Mystery Coolant loss from Golf MK5 GT FSI

[sunshineGT]

Hi there,

First time on the forum :-)

I have a MK 5 Golf 2.0 FSI and have been experiencing mystery coolant loss. My normal mechanic (very relaible and honest) did a pressure check and found no obvious sign of a leak. Took it to a VW garage (Windrush in slough) and they said it was the thermostat housing leaking. Quoted me £380 to repair!!!!!

When I said this to my normal garage they said it couldn't be that and physically showed me --- they said 90% it could be the elbow and 10% the head gasket.

I have read up on the product k-seal and will see if this will help.

Any one else had this problem?

I have a 2008 GTI and have also been experiencing coolant loss.

Im guessing that it could be for the very same reason or does anyone else have any other possible explanations?
