Re petrol vs diesel, personally, i would not go for a diesel due to the potential problems unless my usage (i.e very high miles, towing etc) dictated it. The mpg figures you mention for the petrol 1 series, seems poor. 1 or 2 forum members have, or have had cars with the 1.4TSI VAG engine, which seems to easily manage 50mpg. In addition, I took a 3.67 final VW rebuilt tranny, had the .71 fifth gear put on it, and transferred this with the 1.9L engine. This 1.9 NA has about 100 torque, a huge improvement over the original 1.6 liter NA. It took patience and time, about 8 months, to find this engine at a good price. While the TDI & TSI are welcome additions to the lineup, VW should avoid destined-to-fail versions like the Cross Polo. The GT TDI is India's most expensive B2 segment hatchback and is sold in 1 variant only. Due to its 1.6L engine size, the GT TDI attracts a whopping excise duty of 27% (the same as a VW Passat). The 1.2L Polos, on the other Is the 1.6 TDI engine from VW a good, reliable engine from 2014 onwards? - Quora. Something went wrong. Wait a moment and try again. Our verdict on the Audi A3 Cabriolet 1.6 TDI SE. The overall result of the A3's improvements is a resounding success. The new A3 Cabriolet is better to drive than the old one, with improved engines and suspension.

The 1.6 TDI should be the cheapest version to run, with road tax costs of £20 and a 68.9mpg The 1.6 CRDI D4FB engine was a 1.6-liter diesel engine that debuted in 2005. It was introduced along with a smaller 1.5 liter counterpart D4FA. Differences in the engines were achieved due to the diameter of the cylinders. 1.6 CRDI D4FB engines were intended exclusively for the European market. The 1.9 TD is a interesting motor. It shares the same bore 76.5mm and 95.5 stroke as the 1.9 TDI. I wonder if the old A3 1.9 TDI head would bold onto your IDI 1.9 block. If it does then one could install the TDI pistons and you'd have a TDI. Those IDI 1.9's are in 95' to 97' VW's and are usually quite expensive around here. Skodas also tend to perform well for real world economy; expect 45-50mpg for either the 1.9- or 2.0-litre diesels, 35-40mpg for the 1.8- and 2.0-litre petrols and an impressive 55mpg for the later b0U4.
