THE mainstream Golf ‘6’ rollout is now almost complete with the delayed arrival of the 77TDI – the replacement for the old 1.9-litre TDI turbo-diesel.

But has the 77TDI been worth the wait? Is it as good as its popular predecessor? And would you choose one over the more expensive but highly impressive 103TDI Golf?
