Still trying to sort out my solenoid issue...
Singhg5 - I've got a 2011 B5, and the solenoid has 5 wires, permanently sealed of course. See my photo above - I've got the same paired small wires you have (one blue and one white), but I've got an additional small red wire diving into the glue as well. My solenoid is mounted aft of the battery, beneath the seat near the roll-over sensor, whereas it appears yours is mounted in front of the battery, beneath the fuel line.
The RE guys seem to be saying that the only solenoid they provide has the sealed wires, which is what I don't want. So, I'm back to trying to figure out how my solenoid is different from the wiring diagram and finding a functional replacement. I'm looking at tracing the wiring to sort myself out, but until it gets above 20℉ in my garage, it's just going to have to wait.
Has anyone else replaced one of these 5-wire solenoids with something that works?
