just bought mk5 gti laser blue i believe suspected head gasket

[GJSEB79]

as above guys just bought my first mk5 golf gti dsg in laser blue just got home and checked it all over again an there seems to be a goo on fill cap and the little chamber part below is this head gasket or is this going to be condensation as the people say they have only done like 3 mile short journeys in it has only done 50k surely cant be head gasket

What colour is the coolant? A nice pink (or blue!) Or a dirty colour? If it looks clean I'd assume condensation as the previous owner says they only did short trips...... Give it a motorway blast and when its cooled down re- check for the 'Mayo'.

a up mate coolant is a nice pink colour checked that mate the mayo looking stuff is like a yellow stroke green colour

[andyr]

How about the dipstick, any goo on that?
When was the last oil/filter change? If it was a good while ago then perhaps a good idea to get it done.
I'd still assume condensation first tho.
Give it a good run 
Did you buy it privately or a dealer?

I have also noticed like a loud ticking noise like there are tappet noise but louder when warm

Could that be something to do with a faulty gnition coil pack?? Or carbon canister??

I had the same when I bought mine bud, took it on a decent drive down the motorway (like 30/40mins at 70mph) and it all cleared up.

And with regards to the tapping, these direct injection engines are super tappy to begin with, if you are genuinely worried pop down to your nearest vw garage, they won't charge just to listen to your engine

TFSI Head Gaskets are not known as a weak point - I would also suggest that this is just condensation. Mine suffers from this in cold weather.

Most likely the injectors:
