I accept. collected my mk3 1.2 Tsi 110bhp manual hatch today,my Octavia mk2 vrs going in p/x. As my annual mileage has decreased to around 5000 miles per year it seemed sensible to go for a petrol this time.Very surprised by the power this little 1.2 unit churns out,Just wondered if there are any other mem
105PS from a 1.2, I make that about 85bhp/ litre which for a forced-induction engine is hardly shattering the world. The engine/ drivetrain is designed for a number of tollerences and has to be able to perform in all of the expected markets; so a 1.2TSI pulling a 1200kg trailer up a 1:8 hill in the Sahara needs to be kept cool and the drivetrain needs to be working within defined tollerences
The 1.2 R4 TSI/TFSI engine is 24.5 kg lighter the 1.4l TSI, has good power and torque for a small city car. The main target (replacing of old 1.6l engines) was achieved using modern fuel injection system combined with a turbocharged intake.
Nowhere is this more apparent than when the new 1.2 TSI 105PS petrol engine is combined with the optimised, two-clutch seven-speed DSG transmission. This delivers impressive power with excellent combined fuel consumption of just 53.3mpg. The four-cylinder 1.2 TSI engine is available in two power levels – 85PS and 105PS.
Was wondering whether these have timing belts or chain driven? Looked around on forums and owners manual but aside from the 1.6TDI I couldn't find anything on the 1.2 TSI engine. If anyone could confirm that would be great. Thanks! The 1.4-litre TSI engine is generally regarded as being a reliable unit, but with this particular example the service history is crucial. A high mileage such as this is not necessarily a bad thing if the car has been well maintained, and it is also likely that it will have included a lot of motorway miles which is usually undemanding for a car's mechanicals. The fix is a total overhaul of the engine, at a very high cost. If this wasn't enough, the motor has a huge appetite for oil, and 2006 models are known to sustain damage to the catalytic converter due to oil migrating downstream. VW 1.2 TSI petrol. The first 1.2 TSI engines are a real source of serious problems for the owners.

Safe choice is to swap the complete Engine + ECU from a Polo 1.2 TSi, retaining the current MT transmission. You should start hunting the engine from total loss car, restore with necessary internals. This is far reliable, less time consuming than turbocharging the current 1.2 NA mill and not to forget the cost will remain same for both the options.

Unhitched from a load this engine gives the Caddy a top speed of 125mph and a 0-62mph time of 9.2 seconds, illustrating its performance. Volkswagen added petrol-powered to the Caddy line-up in 2015 with buyers getting the option of the three-cylinder 1.0 TSI with 102PS, alongside the 84PS 1.2 and 125PS 1.4-litre engines.
