these cars are very prone to leaking heater matrix's I'm afraid

the best repair is to replace the part and on some VW cars ( of which SEAT is a part) there was an official recall to replace this part

so its well worth contacting your dealer to see if it appears on their recall list - however I can find no listing for it on the national database

to access the part you have to remove the entire dash needs to be taken out, then the heater box comes out (a/c will have to be drained etc) then the heater box is stripped down and the matrix replaced

also check the state of heater blower and the heater resistor as often these are damaged by leaking coolant
