How to Safely Read Mercedes CRD.11 ECU via Autotuner

 Question: Is it safe to read Mercedes W204 Delphi CRD.11 with Autotuner by OBD?


Autotuner or Flex to Read Mercedes Delphi CRD.11 ECU

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.
