Spotted fluid leaking from under the drivers side floor...ie under the car not from inside out...its dripping onto the road...had a look and its comming from what appears to be two rubber tubes going the length of the car....its not oil...more like water.
Anyone any ideas....I'm asuming its just a perished tube...but what is it for.
Cheers for any help.

presuming you have a GTI with climate control

they are well known to discharge excess coolant once turned off could be this

Are you sure its water? There are three tubes that go under the car on the drivers side into the fuel tank. At least one of those is the fuel feed.

Just had another closer look...it is one of three pipes....defo watery type substance...not petrol...but one of the pipes goes to the rear brakes...so I'm guessing it could be brake fluid...I'll take her in tmrw to have it looked at.....is brake fluid oily?

there are 3 tubes....am I right in thinking its blue for petrol...black for brakes and clear for water for rear washer....just guessing on that one really.

fluid doesnt smell...is watery to touch.

I'm pretty sure for the rear washer the pipe goes through the headlining?

I had my car jacked up one day and noticed i had a leak coming from one of these pipes to. It was def water tho when i gave it a sniff. It was dripping from the small black sponge stuff.

Had a talk with a non VW mechanic...he had a look and pulled out the rubber plug that is where the pipes go into a bolted on section of undercarrage...basically a whole lot of water gushed forth...not continious..it stopped after a while....so he checks my levels and finds all of them spot on...his idea was that it could be 2 things.
1: the section of metal that covers the pipes could have gathered rainwater and basically become filled.
2: the pipe carrying what he thinks is the water to the rear washers being perrished...which in his words he wouldnt bother with as its a right bugger to get off and replace....its not pouring out its just a dribble so he said to watch my levels to make sure the water from the washer tank isnt going down and if it is make the decision whether to spend 100+ quid to get the pipe fixed...most of that in labour he said.
Hope that helps anyone with a simular prob.

Well there is some miss-information about the pipe, its def not the rear washer pipe, that goes through the inside of the car. Its probably water trapped inside the metal and running down the pipe but I would double check if I were you.

That's what I said.

cheers for all the help....I'll have to keep an eye out for your silver gti in Bedford Modified...I pop into Bedford now and again...I work in Rushden.

Cool, what colours yours then, I'll keep my eyes open
