit High Bank 1
P0108 Manifold Absolute Pressure/Barometric Pressure Sensor Circuit High
P0118 Engine Coolant Temperature Sensor 1 Circuit High
P0073 Ambient Air Temperature Sensor Circuit "A" High

I checked all hardware and sensor connections and saw no issues. I am wondering if perhaps the removal of the Dinantronics unit somehow resulted in an issue where I misplaced one of the OEM connections (driver side of the engine block) but doubt very much that was the case. I had not started the car yet, opting to seek some advice first.

Thanks in advance for any constructive input!

Cheers,

I am sure many folks had similar experiences post bolt-on installation...any input regarding those experiences and how you came to resolve any issues are appreciated. I had searched within this forum and did not see much on the subject matter hence created a separate post.

Thanks

Was the Dinantronics unit the true piggyback or the Sports unit?

All those sensors didn't obviously all go, all at once.. Its screaming a ground polarity short..

Check and see if any of the wiring is kinked or chafed..

Thanks for the input guys. The issue was the 2B connector to the DME. After applying some CRC QD Electronics Cleaner and reconnecting, all works normal 👍
