Summary

The 2005 Volkswagen Touareg, while offering a luxurious and capable driving experience, is known for a variety of potential issues. Engine problems range from relatively minor issues like ignition coil failures to more significant concerns like timing chain tensioner problems in the V8 and turbocharger failures in the V10 TDI. The 6-speed automatic transmission can suffer from valve body and torque converter issues. Suspension issues, particularly with the air suspension system (if equipped), can be costly to repair. Electrical gremlins, including battery drain and module failures, are also common complaints. The V10 TDI, while powerful, tends to have the most expensive repairs due to its complex design. Overall, potential owners should be aware of the high maintenance costs associated with this vehicle, particularly concerning the V8 and V10 TDI models.
