The 2.7 TDI mostly went with models from Ingolstadt ( Audi A4, A5, A6). It is based on 6 cylinders, 24 valves and direct fuel injection common rail (Bosh piezoelectric injectors).
When it comes to equipment, there are turbochargers with variable blade geometry, chain-like drive, floating flywheel and particle filter. The engine is offered in two power variants: 180 and 190 hp.
2.7 TDI engine Problems and malfunctions
It is important to note that the 2.7 TDI is a much more successful engine than the 2.5 TDI, which is considered one of the biggest accidents of the German concern.
However, it is not without several significant shortcomings. Let’s start with the drive. The manufacturer claims that the chain-based system is indestructible.
In practice, however, it turns out that even this solution has a limited lifespan. In the case of this engine, replacement at about 300,000 kilometers is recommended. After all, you can talk about high endurance.
Another thing with the chain as the drive. Both tensioners and chains are relatively expensive elements.
True, operating costs can be a major problem for this engine. Although not too common, its construction is complicated, so a possible replacement involves a lot of money.
Another proof of this condition are the Bosch piezoelectric injectors listed above. Diesel car users often give these elements for regeneration. In the case of the 2.7 TDI, this is not possible as they are virtually irreparable.
