Identification AW55-50SN, AW55-51SN (AF-23, AF-33) - Volvo, Renault, Fiat
Volvo, Renault, Fiat - brand new part including solenoid valves - intermediate plate 4D/3A -This valve body is the upgraded newest version. For some older models it is necessary to extend some wires of the harness to reach the solenoid valves. Alternatively a new wiring harness can be bought, but due to the expenses most mechanics prefer to solder extensions to the wires if needed. We suggest to ecxcute the relearn procedures after installation.
