vw 3 cylinder engine problems

The three-cylinder unit was given a block and an aluminum head. What is important, unlike the larger gasoline units of the group, indirect fuel injection is used here – it enables the installation of a gas system. Regular oil and filter changes guarantee smooth operation and cheap operation. In individual cases, there was an increase in the consumption of motor oil, which could be the result of the way the vehicle was used. Users complain about the unpleasant sound of the three-cylinder engine. The unit is still on offer in many models, and its extension is 1.0 TSI.

Similarities to 1.4 TSI

1.0 MPI / TSI engines have cylinders of identical diameters as the 1.4 TSI, but the 1.0 MPI / TSI has three cylinders. Simply put, 1.0 MPI / TSI engines were made after removing a single cylinder. In order to reduce production costs and increase unification, cylinders of the same diameter as in 1.4 TSI were used. This allows the same settings to be used for many production machines in production facilities. One of the specific solutions of the 1.0 MPI / TSI engine is a valve cover that is integrated with the camshafts, which can make it difficult or impossible to replace their bearings (fortunately, this is rarely necessary in properly designed units).

1.0 TSI engine – Debut 2015

The 1.0 TSI engine based on the 1.0 MPI was introduced in 2015. It was based on the construction of a weaker atmospheric engine, adding numerous elements to increase engine efficiency. One of the most serious modifications is the replacement of simple indirect fuel injection with direct fuel injection. Turbocharging provides a significant increase in power and, above all, flexibility. The engine, which weighed a modest 93 kg, quickly came under the hood of Škoda Octavia, Fabia, Seat Ibiza, Leon and many other models of the group. Depending on the variant, the engine produces 82, 86, 90, 95, 110 and 115 hp and a torque of 160-200 Nm. Interestingly, even the relatively heavy Octavia handles this engine well in everyday work. There is no lack of strength in city driving. The power problem only starts at higher speeds. Currently, experts do not report excessive engine oil consumption, similar to larger TSI family units. Dosing of 0,2-0,3 liters is not a cause for concern.

Quiet work

We won’t worry too much about the high-pressure injection system – 200 bar. For now, little is known about the power of turbochargers with fixed blade geometry. However, it can be assumed that his driving style and regular servicing have a huge impact on his life.
In addition to the vibrations typical of three-cylinder engines, we also have to get used to the heavy, resilient work that is typical of the TSI engine family
The switching mechanism is the most interesting. The manufacturer has defined the life of a gear belt working in it for over 200.000. km, recommending only prior inspections of the gear belt condition (with the introduction of the engine it was even said that the lifespan represents the assumed operating period of the vehicle). It is worth shortening the time between the timing belt replacement.
Most vibrations that accompany the operation of a three-cylinder engine are absorbed by the pillows. You will need to replace them faster than in cars with larger engines.

1.0 TSI engine – Segment A to C

The 1.0 TSI quickly gained popularity and began to reach most of the company’s models. No wonder, because it offers good parameters with a reasonable demand for fuel. In Fabia, it can consume about 6,5 liters in the city and less than 5 on the highway. The situation is even better in VW Up! It also provides very good performance. The 115-horsepower Polo accelerates to 9 km / h in just over 200 seconds and accelerates to over 8 km / h. The situation is somewhat worse in the Golf or Karoqu, where they feel a lack of power on the highway. It also increases fuel consumption to about 9-XNUMX liters.

1.0 TSI can be found in the following group models:

  • VW – Up !, Polo, Golf, T-Roc, T-Cross
  • Škoda – Fabia, Octavia, Karoq
  • Seat – Ibiza, Arona, Ateca
  • Audi – A1, A3, K2
