HELP!! Losing coolant.

[Simon TDI Sport]

I'm losing coolant, but can't find where from. Its an 06 2.0 pd tdi. I've checked all hoses the radiator, there aren't any pools of coolant under car or on undertray. HELP!!!!

check to see if the front carpets in the footwells are wet?

Bone dry! no wet interior.

Remove the oil filler cap and check for gunge on the cap. If its present then unfortunately it may be a problem with the head gasket.

How much coolant are you loosing?

Does your temperature gauge operate normally?

Does the fan cut in?

A leaking EGR cooler would be difficult to visually diagnose.

Also:

Pull the plastic cover off the top of the engine, there are a few small coolant pipes under it near the fuel pipes that run from the fuel filter to the tandem pump, I found one of those cheapo spring clips weeping coolant down the front of the block, a jubilee clip sorted it.

Already checked. NO problem there.

Losing enough to operate the low level sensor, every 2-3 days.

temp gauge works ok.

fan works ok.

Don't want to scar you, but the same thing happened on my Audi A3 2.0 TDI and that resulted in a new cyllinder head (out of warranty - £3000 ish). It's a very common fault on these engines (head becomes porous), so if you are still under warranty get it to a dealer fast and arm yourself with as much info as possible. My EGR cooler was the original diagnosis and that cured nothing. Do a search on 'Audi A3 coolant loss' or 'Golf coolant loss' and you will find lots of forums where people have had the same problems !
