Doh ! It's pigging obvious when you look at the photos !!!! The big empty space and exposed white painted metal where the air filter should be should have been a giveaway!

Is it really the case that this van has no air filter, did the OP remove it to allow him to take pics, are we missing something?

From the OP first description " a pipe coming from the bulkhead in front of the passenger and hanging down in the engine bay."

Heater pipes. But he'd know if one of those was disconnected.

Hi guys, thanks for your interest. As Bartfarst said, the pictures show with the aircleaner removed. Now it's back with the necessary pipes connected, this mystery pipe, which doesn't show with the airfilter housing in place, remains situated  under the air filter and appears to rest on an earthing strap below the air filter. It appears to come through from the cab in front of the passenger seat. But I can't work out what it's function is inside the cab. Does anyone think a Haynes manual for a 2001 boxer 1.9td would be any help in solving the issue? If they ever produced such an item.

Many thanks

Hi
I've got a Brooklands Workshop Manual for 1.9 & 2.5 Relay and Boxer 1994-2001. I'll have a look in the morning, I'm off to hide from the thunderstorm !

Zimmy,
Is there any evidence that an intercooler has been fitted and removed ?

Would a intercooler have a pipe going through the front bulkhead. ??

Gently pour a litre of water on the windscreen and look where the scuttle drains from.

I've just been down to my Harmony and had look at floor level and there is a central heater vent under the dashboard, I can't see a pipe because it's encased but the type of pipe possibly indicates heat is involved somewhere.
It's the wrong shape and material for the scuttle evac. pipe as it's larger and smooth rubber.
That's my best suggestion now.

Does it actually go into / through the firewall or underneath it? the fuel tank is down there and that looks like a fuel related hose. Possibly a breather for the tank? My van is petrol so obviously has a different setup.

Thanks for all your comments guys, much appreciated. I know it's not the scuttle drain, but other than that ?????
