What is the 2008-2013 Volkswagen Jetta High-Pressure Fuel Pump (HPFP) Failure?

Early TSI engines can experience high-pressure fuel pump (HPFP) cam follower wear, leading to fuel system issues. The cam follower rides on the fuel pump lobe and can wear through, causing metal contamination and pump failure. Repairs typically run $150-$1,500. Severity: high.

What is the 2008-2019 Volkswagen Jetta Turbocharger Failure/Wastegate Rattle?

The turbocharger can fail due to oil starvation, wastegate wear, or bearing failure. Wastegate rattle is common on IHI turbos used in earlier models. Turbo failure can send debris into the engine. Repairs typically run $800-$2,500. Severity: high.

What is the 2000-2003 Volkswagen Jetta Airbag Warning Light, Crash Sensor, and Non-Deployment Concerns?

What is the 2000-2001 Volkswagen Jetta ABS Control Module and Low-Speed False ABS Activation?

Complaint data show a recurring pattern of ABS warning lights, chimes, and unexpected ABS activation at low speeds, sometimes causing longer stopping distances or abrupt brake behavior. The issue is reinforced by a recall covering short circuits within the ABS electronic control… Repairs typically run $150-$1,200. Severity: high.

What is the 2000-2004 Volkswagen Jetta Fuel Pump and Fuel Leak Stalling Issues?

Several complaints describe the Jetta suddenly stalling in traffic, failing to restart, or leaking gasoline or diesel fuel. The pattern includes fuel pump-related shutdowns and diesel pump leakage concerns, creating both drivability and fire-safety risks. Repairs typically run $300-$1,400. Severity: high.

What is the 2019 Volkswagen Jetta Rear Axle Coil Springs May Fracture - Two NHTSA Recalls on the Mk7 Jetta?

Volkswagen recalled the 2019 Jetta twice for rear axle coil springs that can fracture prematurely.

Severity: high.

What is the 2004-2006 Volkswagen Jetta BEW/BRM Pumpe Duse Camshaft Lobe Wear Driven by a Weakening Tandem Pump?

The 2004-2006 Jetta TDI's Pumpe Duse (unit-injector) 1.9 TDI - BEW in the Mk4/Mk4.5 and BRM in the Mk5 - wears out its camshaft, and the mechanism is specific to this engine family. The camshaft carries the injector lobes, which see enormous loads because each unit injector is me… Repairs typically run $1,200-$3,500. Severity: high.

What is the 1999-2005 Volkswagen Jetta 01M Four-Speed Automatic Transmission Valve Body and Solenoid Harness Failure?

Mk4 Jettas ordered with the 01M/AG4 four-speed automatic (1999-2005, behind the 2.0 ABA/AVH, 1.9 TDI ALH and VR6) commonly suffer valve body and internal wiring-harness failure. The solenoid pack's internal harness (01M325283A) and the shift solenoids themselves degrade, producin… Repairs typically run $600-$2,800. Severity: high.

What is the 1995-1999 Volkswagen Jetta VR6 Timing Chain Guide and Tensioner Rattle (Rear of Engine)?

The 12-valve VR6 uses timing chains at the REAR (transmission side) of the engine, and its plastic chain guides and tensioners become brittle and break as mileage passes ~100k. The classic warning is a rattle from the driver's side of the engine at roughly 1000-1200 RPM (often de… Repairs typically run $400-$2,000. Severity: high.

What is the 1996-1999 Volkswagen Jetta 1.9 TDI Timing Belt Failure on an Interference Engine (Short Original Interval)?

The MK3 1.9L TDI (AHU/1Z, US 1996-1999) is a belt-driven interference diesel: if the timing belt, tensioner, or idler bearing fails, the valves collide with the pistons and destroy the cylinder head. The original factory replacement interval for this era engine was short (about 6… Repairs typically run $500-$1,200. Severity: high.

What is the 2008-2019 Volkswagen Jetta Water Pump/Thermostat Housing Failure?

The plastic water pump and thermostat housing are prone to cracking and leaking. The impeller inside the water pump can also degrade. This is a common failure point on the EA888 engine, often occurring between 60,000-100,000 miles. Repairs typically run $400-$1,200. Severity: medium.

What is the 2008-2021 Volkswagen Jetta Intake Valve Carbon Buildup?

Direct injection engines like the 2.0T TSI don't have fuel washing over the intake valves, leading to carbon buildup over time. This restricts airflow and causes performance issues. Typically becomes noticeable after 60,000-80,000 miles. Repairs typically run $400-$800. Severity: medium.

What is the 2008-2015 Volkswagen Jetta PCV Valve/Diaphragm Failure?

The PCV (Positive Crankcase Ventilation) system can fail, causing rough idle, oil leaks, and check engine lights. The diaphragm inside the valve cover can tear, leading to boost leaks and oil consumption. This is common on early TSI engines. Repairs typically run $200-$600. Severity: medium.
