20,000 Inspection V70 / V70-BiFuel

Hello, the day before yesterday I was now on my first inspection. Now I have a few questions for you: – will the BI-FUEL-20,000 inspection not be tested on the gas system? On my note it was true: test gas filters and drain condensate and ground set, but the master said that this was not intended. They allegedly checked the pressure, but the tick was only applied on the note when I noticed the lack. – Another question: with me was garkein (motor) air filter (not the interior filter, which was changed) on the list and was therefore not exchanged. Isn’t that common with every inspection? How was that with you?? – is there the inspection regulations somewhere to look / download?? or can someone read me these? I have a V70-Bi-Fuel Bj 2006, model year 2007 Otherwise I was satisfied with the service of mine, everything in all 350 € (of which 100 € for oil alone…) Many dear greetings, “danfried”
