I still smelled with a closed tank cap when you open it is a few meals, almost always above or under pressure in the tank. Man hears after motor shutdown after a long drive the tank covers a bit flood, in the tank lid is a not ventiel, so whom de tank airing or de-airing does not work dan goes with a certain under or overpressure that ventiel in the tank lid a bit open and that I hear also happen. I guess it's a lot of uberdruk in the tank because you smoke the bezinft smoke at the lid (is lid really German?).
Already done: tank lid and backslag valve and wires and cleverly controlled.
The masters who have to inspect the car for the APK (with you HU?) does not like this.
Have you had this problem and polluting the stock coal tank met his tank airing tested, I mean if the airing is perhaps dense and dirty.
Can you check the ACB without removing the wheel shell and if you want to dismantle the ACB then the calipers need to be removed or can you remove the ACB through the only wheel shell?
So again many ask, apologize again my German language and I am grateful for every contribution.
Many greetings from a warm Holland
