What is the 2012-2019 Volkswagen Passat 1.8T/2.0T EA888 Excessive Oil Consumption?
The 2012-2019 Passat with EA888 1.8T and 2.0T engines (North American spec) suffers from excessive oil consumption, often exceeding 1 quart per 1,000 miles. The root cause is typically worn piston rings that allow oil to pass into the combustion chamber. VW released an updated pi… Repairs typically run $200-$4,000. Severity: high.
What is the 2012-2018 Volkswagen Passat 1.8T/2.0T EA888 Timing Chain Stretch?
The EA888 1.8T and 2.0T engines in the 2012-2018 Passat can experience timing chain stretch, particularly in the Gen1 and Gen2 variants. The chain elongates over time due to inadequate tensioner design and oil starvation. This causes camshaft timing to shift, triggering check eng… Repairs typically run $1,000-$2,200. Severity: high.
What is the 2008-2017 Volkswagen Passat Camshaft Adjuster (Phaser) Failure?
The intake camshaft adjuster solenoid and cam phaser on the 2.0T TSI Passat can fail, causing rattling noises and poor engine performance. The cam adjuster uses oil pressure to vary valve timing, and when the internal seals wear or the solenoid sticks, timing control is lost. Thi… Repairs typically run $800-$2,000. Severity: high.
What is the 2008-2017 Volkswagen Passat Timing Chain Tensioner Failure (2.0T TSI)?
The Passat shares the same EA888 2.0T TSI timing chain tensioner issue as other VW/Audi models. The original tensioner design allows the chain to go slack when the engine is off, and on restart the chain can skip timing. Early revisions of the tensioner were inadequate and VW iss… Repairs typically run $1,500-$3,500. Severity: high.
What is the 2012-2015 Volkswagen Passat DPF Clogging (TDI Diesel)?
The diesel particulate filter (DPF) in TDI Passat models is prone to clogging, particularly in vehicles used primarily for short trips or city driving where the exhaust does not get hot enough for passive regeneration. A clogged DPF triggers regeneration cycles that increase fuel… Repairs typically run $300-$3,000. Severity: high.
What is the 2012-2019 Volkswagen Passat DSG Transmission Shudder and Rough Shifting?
The 6-speed DSG (DQ250) in the 2012-2019 Passat develops shuddering during low-speed maneuvers and rough 1-2 and 2-3 shifts. The dual-clutch system's dry or wet clutch packs wear prematurely, and the mechatronic unit can lose calibration. VW recommends DSG fluid changes every 40,… Repairs typically run $300-$3,000. Severity: medium.
What is the 2006-2022 Volkswagen Passat PCV Valve/Diaphragm Failure?
The PCV (Positive Crankcase Ventilation) valve diaphragm in the Passat's 2.0T engine tears or deteriorates over time, causing a significant vacuum leak. This leads to rough idle, misfires, and excessive oil consumption. On TSI engines, the PCV is integrated into the valve cover,… Repairs typically run $200-$800. Severity: medium.
What is the 2006-2022 Volkswagen Passat Trunk Latch/Lock Actuator Failure?
The electric trunk latch actuator on the Passat frequently fails, leaving owners unable to open the trunk with the key fob, interior button, or exterior handle. The actuator motor burns out or the internal mechanism jams. In some cases, the trunk release cable also seizes, leavin… Repairs typically run $150-$400. Severity: low.
