2015 Mercedes- C220D Delphi CRD3PLUS.A0 TC1797 ECU reading and writing review:
Flex could not read/connect via Bench or even OBD- Tried both pinots, Tried TC1793 etc.
Pulled out Foxflash with the same result.
In the end completed with Autotuner worked first time.
Very Strange as have done many of these before and there’s no info out there to say this can be a case.
But looking through the forum a couple people had the exact same issue.
Conclusion — there’s a small batch of these which can’t be done with flex etc.
So if you have this issue try with Autotuner!

Question: Is it safe to read Mercedes W204 Delphi CRD.11 with Autotuner by OBD?
Here is the clue.
Yes, it is safe. Only OBD on Autotuner. Turn on a charger with at least 60A, because the cooling fan is working at max.
Use voltage regulator. Read and write takes 10–15mins each so connect charger.
But some people crash this ecu with autotuner obd. Most time when ecu has modified file before. But the customer don’t know.
Same as Foxflash, better don’t use AT for Delphi CRD ECUs, use Flex.
Flex is better. Flex works fine, with bench protocol.
Best way is bdm if you do not have flex with old ktag.
