I bought my gti on saturday and has been running fine until today, was driving home from uni and on the way the temperature started to rise slowly, then quickly overheated and temp light came on. i pulled over and turned it off and cooled it down a bit then checked oil (not much oil but hard to accurately tell as car was on just before), coolant level is fine but car is definitely over heating after 5-10 mins of it being off i opened bonnet and could feel the heat on my face as i opened the bonnet. turned it on again and the temp level was one bar above 90 degrees and i drove it home very slowly not taking it above 1500 rpm and it stayed at that temp until i got home and would go up if i revved it higher.
Could someone please tell me what could be wrong, if there is a mechanic who can come to my house and check it or someone with vagcom in sydney close to canterbury area ???
