"Swooshing" noise from fuel tank

[BigDean]

Afternoon all,

I am new to VW, and only 1 week in, so may seem like a daft question to some.....

When I am coming to stop or just manoeuvring slowly, I can hear a swooshing noise, which I think is coming from the fuel tank.

Is this normal? If so, I can learn to live with it, just want to check.

Thanks
Dean

Water in the bottom of the door? Give the door a wave..

I hope not, it is new, but if its not normal for the fuel tank, will try and locate more accurately. Thanks @Loz

We did have a thread a few years ago saying the same, most did not hear it.

Is it a T6.1? Mine was the same when I picked it up new from the garage. I mainly noticed it when the tank was filled over 75%. It was amplified by having no bulkhead between the load bay and cab, and no boarding etc. Since I've had the interior and sound deadening fitted its much better but I can still hear it.

Yes a T6.1. And full of fuel. It is very sound deadened but didn’t drive it before it was done so can’t compare.

I guess I will give it a bit of time.

Thanks

Plus I also had the hissing mentioned by @Peatey . I was told by VW that this was normal and to be fair it went away after a few weeks.

Sounds exactly the same as mine. I've had my 6.1 14 months so i think I filter it out now !!!

Me too. I’m coming to terms with it ... but I’m not happy about it

Actually, I think it is best described as “fuel slap”.

 

[VanDamMan]

This noise can be explained…Fuel tanks are designed with internal baffle plates this helps with the sudden shifting of weight and allows a better fuel level reading…but some tanks are unvented as the fuel moves the air is also moved and the resonance will transfer through the vehicle panels… it’s Normal ( I never hear it as the musics too loud and I’m death )

ps… on some vehicle if the pressure becomes to great the fuel cap will vent the trapped air

mine has something similar (t6, 68 plate)
Has always done it
I would describe it as more like fuel or adblue sloshing about in the tank when it stops
It’s annoying but you get used to it

I picked up a new T6.1 yesterday and noticed the sloshing noise on the way home- I was a little concerned so thought I would check the forum. Happier now I know it is not specific to my Van. I’ll just have to turn the music up a notch.

Have this on a T6 2018 - is there any areas to improve the sound deadening as I’m right at that point of build

I just learned to live with it.

I have bat senses and I hear it... 69 plate T6.

Same here, but only when tank is best part full, doesn’t do it when down to about 60%

It’s weird I have never heard a swooshing noise from the tank, but I do get a swooshing (surging sound) from the aircon, that goes if you turn off the AC.
