The main issues for this car would be the engine and dsg 7spd mechatronic. As for speed sensor issue, its quite common and can be cheaply replaced at 3rd party workshops after warranty period (OEM's version is <RM100 excl workmanship iinm). Please also factor in the major service which falls on the 4th year / 60k km. I would strongly suggest the 2.0 tsi if you fancy a beetle.
