• Oil filter housing gasket leak: Causes oil to leak from the oil filter housing, leading to low oil levels and possible engine damage. Symptoms include an oil puddle under the vehicle and a burning oil smell. Solution: Replace the oil filter housing gasket. Estimated Cost to Fix: $200 - $400.
• Intake manifold runner flap failure: Causes the intake manifold runner flaps to stick or break, reducing airflow into the engine. Symptoms include decreased power, rough idle, and increased emissions. Solution: Replace the intake manifold runner flaps. Estimated Cost to Fix: $800 - $1,500.

5.0L V10

• Cylinder head gasket failure: Causes coolant and oil to leak into the combustion chambers, leading to overheating and engine damage. Symptoms include white smoke from the exhaust, low coolant levels, and a rough idle. Solution: Replace the cylinder head gaskets. Estimated Cost to Fix: $4,000 - $6,000+.
• Ignition coil failure: Causes misfires, reduced power, and possible engine damage. Symptoms include a rough idle, loss of power, and the engine not starting. Solution: Replace the ignition coils. Estimated Cost to Fix: $300 - $600.
• Oil consumption: Consumes excessive amounts of oil, requiring frequent top-ups. Symptoms include low oil levels on the dipstick and oil smoke from the exhaust. Solution: Replace the piston rings or rebuild the engine. Estimated Cost to Fix: $3,000 - $6,000+.

Transmission

6-speed Manual

• Clutch failure: Causes difficulty shifting gears, slipping, or the inability to engage gears. Symptoms include a grinding noise when shifting, difficulty getting the vehicle moving from a stop, and the clutch pedal feeling spongy. Solution: Replace the clutch assembly. Estimated Cost to Fix: $1,000 - $2,000.
• Transmission oil leak: Causes transmission fluid to leak from the transmission case, leading to low fluid levels and possible transmission damage. Symptoms include an oil puddle under the vehicle and difficulty shifting gears. Solution: Replace the transmission oil seals or gaskets. Estimated Cost to Fix: $200 - $600.

6-speed Automatic

• Valve body failure: Causes erratic shifting, delayed engagement, or the inability to shift gears. Symptoms include rough shifting, slipping, or the vehicle not moving. Solution: Replace the valve body. Estimated Cost to Fix: $1,200 - $2,000.
• Torque converter failure: Causes shuddering, slipping, or overheating of the transmission. Symptoms include a vibration when shifting gears, reduced power, and difficulty accelerating. Solution: Replace the torque converter. Estimated Cost to Fix: $1,500 - $3,000.

8-speed Automatic

• Mechatronic unit failure: Causes gear shifting issues, transmission overheating, or the inability to drive the vehicle. Symptoms include a warning light on the dashboard, rough shifting, or the vehicle not moving. Solution: Replace the mechatronic unit. Estimated Cost to Fix: $2,000 - $4,000.
• Transmission fluid leak: Causes transmission fluid to leak from the transmission case, leading to low fluid levels and possible transmission damage. Symptoms include an oil puddle under the vehicle and difficulty shifting gears. Solution: Replace the transmission oil seals or gaskets. Estimated Cost to Fix: $200 - $600.

Suspension

• Front lower control arm bushings failure: Causes clunking or rattling noises from the front suspension, excessive tire wear, and poor handling. Symptoms include a loud noise when driving over bumps, uneven tire wear, and difficulty keeping the vehicle in a straight line. Solution: Replace the front lower control arm bushings. Estimated Cost to Fix: $400 - $800.
• Rear air suspension compressor failure: Causes the rear suspension to sag, reducing ride height and handling. Symptoms include a lowered rear suspension, difficulty adjusting the ride height, and a warning light on the dashboard. Solution: Replace the rear air suspension compressor. Estimated Cost to Fix: $1,200 - $1,800.

Electrical

• Battery drain: Causes the battery to discharge quickly, leading to difficulty starting the vehicle or power loss while driving. Symptoms include a weak or dead battery, difficulty starting the vehicle, and electrical components not working properly. Solution: Diagnose and resolve the cause of the battery drain. Estimated Cost to Fix: Varies depending on the cause.
• Alternator failure: Causes the vehicle to lose power and the battery to discharge. Symptoms include a warning light on the dashboard, flickering headlights, and difficulty starting the vehicle. Solution: Replace the alternator. Estimated Cost to Fix: $500 - $1,000.

Exterior

• Headlight reflector oxidation: Causes the headlight reflectors to become hazy or discolored, reducing visibility at night. Symptoms include dim headlights and difficulty seeing at night. Solution: Replace the headlight assemblies. Estimated Cost to Fix: $800 - $1,200.

Interior

• Climate control panel failure: Causes the climate control system to malfunction, leading to difficulty adjusting the temperature or fan speed. Symptoms include erratic operation of the climate control system, incorrect temperature readings, and difficulty defogging the windshield. Solution: Replace the climate control panel. Estimated Cost to Fix: $500 - $1,000.
• Infotainment system software issues: Causes the infotainment system to freeze, crash, or display error messages. Symptoms include a blank or flickering screen, difficulty using certain features, and loss of radio reception. Solution: Update the infotainment system software. Estimated Cost to Fix: Free if under warranty, otherwise $100 - $200.

Summary:

The 2007 Volkswagen Touareg is known for its rugged capabilities, spacious interior, and powerful engine options. However, it has been plagued with a range of issues that can be costly to repair. The most severe issues include engine timing chain tensioner failure, ignition coil failure (5.0L V10), valve body failure, mechatronic unit failure, and battery drain. Some issues, such as coil pack failure and oil filter housing gasket leak, are relatively minor and inexpensive to fix. Overall, the reliability of the 2007 Volkswagen Touareg is below average, with owners reporting a higher than average number of repairs.
