What the P1570 code means
P1570 is a manufacturer-specific code: the 1 in the second position means each automaker defines what it means, not the generic SAE standard. The most widespread definition is the one used by Volkswagen, Audi, Seat and Skoda. If your vehicle is another brand, confirm the code text with a scan tool that supports that manufacturer.
| Manufacturer | Meaning of P1570 |
|---|---|
| Volkswagen, Audi, Seat and Skoda | Engine control module locked by immobilizer |
The Volkswagen immobilizer lets the engine computer run only if it recognizes the key.
The computer sets the P1570 code when the immobilizer did not enable it: the engine starts and shuts off within a second or two.
Before you start repairs, confirm the make, model, year and engine. With manufacturer codes, the same number can change even between engines from the same brand.
