I just got my 2002 Beetle converted to grease. The other night I took my car out and drove 100 miles. The grease tank gauge did not budge, and my main gauge moved about as much as it would normally. So basically, I'm switching to grease, but the switch must not be working because I am not burning any grease. Is this a common problem for new installations? Could the mechanic screwed something up? They told me the solenoid switches appear to be working fine.
Yes, you need to go back to the installer and tell them what the problem is and have them test drive it and see for themselves.
Ask them why they think the valves are working fine and/or how they tested that they were working fine.
Do you have a temp gauge measuring the WVO temp? This is how I check whether or not I'm actually running on WVO. Since my temp gauge probe is after the supply valve is measures the temp of diesel (to low to register) when on diesel and the temp of WVO (noticeable change) when on WVO. I also have a vacuum gauge and notice changes in that when on WVO vs diesel.
