P1570 — VW/Audi Immobilizer Active — engine start blocked
VW/Audi diagnostic code. Below: what it means, common causes, symptoms, and the exact bench-programming fix path.
Common causes
- •Cluster EEPROM (24C64) damaged from a failed key attempt
- •Cluster ↔ ECU pairing data lost
- •Used ECU installed without IMMO adaptation
- •Aftermarket key without proper coding
Symptoms you'll see
- •Engine cranks normally
- •Engine starts for ~1 second, then dies
- •"IMMO" warning on cluster (or cluster dark if 24C64 damaged)
- •No fuel pulse on second crank attempt
The fix path
VW & Audi MED17/ME17 IMMO Delete ($250). Permanently removes the immobilizer dependency at the ECU level. Works even when the cluster (24C64 EEPROM) is damaged — common from previous locksmith attempts on 2011-2016 VW Jetta.
