Unfortunately, the only way to get the pollen filter replaced is to remove the ECU (Engine Control Unit), which also allowed me to have a good look at the plenum chamber. I found one or two interesting items in there
I also found a lot of dry debris and this is where I think I went above and beyond... I got the Vax out and actually vacuumed the plenum chamber. I must be mad
Go on then - tell me you all do that anyway
