Which Skoda is the best buy? I am about to dispose of a 57-reg Skoda Octavia 2.0 TDI DSG. The toothed belt is known to cause problems and my mileage is down to about 7,000 a year, so I am considering a new 1.4T or 1.8 petrol Octavia. I believe they have chain-driven camshafts. Do you have a preference for one or the other? Both are good engines. The 1.4TSI 122 is less powerful but more economical. Both have the benefit of a water-cooled turbo that acts as a heat exchanger and helps the engine (and the car) heat up quickly in winter. And yes, both have chain cams.
