Hi Perry,

I can see why the confusion, as there were examples of the 2009 Audi A3 2.0 TFSI engine that used timing chains and others with a timing belt. If it has the latter, then the interval is 180,000km regardless of time. The engine code starts with BWA. If it starts with a 'C' then it has a timing chain. Also, just to confuse things further, the BWA engine has a small chain joining the camshafts at the back of the engine as well as the timing belt at the front.
