VW Passat B6 Variant engines
The VW Passat B6 Variant was introduced in 2005 as the estate version of the sixth Passat generation and quickly established itself as one of the most successful mid-size estate cars in Europe. Over the production period from 2005 to 2010, Volkswagen offered an impressive variety of engine options, ranging from economical diesel units to powerful V6 engines. This range of engines reflected the technological changes of the time and set new standards in terms of efficiency and performance.
VW Passat B6 Variant engines - modern efficiency and proven technology (2005-2010)

The B6 generation of the Passat Variant marked an important turning point in Volkswagen's engine development. With a typical mileage of 250,000 to 350,000 kilometers, most engines proved to be extremely durable. Major repairs were usually only due after 200,000 kilometers, with the 2.0 TDI with 140 PS (BMP engine) being considered the absolute highlight of the generation. This generation of engines introduced modern common-rail diesel technology and TSI petrol engines, while at the same time proven V6 units rounded off the top end of the range. Compared to rivals such as the BMW 3 Series Touring or Audi A4 Avant, the Passat B6 Variant offered a more balanced mix of comfort, efficiency and reliability.
VW Passat B6 Variant TSI petrol engines (2005-2010)
The TSI engine family revolutionized the Passat B6 Variant's petrol engine range with its combination of turbocharging and direct injection. The 1.4 TSI with 122 PS (CAXA) established itself as the entry-level engine and impressed with its low fuel consumption of around 6.5 liters per 100 kilometers. However, the timing chains proved to be problematic, as they can be due for replacement after just 100,000 kilometers. The 1.8 TSI with 160 PS (BZB/CDAA) offered balanced power delivery, but suffered from occasional problems with the high-pressure pumps from around 150,000 kilometers. The most powerful petrol variant was the 2.0 TSI with 200 PS (BWA/CCTA), which impressed with its sporty characteristics, but frequently developed problems with the piston rings due to the high thermal load.
VW Passat B6 Variant FSI petrol engines (2005-2008)
The FSI engines represented Volkswagen's first step towards direct injection before the introduction of TSI technology. The 1.6 FSI with 115 PS (BLF) served as the basic engine and was characterized by its simple design, but struggled with problems with the injection valves, which often had to be cleaned after just 80,000 kilometers. The 2.0 FSI with 150 PS (BVY/BVZ) offered solid performance, but was prone to coking in the intake tract due to direct injection without additional intake manifold injection. These engines were replaced by the more modern TSI units in 2008, as they no longer met the increasing efficiency requirements.
VW Passat B6 Variant V6 petrol engines (2005-2010)
The V6 engine family crowned the Passat B6 Variant's petrol engine range with two different concepts. The 3.2 V6 FSI with 250 hp (BDB/AXZ) combined naturally aspirated engine technology with direct injection and offered cultivated power delivery and a characteristic engine sound. Despite the high fuel consumption of around 10 liters per 100 kilometers, this engine proved to be very reliable and often achieved mileages of over 300,000 kilometers without any major problems. The top-of-the-range engine was the 3.6 V6 FSI with 300 hp (BWS), which was only available in the 4Motion version and impressed with its impressive power delivery, but caused higher maintenance costs due to its more complex technology.
VW Passat B6 Variant TDI diesel engines (2005-2010)
The TDI engine family formed the backbone of the Passat B6 Variant range and impressed with a wide power spread from 105 to 240 hp. The 1.9 TDI with 105 PS (BXE/BLS) was the entry-level engine and was considered one of the most reliable diesel engines of its time, regularly achieving mileages of over 400,000 kilometers and only requiring regular maintenance of the injection nozzles every 100,000 kilometers. The 2.0 TDI was available in various power levels: 136 hp (BKD), 140 hp (BMP) and 170 hp (BMR/BVD). The 140 hp engine (BMP) in particular established itself as the reference for long-distance drivers, as it offered an optimum compromise between performance, consumption and reliability. The 2.0 TDI with 170 hp, on the other hand, was prone to problems with the exhaust gas recirculation valve from around 120,000 kilometers.
The V6 TDI engines with displacements of 2.5 and 3.0 liters served as the top-of-the-range units. The 2.5 TDI V6 with 163 hp (BDG/BDH) impressed with its smooth running and pulling power, but occasionally had problems with the glow plugs in the cold season. The 3.0 TDI V6 was available in two power levels: 224 hp (BMK/BKS) and 240 hp (BMY). Both engines impressed with their impressive power delivery and characteristic V6 sound, but caused higher maintenance costs due to the more complex technology.
