Can anyone help I'm getting a strange hissing noise from inside the dash (top center) every time I add power. The noise goes away when the power is off or when I'm coasting along. Some times this noise is joined by a short girgle (like bubbling liquid).

I cant find any air leaks under the hood, so thought it may be in the AC. any idears any one!!!

 

Thanks Chris

Could be the aiv's ( a long shot i know but worth checking) as they make some weird noises when they get water in the U bend on the pipes.

Apart from that you may have a boost leak but you should notice a drop off in power if you have.

 

If it was the heater matrix, you would have wet feet so i dont reckon thats the prob.

 

Good luck.

No chance of that, it's an NA.

 

If you are in my area give me a call, we'll take a look at it.

thanks Stu I may have to have a drive over so you can have a look. Hope its not the heater altho it never seems to get verry hot

in the cold weather..

May be I could come over one night this week

We could make it an excuse for a beer (if your off the pills)

I'm no mech, but I had a car with a fault in the heater matrix that made those sorts of noises.

 

Does the Z have something similar?
