[John110]

Hi All This is new to me a non Mechanic elder .I am puzzled by this problem.First on Road Dec 2003, model Citroen Jumper ( Relay UK) 2.8 HDI T605 Burstner model. Purchased in France February 2007 with 500kms on clock now2300kms.
Started to notice anti freeze lost small top ups needed. Had it pressure tested at main agents garage October and again in November 2009.
Put it into covered storage from mid November and collected to-day only to find almost empty anti freeze tank. Topped up did a long run for battery ( AA Start Flat battery ) No Significant loss now parked up at home need to talk to Agents Garage on Monday.Want to Sail Thursday!!!!
Any Ideas please

Antifreeze usually glows under uv light, try to get hold of a uv torch or light and check to see if you can see the trails.

Is there a secondary heat exchanger/heater in the habitation part of the vehicle, running off the engine coolant ? This or the associated pipework/hoses may be the source of the loss ?

Yeah theres a heater matrix buried in the dash any time I've seen a leak here its been very obvious on the cab floor. There must be some sign of a leak of that magnitude. If the vehicle had higher miles I'd immediately be thinking that it leaking through the head somewhere into the exhaust or intake or worse the crankcase. Have you checked the oil for contamination / emulsification.
