'COD is Great' Do not make your decision until you have driven the 1.4 COD, it is a revelation! It is quieter and more refined than the diesel and is quicker to 60mph by 0.3 secs too. Yes, the diesel has more torque that is not disputed, 320nm vs 250nm but all of its extra 10bhp will be used to haul the extra 65kg in weight of the diesel engine. Coming from a 168bhp diesel Passat, I have no regrets about moving back to petrol and am getting more mpg than I did with the Passat. I have averaged 43 mpg overall on the 1,200 miles covered so far and have achieved up to 52mpg. These figures do not match the A3 diesel but the COD was £1,500 cheaper to buy and petrol is about 6p a litre cheaper and doing a small mileage and the superior refinement of the petrol engine I am happy I chose the COD having test driven both engines.
