Urgent - Advice needed

[Jetbags]

I was fitting a tracker today when i accidentally touched an aluminium corrugated pipe in the boot area of the car with a spanner that was touching the live battery terminal, a small spark resulted in a tiny puncture hole appearing in the metal pipe.
There was no fluid leak from the pipe, but i need to know what the pipe does before i dare start the car up, im worried it is something to do with the fuel supply.

The pipe is situated in the lowest part of the boot on the passenger side, located directly next to the live battery terminal, running vertically from beneath the floor and exiting what looks like to behind the rear passenger side seat. Does anybody know what this pipe does? it is approx 1.5inch in diameter, silver and corrugated/ribbed.
Any help gratefully received...

The car is a S Class 500e Lwb Hybrid plug in (2016)

Hi,
have no idea, but if no liquid came out and if there was no new smell from it it may well be part of the ventilation system or vent off for something. It seems like it was pretty thin material. I don’t think that it it a fuel supply at an inch an a half.
hoping that someone will have a better answer..

You could go on Ebay and search for "W222 pipe" and see if you can see anyone selling a pipe that looks like the one concerned. The item's description should hopefully tell you what it is!

again, without pics it's hard to say, but sounds like it could be a noise generator (fake exhaust noise), they are sometimes fitted in the boot and have fat aluminium pipes.

Yes, everything still working fine, bizzare set up, have watched fifty youtube videos and googled myself to death but cannot find another S500e with the same pipe in place. I look like a right wally laying in the boot sniffing an alluminium pipe ! surely Benz would not put a fuel pipe so close to a battery??? if not fuel then what else could it be.... a breather pipe for ??? a conduit for electrical wiring ???? nobody seems to know.

I don't have such a pipe although mine is an W222 S500L.

I wonder if your extra pipe is aftermarket.

I don't think it is the battery breather pipe as that is around 5mm diameter on mine and rubber, and you can trace that to the left side of the battery in the boot where the spare wheel would once have gone.

The fuelling would not run near the battery because of safety.

If you are in Kent and near Tonbridge, AMF are there and know their stuff.

As above take it Alex at AMF rather than main dealer if you are nearby.

Ok, so here is a picture of the pipe being discussed... does anyone have any ideas what this pipe does ? You can just make out the tiny hole created, i have just applied some steel paste over the hole to contain it....

What about MB parts dept buddy , in case it’s genuine fitment ?

 

[zipdip]

So the op has produced a picture and nobody knows what it is,could this be a first,just dob't ask me have not a clue,weirdly the drain off from the battery goes into the black plastic housing and so does the silver pipe

To me, this looks more like a shielding tube, protecting what's running inside, rather than actual pipe or hose.
