Factory defects of TSI and TDI engines
TSI and TDI engines are some of the most technologically advanced power units widely used in cars from VAG brands such as Volkswagen, Audi, Skoda, Seat and Cupra. Despite their modernity and efficiency, certain models in these engine lines may suffer from factory defects. Owners of such vehicles, looking for support, can take advantage of the comprehensive services of VAG Center Kubacki, which provides specialised service and repair for these units.
Typical problems in TSI and TDI engines
What are the most common faults and failures associated with TSI and TDI drive units? Early recognition of problems and their proper diagnosis can prevent more serious damage and costly repairs.
- Timing chain problems in TSI engines
TSI engines, especially in the early 1.2 and 1.4 versions, can exhibit timing chain stretch problems, leading to chain jumping and potentially serious engine damage.
Kubacki’s VAG Center service offers comprehensive fault diagnosis using the advanced ODIS system, which allows us to quickly and accurately identify the problem. In addition, we carry out repairs using original parts, guaranteeing durability and reliability.
- Excessive oil consumption on TSI units
Especially in older TSI engine models, increased oil consumption has been noticed, which can lead to premature wear of engine components and the need for costly repairs.
At VAG Center Kubacki , we carry out major overhauls of drive units, eliminating structural problems and restoring full engine performance. Thanks to our experience in repairs of this type, we offer a guarantee of the highest quality of service.
- Problems with the injection system in TDI engines
Early TDI models with the common rail system exhibited problems with the piezo injectors, which manifested as uneven engine operation and difficulty starting.
At VAG Center Kubacki , we specialise in the diagnosis and repair of injection systems. We use original parts and ensure that repairs are carried out with precision, resulting in longer engine life.
- Diesel Particulate Filter (DPF) in TDI engines
The DPF, although effective in reducing exhaust emissions, can become clogged during short-distance driving. This in turn leads to a decrease in engine power and higher fuel consumption.
VAG Center Kubacki offers professional intake system cleaning and DPF regeneration to restore full exhaust system performance.
