I successfully cleaned my Regina CIS a couple weeks ago. In my case I was getting a trouble code, and an occasional hard/stumbling start. First, I removed the unit from the car, and ran carb cleaner into both ends, shook, and drained. Then I hooked up 12 volts to the terminals and ran the plunger back and forth a few times, more carb cleaner, more 12 volts, etc. until the carb cleaner came out clean. Reinstalled and now works great. No trouble codes and no hard/stumbling starts.

The regina cis is different than the bosch in that the bosch is a motor that opens/closes a valve whereas the regina is a solenoid-operated plunger thingy.
