v220 ambiente heating ystem I have been trying the various options to cure my heating system however I have found a grey capillary air line under the dash I cannot find where it fits when I first purchased the vehicle the turbo didn't work and the garage found it was sucking air from a grey pipe that went under the dash they didn't want to take out the dash to find out why so they blanked the pipe under the bonnet until I could find out where the pipe went to, when I changed the cabin filter I found the grey pipe close to the steering wheel but cannot find where it fits also found a green pipe with a L shaped rubber connector that isn't connected to anything both the green and the grey pipes are just above steering column can anybody tell me where they fit
