So, I was able to pick up my thickness from the LPG conversion. The system: Vialle, 83 liters wheel pit tank (compressor chassis was categorized in the trunk), tank pits under tank lid tank indicator in the footroom, only to be seen by the driver. Driving: don’t notice any difference…. The consumption: too early to say… The conversion company: www.gag-autogas.de in Lünen near Dortmund, have a lot of experience with Phaetons, are friendly and competent, everything done as agreed, clean work. Now I just hope that it remains that way, you really don’t notice anything, you could even think it runs on gas a little better, quieter, but could also be imaginable. I will report again after 2,000 km. Greeting Flodder
