The Touran was the first vehicle to use Volkswagen's 2.0 TDI engine. The engines available at the launch included a 1.6 FSI and two diesel engines, the 1.9 TDI with 74 kW (101 PS; 99 hp) and the 2.0 TDI 103 kW (140 PS; 138 hp). The engines are EURO 4 compliant, except the 1.9 TDi when paired with the DSG (direct shift gearbox).
So what really is the difference between the TSI vs TFSI? The short answer is, not a lot, but there are some minor differences. For starters, TSI stands for “Turbo Stratified Injection” and “FSI” stands for “Fuel Stratified Injection”. These apply to both Volkswagen and Audi direct fuel injection engines. Believe it or not, TFSI stands for “Turbo Fuel Stratified Injection.” This technology is not only featured in the but you can also find TSI and TFSI in In this guide, we’ll be focusing on the engines. The main engine bases these engines are built off of are the EA113’s and EA888’s. In this guide, we’ll be going over the mechanical and technological differences between the TSI vs TFSI. FSI Engines The FSI engine was first introduced in Volkswagen’s 2006 and older. The vehicles you could find the FSI engines in are MKV Jetta’s (A5), GLIs, GTIs, Tiguans, Passats, and CCs. The engine base for these engines is mainly EA113 and it puts down 200hp and 206 lb-ft. In the weaker EA113 engines it features a BorgWarner K03 turbocharger, and in the more powerful engines, it featured a KKK K04 turbo. EA113 common engine problems are: High motor oil consumption Engine knocking Difficulty accelerating at higher RPMs Loss of engine performance (Mainly due to the N249 Valve or the PCV valve) Carbon buildup in intake valves TSI Engines The TSI engine superseded the turbo FSI with important technological and mechanical updates to address the downfalls of the FSI. It was first introduced in Volkswagen’s and Audi’s in and is still found in vehicles today. The engine base for these engines is mainly EA888 and it puts down anywhere from 170-310hp and 207-280lb-ft. The EA888 has three different versions, which means many engine modifications because it wasn’t as reliable as Volkswagen intended. EA888 common engine problems are: High motor oil consumption Stretched timing chain Carbon buildup in intake valves Thermostat housing leak Water pump failure Okay, let’s get to the point. So what is the actual difference between the two? The modifications that were found in the superseded TSI, included 9 different modifications to improve the TFSI’s engine reliability. TSI Engine Modifications Timing chain, instead of a timing belt An upgraded high-pressure fuel pump (hpfp) now located on the camshaft An updated cam follower with a roller, instead of the flat tappet Compression ratio lowered to Different downpipe An added oxygen sensor, now 3 Updated PCV system Relocated the oil filter and dipstick Redesigned engine cover and airbox CCTA vs CBFA Another common question is what is the difference between the CCTA vs CBFA engine code. These engine codes were found in – TSI’s. The CCTA adheres to 49-state emissions vehicles, while the CBFA adheres to California’s emission standards. The main difference between the two is that the CBFA includes: An addition of a secondary air injection pump Relocation of the third oxygen sensor to the turbo turbine outlet Slightly bigger intercooler core and radiator to burn cleaner emissions An additional hose on the airbox As stated above, the CBFA was pretty much made to adhere to California’s rigorous emissions policies. Conclusion & Engine Reliability In conclusion, the two engines are very similar, but the TSI superseded the Turbo FSI and may have had more common problems. These engines are not the most reliable, however, we have seen both of these last longer than 200,000 miles if they are maintained properly.

The major difference between both engines is that the TFSI engines power Audi vehicles, while the TSI engines power VW models. However, both of these engines operate on the same basic principle. The 2.0 FSI, the Volkswagen naturally aspirated engine with direct injection, served as the foundation for the first TFSI engine.2.0 tsi vs 2.0 tdi
