Gadgetoid Posted August 18, 2010 Report Posted August 18, 2010 (edited) I had this on a 02 plate Galaxy.It turned out it was the ELECTRICAL water pump - also known as the run on pump.These usually last to about 100k - mine was at 89k. It can give a clue that it is about to go by a harsh wirr AFTER you have turned off the ignition. If you can hear a soft whirr after switch off then it may be running normally.If it isn't working then there are localised areas of overheating within the engine block. The steam escapes by the expansion bottle, and it looks as if you have a slow leak There is a good how to on replacing this pump elsewhere on the site. Part was about £100 from VW. Or £150 from Frauds - guess which I bought? Replacement completely fixed the problem Edited August 18, 2010 by Gadgetoid
