How to remove P2DC7 with Softechpro V5

Recommended service: DTC OFF (generic). Step-by-step workflow:

  1. Look up the manufacturer-specific definition before deciding to suppress — generic P-codes can mean very different things on VAG vs PSA vs BMW.
  2. If the fault is benign or the underlying repair is done, Softechpro V5 DTC OFF suppresses the code.
  3. Load .bin, select DTC OFF, target the specific code, save patched .bin, flash back.
