1999 2.0l HDi 110 estate.

Just plugging everything back together after a coupla days on me back in the snow doing a cambelt change and I leaned on this wee fella and it snapped off
What's it do?
What's it called?
Looks like something to do with air intake as that hose it comes off is about 2" diameter so prob not coolant.
That large hose comes off the top of the small rad (heat exchanger ?) on the nearside of the engine bay, just in front of the airbox and battery box. The pic is taken from the front nearside wheel looking accross (and slightly forward of) the engine bay
Thanks in advance.

If its off the air intake, could be air to idle control valve hose?

Altho that looks like intercooler?

Yeah, intercooler.
You can repair that by buying a straight plastic jointing pipe from a factors/accessory shop and drilling it out to give a snug fit then glue it in with epoxy.

thanks fellas.
Is that some kind of sensor it's connected to?
Will the car run without it until I fix it?
I had to put the battery on charge tonight as it's too flat to turn the engine over, so should get it fired up tomorrow again, IF I've done everything right.

cheers

Will a piece of 10mm copper pipe not push in the hose, then into the hole on intercooler? Hold it in with cable ties?

You will be able to run it but you won't have turbo boost as you have a hole in your intercooler.

Whatever is used to repair it, it must be air tight to give you boost.

It feeds #16 down the bottom here:

Pressure sensor air entry

So it'll depend if it likes running without this (be interesting to know what sort of errors this gives)

A suggestion

OK thanks everyone, yet again this forum's members come to the rescue of an ignorant owner
O know what it does now and what to look for to fix it, and have also realised that the CD manual I bought on ebay last week is as much use as a politician's promise. I'll get a Haynes asap.

I reckon we should post something about the useless CD manual on evilbay somewhere prominent, you're not the first to be caught out by it

FWIW that's the MAP sensor - measures the turbo boost.
While I agree with the others that you'll lose boost because of the leak, there's also a danger of over-boosting as the ecu won't see the pressure. If you have electronic boost control, (HDi 110 or 136), I'd take it real steady till you get it fixed.

Yes it's the boost pressure sensor, it should just go into limp mode (when my I/C hose blew all the boost was pissing out and it went into limp so I'd assume yours would have the same effect as the sensor can't 'see' the boost).

I think you fail to appreciate this needs to be a lot better than airtight at atmospheric pressure...

BUT... What about a bit of copper pipe the right size to fit inside the MAP sensor hose, flared at the end and pushed out (and glued in) from inside the intercooler connector, so inside the intercooler plastic you have glue as a seal between the plastic and the flare, with the boost pressure pushing the seal tighter...

Why sod about? Something like that one in my link will be perfect (providing the pipe isn't too much bigger) and costs pennies (probably less than a bit of copper pipe)

Thanks again fellas for taking the time and trouble to help me out here with your advice,, all very much appreciated.
I'm gonna get it started today, when I wrap myself up in enough layers of thermal clothing to go outside.
Then put the last remaining parts back on, wheel, arch cover etc. Then leave it on the driveway until I either get something like Steve suggested or scource a 2nd hand replacement from a breakers.

pffft! A clever hack ALWAYS trumps better methods, especially if it involves 5x the cost and effort
