Hi all, a couple of weeks ago I noticed a slight slooshing noise (you know, water swilling about) coming from somewhere in front of the driver. Since first noticing it the frequency and volume of the noise has increased as if there's more water there now than before. I get the noise mostly when cornering and during braking but also sometimes during rapid acceleration.
I've had a couple of looks to see if I can find where it's coming from but everywhere's bone dry! It struck me this morning that maybe it's coming from the heater matrix. Does this sound likely - I thought it would be full and, therefore, silent. My reasoning for this is that when I had the biofuel conversion kit removed they had to disconnect the heater pipes to remove the heat exchanger. Could an air-lock have formed and still be in there? The heater has hardly been used since.
Thoughts?
