If it's the same dealer you bought the car from then I would be calling in the dealer principle. Their staff are their responsibility and if they have sold you a tuned car without telling you (highly unlikely anyway) then they are surely going to be breaching some form of agreement, probably "sale of goods under false pretense" or along those lines.
You will be surprised how quickly these dodgy mofo's that plague VW dealerships across Australia will start playing ball when you mention ACCC, Australian consumer law and court proceedings. If suddenly they confirm that the car ISN'T tuned, demand a valid reason as to why they would say it is when it wasn't. If they start stumbling about an excuse, say to them -word for word- "if it was tuned, then surely the diagnostic system would have shown a TD1 flag, would it not?" And see what they come up with. Then, you should get some new clutches
Is anyone else getting tired of how many times legal issues have to come up regarding these bloody polo GTI's?!
