2021 Volkswagen Constellation
The 2021 Volkswagen Constellation is a line of heavy-duty trucks primarily sold in South America and other developing markets. It’s known for its robust build, versatility, and suitability for various commercial applications, including cargo transport, construction, and mining. Engine options typically include a range of diesel engines, such as the Cummins ISL and MAN D08 series, varying in horsepower from around 280 to 360 hp and torque from 950 to 1600 Nm depending on the configuration. Transmission options often include manual and automated manual transmissions (AMT) from ZF and Eaton. While favored for its durability and adaptability, common complaints revolve around parts availability in some regions and the relative simplicity of the interior compared to North American or European trucks.
Engine
Cummins ISL 9.0L Diesel
- Excessive Oil Consumption
- Description/Symptoms: Some owners have reported higher than expected oil consumption, requiring frequent top-offs between scheduled oil changes. Blue smoke may be visible from the exhaust, particularly during acceleration.
- Solution: A thorough inspection is needed to determine the root cause. This could involve replacing valve stem seals, piston rings, or even addressing cylinder wear.
- Estimated Cost to Fix: $1,000 - $5,000+ (depending on the source of the problem and the extent of repairs)
- Recalls: None Found
- Turbocharger Failure
- Description/Symptoms: Loss of power, increased black smoke from the exhaust, and a whistling noise from the turbocharger.
- Solution: Replace the failed turbocharger. It’s essential to identify the cause of the failure to prevent recurrence (e.g., oil starvation, foreign object damage).
- Estimated Cost to Fix: $2,500 - $4,000+
- Recalls: None Found
MAN D08 Diesel
- Fuel Injector Issues
- Description/Symptoms: Rough idling, misfires, reduced power, and increased fuel consumption. Diagnostic trouble codes related to fuel injector performance will likely be present.
- Solution: Diagnose the faulty injector(s) and replace as needed. Ensure proper fuel filtration to prevent future issues.
- Estimated Cost to Fix: $500 - $1,500+ (per injector, plus labor)
- Recalls: None Found
Transmission
ZF AS Tronic Automated Manual Transmission
- Shifting Problems/Harsh Shifting
- Description/Symptoms: The transmission may exhibit harsh or delayed shifts, fail to shift into certain gears, or produce unusual noises during gear changes. Error codes may be stored in the transmission control module (TCM).
- Solution: Diagnose and repair or replace faulty solenoids, sensors, or the valve body within the AMT unit. A software update to the TCM may also be necessary.
- Estimated Cost to Fix: $800 - $3,000+ (depending on the complexity of the issue)
- Recalls: None Found
- Clutch Actuator Failure
- Description/Symptoms: Difficulty engaging or disengaging the clutch, resulting in poor acceleration, stalling, or inability to shift gears.
- Solution: Replace the faulty clutch actuator.
- Estimated Cost to Fix: $1,500 - $3,500+
- Recalls: None Found
Eaton Manual Transmission
- Hard to Shift/Grinding Gears
- Description/Symptoms: Difficulty shifting into gear, grinding noises during shifting, and potential gear lock-up.
- Solution: Inspect and replace worn synchronizers, shift forks, or other internal components. Check clutch linkage for proper adjustment.
- Estimated Cost to Fix: $1,000 - $4,000+ (depending on the extent of the damage)
- Recalls: None Found
Suspension
- Leaf Spring Sagging/Breakage
- Description/Symptoms: The vehicle may sit lower on one side, resulting in poor handling and uneven tire wear. Broken leaf springs are a safety hazard.
- Solution: Replace the worn or broken leaf springs. Consider upgrading to heavy-duty springs if the vehicle is frequently used for heavy loads.
- Estimated Cost to Fix: $500 - $2,000+ (per axle, depending on the spring type and labor)
- Recalls: None Found
Electrical
- Sensor Failures (ABS, Wheel Speed, etc.)
- Description/Symptoms: Warning lights on the dashboard, such as ABS or traction control, may illuminate. Diagnostic trouble codes will be present. These sensor failures can lead to diminished safety performance.
- Solution: Diagnose and replace the faulty sensor(s).
- Estimated Cost to Fix: $200 - $800+ (per sensor, plus labor)
- Recalls: None Found
- Wiring Harness Issues
- Description/Symptoms: Intermittent electrical problems, such as lights flickering, gauges malfunctioning, or starting problems. Corrosion and chafing of wiring harnesses are common causes.
- Solution: Inspect and repair or replace damaged sections of the wiring harness. Ensure proper routing and protection of the harness to prevent future issues.
- Estimated Cost to Fix: $300 - $2,000+ (depending on the location and severity of the damage)
- Recalls: None Found
Exterior
- Rusting (Especially in Coastal Regions)
- Description/Symptoms: Surface rust or more severe corrosion on body panels, frame components, and undercarriage.
- Solution: Remove rust, treat with rust converter, and repaint affected areas. Apply rustproofing undercoating to protect against future corrosion.
- Estimated Cost to Fix: $500 - $5,000+ (depending on the extent of the rust)
- Recalls: None Found
Interior
- Dashboard Cracking
- Description/Symptoms: Cracks appearing on the dashboard surface, particularly in areas exposed to direct sunlight.
- Solution: Replace the dashboard or use a dashboard cover to conceal the cracks.
- Estimated Cost to Fix: $300 - $1,500+ (depending on the complexity of the replacement)
- Recalls: None Found
- HVAC Malfunctions
- Description/Symptoms: Air conditioning not blowing cold, heater not producing heat, or blower motor not functioning properly.
- Solution: Diagnose and repair or replace faulty components, such as the compressor, condenser, evaporator, heater core, blower motor, or control module.
- Estimated Cost to Fix: $200 - $2,000+ (depending on the component that is failing)
- Recalls: None Found
Summary
The 2021 Volkswagen Constellation, while a robust workhorse, faces a range of potential issues. Engine problems can range from moderate oil consumption ($1,000-$5,000+) to more significant turbocharger failures ($2,500-$4,000+). Transmission issues, particularly with the ZF AS Tronic, can be costly ($800-$3,500+). Other areas of concern include suspension, electrical systems, and rust, potentially adding to the overall cost of ownership. While the Constellation is valued for its durability and versatility, potential buyers should be aware of these common problems and factor in potential repair costs.
