The 2014 Volkswagen Passat TDI offers a spacious interior, comfortable ride, and impressive fuel economy. However, this model year has also been associated with several potential problems. This article outlines some common issues reported by 2014 VW Passat TDI owners and mechanics.
Engine and Emissions System Problems
One of the most significant concerns with the 2014 Passat TDI is its complex emissions control system. This system is prone to issues, particularly with the CKRA turbocharger. This turbocharger was known to be weak and prone to failure, leading to a warranty extension. Even after fixes, injector balance and SCR (Selective Catalytic Reduction) problems persist. DEF (Diesel Exhaust Fluid) tank heater failures were also common, leading to further warranty extensions.
Heater Core Issues
Clogged heater cores were a problem even before fixes were implemented, and the issue seems to have worsened. Fortunately, the heater core can be replaced without removing the entire dashboard, making the repair somewhat less labor-intensive.
Suspension Concerns
Compliance bushings in the control arms are another common point of failure in the 2014 Passat TDI. These bushings often require replacement before the vehicle even reaches 80,000 miles.
General Reliability Compared to Older Models
While the 2014 Passat TDI offers modern amenities and a larger size compared to older models like the ALH, it may not offer the same long-term reliability and ease of maintenance. Many mechanics report that these newer models experience more frequent and costly repairs, even before reaching 100,000 miles, compared to older TDIs that often run well past 300,000 miles. Some attribute this to cost-cutting measures that have resulted in lower quality components. For example, the trunk hinges, springs, and stamped steel subframe are often cited as feeling cheap and reminiscent of other non-European brands. Even seemingly minor components, like the Chinese-made HVAC door motors, are prone to failure.
Conclusion
The 2014 VW Passat TDI can be a comfortable and fuel-efficient car. However, potential buyers should be aware of the potential problems outlined above. The complex emissions system, turbocharger issues, heater core problems, and suspension concerns can lead to costly repairs. While not necessarily a “bad” car, the 2014 Passat TDI may not offer the same long-term reliability and low maintenance costs as older TDI models. Careful consideration of these issues is recommended before purchasing a 2014 VW Passat TDI.
