VIC Engine Light on MKVI GTI

[eyelevel]

Hi all, im new to the forum and have had a Marck VI GTI since Jan 2010. After clocking up 63k rather quickly I am now lokking at trading. However, an orange engine light has come on. The book says its a Catlytic converter fault. However, the dealers intial look is a timing chanin issue. Engine is being pulled down as we speak.
In any case I am looking at Tiguan 155TSI as my new ride. Any thoughts?
