Internal radiator heater matrix - gallardo 2005

[Ropps]

Hi I have a crack in the internal radiator behind the dash , leak on passenger footwell (coolant)

Any technicians experts know what Audi part the matrix is.....

Ideally I don't want to purchase the whole system, as that is fine..

It looks exactly like an A6 heater matrix but I'm not sure as there seems to be so many variations
