Hi All, I've just been donated a (somewhat neglected) 2001 TD4. Engine sounds sweet enough. I've just serviced it (....once I'd sheared three of the bolts holding the undertray on)! It needs a lot of work, but so far I've done oil & filter, air filter and fuel filter. I've also done the thermostat (which I really didn't enjoy)! Among other things, I've noticed a small bore pipe (like a vacuum hose) that runs from what I think is the EGR valve actuator (a round, pressed steel capsule on the right hand end (as you look under the bonnet) of the engine) to nowhere. The other end of the pipe is just hanging down the front of the engine. Can anyone tell me where it's supposed to go, please?
