Loosing water on a regular basis no leak on ground ??

[carmine]

I own 59 plate VW golf Mk6 1.6 bluemotion and once or twice every week or two warning light comes up and I have to too up water bottle. Like I said no sign of water on ground. Anyone else had this problem ?? Please advise ??

my money would be on the EGR cooler leaking internally

No, I bailed out of diesels for good earlier this year when I sold my 13 year old passat, just acquaintance with a troublesome 1.6 and discussion on this and other forums. These EGR coolers seem to get replaced reasonably frequently when the EGR valve fails, which is integral to the cooler. I've seen figures of several hundred £ for replacement as its a time consuming job and recommended to fit OEM equipment rather than aftermarket. An internal coolant leak in the EGR cooler would not be visible and the coolant would be evaporated in the exhaust gases. It could be a minor external leak from hose or waterpump etc that is not usually visible as it evaporates before leaving a puddle, but you might see a pink antifreeze crust building up at the leak point or it could be a head gasket leak, which would be another internal invisible leak.
