is this tube supposed to be here?

[roboldham]

Was driving into the office - fair clip - got a BZZZZZZZ noise briefly, sounded like it was from the front left of the car - like something rubbing against a fan or a wheel arch.

Disappeared after about 5 seconds.

Checked underneath motor and saw these (pics) - supposed to be there?

Isn't it a breather pipe?

It's the radiator drain hose. It's so you can drain the rad without filling up your undertray :)

Buzz could have been a bit of debris off the road. Only worry if it carries on doing it...

Can't say I've ever noticed a pipe there, but then again I've never looked.

I think the buzz was the charcoal canister purging.

I think the charcoal cannister is located at the back right of the engine bay and can gurgle/ buzz. Its some sort of filtration thingy, there are a few old threads on there purpose and cleaning them etc, don't think you'd hear it from inside the car though...

Rob, I think I've spotted that on my car too.. thought for a minute a hose had come loose :)

LOL - I got some of my staff and people from the office next door all out peering under my car and in the engine bay in the freezing cold!

I think I had better 'fes up to them and say I over-reacted :-)

Still cant figure the BUZZZ noise - think I may have got some debris in the hub / caliper or something - I was doing about 165 leptons at the time. Scary.

John:flame Dev i would say same follow pipe back to source. think the rad drain pipe is white next to the drain tap.

when i had a leak and found out it was the waterpump i had a pipe hanging down in middle of engine i thought it had come off turbo or something. turns out it is the waterpump overflow pipe.

that pipe in pic is nothing to worry about

Sorry. I skim read the first post and though the noise was heard when the car was stationary. :stupid:

:p

Radiator drain hose, thankyewverrymuch. Besides, I've been under the car, wondered what it was, and traced it back all of four inches to... the radiator.

i would still go with the battery tray drain pipe. in the pic it looks too far set back to be radiator drain plug. when i fitted intercooler hard pipes there is 2 pipes that i remember.

anyway they are not inportant like he was thinking something had come off

have fun

Does it matter???

Its a drain hose, no need to panic about that bit.

[Supra_Al]

It may be the air-con drain pipe,as this is a by product of A/C,water. Al.
