Bentley GT Cont Mulliner 2005 Funny Air Hissing Noise
Discussion
Guys,
had my GT Continental for 3 Month,
runs great, apart from a Emissions light that stays on because of a faulty sensor.
its been turned off but comes back on again,
the fault is Lambor/Lamba Sensor. so not to worried about that.
gave the car a clean the other day, after that every now and then i can hear a Hissing Noise,
it sounds like its coming from the interior rather than engine.
so maybe once per journey at a random time i will Hear Pstttt. but more of a Breath in, like its sucking some air up rather than spitting it out. duration 0.5Sec, Quite Loud, nothing offensive, just a little Hiss, tried to figure it out don't know what vacuums are in operation and why in a Bentley, i know my Fords, but would not touch something like this so never bothered learning the ins and outs.
either coming from the dash or around the pass seat area.
im thinking i may have knocked something but it may not be related at all.
another unrelated question while, there is a
of rubber missing out of my tire wall, i have the rubber piece, the rim is OK, the wall took the full hit, its a big old car and i miss-judged a Curb.
anyone come across some compound to rebuild the wall (a flexicompound).
or reattach the old rubber
or a mixture of the 2?
Cheers
Nick.

...My guess would be a split in the Brake Vacuum Pipe work (and this can also bring on the Engine Warning Light) is the hissing noise you can hear.
Can you hear the Brake Booster Pump running in the passenger foot well? To confirm this, First check the fuse has not blown, then drive the car (with radio off ect) and see if you can hear a pump running in the Passenger Foot well. If you can, that confirms there is a vacuum leak and the pump is cutting in and out to build up the vacuum.
Hope the above helps?
