Hello ..
actually am in trouble..
I try to do tuning on ECU .. M5 F90 brand new with 0 mileage .. I readout ECU by FLEX using bench mood .. sent the file to service files company .. they do stage 1 with POPS .. I write the file .. start the car and i get code for stage 1 malfunction.. they said its anti tuning issue.. after one day they sent another file to test .. wrote file and the car start very well .. i do test drive .. stage 1 good with great POPS .. but i see that catalytic begin too hot .. so I turned off engine.. then I waited for a while.. start engine again without any problem.. i moved the car to my shop to restore original file .. and that’s where my problem started..

restore original file .. and start engine.. RPM unstable!!! Do diagnostic i get more than 20 faults for EGS !! TCU doesn’t respond.. and the car can’t move

I open a ticket on magic motor sport.. they said that original file okay !!!
I try to do some research on internet.. I found someone that had same problem after tuned ECU ..

In pictures some of carzy codes that belong for TCU in ECU ...
Please i need help..

Ouch man sorry to hear your going thru that even with 0 miles on the car you didn't even get to enjoy it at all I have a 21 and I'm looking into options but this is one reason why I didn't want to mess with it . Hope you fix it ASAP and try to enjoy your new m5

I would get the car in the hands of someone that knows what they are doing before you do some irreversible damage.

You have a faulty transmission harness. Car throws a drive terrain error and it's stuck in park right? Some transmission harness are close to the exhaust and tend to short circuit. This is my experience .

You said your car is brand new and you have tuned it?
I have read that cars newer than june 2020 or so is impossible to tune for the time being because of locked Dme/Ecu.

Have you cleared the fault codes?

I would speak to Evolve and see if they can sort it for you. What year is the car? You say you bought it brand new, but it says 2019 in your bio?

Sounds like a partout....
