Hello As a new Lupo driver I have an (old-known) question At the beginning an apology. Even if some already “hangs out” the topic and one would like to refer me to the search, I have already done this, but as a technique layer did not find the right one and ask for your help I bought today a Lupo 1.0 Bj.11/99 with engine AVN. By researching the Internet I met today the topic of the “frost death” at 1.0. Since my car is not available I had to check the hose from the air filter down to the plastic box (oil separator?) with my hand. There is nothing in or on the hose that looks like heating. Question: Should the heater (cable) be in the hose and thus feel-able, or is it installed in the oil separator? Unfortunately, the seller (3rd hand) could not tell me about the status of the tube. Thank you very much for your answers. Greetings Eisenbiegeropa
