Questions before ordering
Which original file should I send?
Send the unmodified file obtained with your flash tool, together with the ECU or TCU identification and the read method. State whether it is a normal read, virtual read or slave container. Keep the original backup separately. File formats and backups →
Are these guaranteed results?
No. The figures are reference values for the listed engine. Software revision, installed hardware, fuel and vehicle condition affect the achievable result. The workshop remains responsible for diagnosis and the checks on the vehicle.
How do I request a revision?
Keep the original file, delivered version and logs in the same portal order. Describe the operating condition and observed behaviour so the revision can address a reproducible issue. Preparing logs →
Send the original. Discuss the file.
Include the vehicle, engine, software identification, flash tool and any hardware changes. The technical scope is agreed for the actual file, rather than inferred from a power figure alone.
