Reply With QuoteStill sounds like a bad contact. You could try to use a hot air station to find out if a part of the ecu is sensitive to temperature changes by leaving the car at idle with the ecu opened and slightly heating a part of the ecu.

Sounds like a checksum Problem. Only few software supports this special amg c30 ecu. It also has internel max value limit control. Most likely the tuning exceeds these values. Results of this are the same like checksum problem. Post full car error scan with DAS and post your tuning here.

I have tuned an C30 amg to 275hp maybe 2 months ago. I had the same problem - flash read ok with galletto and kess, but nor of them can upoad the modified file back to the ECU.
For me it was not a hardware problem. MPPS, Galletto and KESS were unable to do it the OBD way or bench direct connection. The only solution was to upload it in boot mode with MPPS. The C30 AMG EDC15C6 is a bit different than other Mercs. Only succesfull file upload is in boot mode with manually corrected checksum. I seriousy doubt it is a HW problem. Good luck.DPF/FAP, AdBlue SCR, EGR, Flaps, DTCs, Lambda, IMMO off, Custom REMAP

Read is ok both ways. Write is problematic when OBD. So write it in Generic -> EDC15Cx boot mode
It will work you will see.

use "no clean" flux from proven brands, few bucks more for a lot of saved time and headache
