DPO, AL4

The original DPO solenoids are no longer available and have been superseded by the solenoids we stock. After fitting to the vehicle the ECU will need reprogramming by the dealer as they operate at a different frequency.

The change in production occurred in late 2003 or early 2004 depending on model or manufacturer (Renault, Peugeot or Citroen) and can be identified by a black electrical connector. The early ones cannot be purchased any more.
