Bubbling Water Sound

March 8, 2005

Please help. I have a D4 D

Everytime I rev the engine to move off from cold, I hear a watery bubbling noise coming from just behind the dash. It does not happen when idle @ 1000rpm. Front windsreen will mist up for a while, only on the one side though, (1/2 of it) and not the whole screen. The one-sided misty screen and the bubbling water sound will eventually stop when engine is fully warm and when I have the heat and blower on fully for about 20 miles?

Is it the Air Con system or is it the heater matrix? Are my footwells about to be under a foot of rusty water? Has anyone ever heard or experienced this? Warranty just ended. 2nd request for :help: Thanks.

I can't give you any help on this but I am looking for a solution to a similar problem. I have a 2.0 petrol Avensis and this has started happening having just reached 100k miles. I don't get any of the misting up that you are talking about but the gurgling is there when pulling away and is sometimes noticable when cornering smartly. Did you have any joy with yours?
