All models fulfil EURO 4 emissions criteria and the 1.9-litre TDI, for example, has a VED Band A rating giving good Benefit in Kind tax breaks for company car drivers. Insurance group ratings range from 4E for the 1.4-litre petrol S up to 13E for the 2.0-litre GT FSI petrol. * Performance, Reliability, and Longevity: Today's diesel engines are highlighted by torque output of 910, 1,000, and 1,050 lb-ft that gives trucks ability to tow more than 35,000 pounds and carry True, there are a few mechanical problems to look out for and there are other engines like it that can do an equally good job, but to answer the main question – is the 1.9 TDI a good engine – the answer is yes. For those seeking something that’s great for cost-efficient, dependable driving, this is one of the best for such a task. If the turbo fails it's about $1200 new. Add the dpf to that too since the turbo typically pukes oil into the dpf which clogs it with oil. The serpentine belt can also fail if diesel fuel leaks on it. The failure can lead to lots of bits of the belt getting into the timing belt area of the engine. A new 1.6-litre dCi diesel was introduced in 2012 to replace the 2.0-litre unit and it's both more powerful and more economical than the 1.5, though the smaller engine is cheaper to buy. 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. They are definetely diesel pistons, and they are .05 mm oversize, making the bore 77 mm. They look exactly like normal 1.6 pistons, and have the same style crown, and they also weigh about the same as normal 1.6 pistons. Thing is, with a 1.6 crank and rods, these pistons do not protrude above the block at all - they come about 5.5 mm short. There is a choice of two petrol engines and two diesels; a 1.0 litre or 1.4 litre TFSI four-cylinder petrol engine, or a 1.6 or 2.0 litre TDI four-cylinder diesel. With the shockwaves of Dieselgate still rippling out across the car market, and few owners likely to drive their Q2 to the moon and back, the 1.4 TFSI seems like the most sensible xqLXBVk.
