coolant leak on vw polo 1.9 tdi

[vw754]

Hi all.....2002 9N polo 1.9 tdi sport polo,took undertray off and cant find any coolant in that or anywher apart from ....under the chassis...drivers side the chassis is dripping with coolant after a drive ,cars all nice and dry inside.
Its got to be from engine side but i cant find it around that area at all,even the undertray is dry.........any ideas?
Maybe its leaking when i drive only? new water pump and cambelt replace a year ago but only done around 5,000 miles since they were fitted (genuine parts) no other issues with the car whatsoever cars done 61,000 miles with vw dealer history.
im worried could it still be the waterpump?

Do vw service it? I asked for them to check to find it. Of vw done cam belt it should have a warrenty to if it is the water pump they should fix it under a warrenty. They don't tell you that bit tho

unfortunatley...i got the job done privatley a year ago,using genuine vw parts. i may have mis-quoted the belt and w/pump change,its actually done around 3,000 miles and not 5.

hi,found out the heater matrix is leaking,luckily its leaking outside rather than in the car.......its leaking where the to pipes go into the matrix at the back of the engine,how does the matrix come out is it a full dashboard removal ?
