Hello good people, I need some help! Turbo control solenoid. The wifes car suddenly has no power. Plugged in the lappie, and Diagbox tells me: "Turbo pressure electrovalve control", "Perminent fault", "Short circuite to earth or value too low". So I nipped out and grabbed a new soleoid valve, and whacked it in. Still exactly the same (my fault for thinking (only for a second) that this might be simple). I've now checked for vacuume, seems all good. Sadly I broke the vacuume reservior in the process (n0b!). Checked the voltage at the connector, reads 4.5v. Definatly some juice getting there then. Soo... wtf? What am I missing?
