P1570 — Engine Start Blocked by Immobilizer

BMW diagnostic code. Below: what it means, common causes, symptoms, and the exact bench-programming fix path.

Common causes

  • •Failed EWS module (E36/E39/E46/E53 chassis)
  • •Failed CAS module (2006-2012 chassis)
  • •Damaged key transponder
  • •EWS-DME pairing data corrupted
  • •Aftermarket alarm interfering with immobilizer wiring

Symptoms you'll see

  • •Engine cranks normally but won't start
  • •Engine starts for 1-2 seconds then dies
  • •EWS warning light on dashboard
  • •Other paired keys also fail

The fix path

Diagnose whether DME, EWS/CAS module, or key transponder is the failure. For EWS-era cars (E36/E39/E46/E53), BMW DME EWS Delete is usually the cheapest correct fix. For CAS-era (2006-2012), BMW CAS Key Programming or used-CAS virginize. For 2013+ F-chassis, BMW FEM/BDC Key Programming.
