Help to identify part

I couldn't find part number.
Broke off one line, and now need to replace it.

Looks like air injection switchover valve. EPC shows part for your VIN however, online vendors claim not compatible check part # installed.

Brilliant service from konigstiger,

FYI mine stopped working.. it just needed some exercise. the solenoid I guess only switches at a certain point..... I just gave its an intermittent 12v feed and knocked it about, repeated about a 100 times and its been working happily for the last 3 years
its seems when working to give a bit more top end power

the bit it operates is the bigger designed in failure.... I would carefully clean and lubricate / then operate back and forth the silly vacuum operated inlet manifold variable inlet rubbish. the fragile plastic link rods break and you have a $700 parts and a 4 hr job to work around the deliberate need for a new inlet manifold
