Volkswagen Touran Mk2 (5T) Common Problems & Reliability
The Mk2 Volkswagen Touran (5T) is one of the most sensible, practical seven-seat MPVs sold in the UK, underpinned by the versatile MQB platform. It serves as a spacious and premium family hauler, sitting above the Golf Estate but below the larger Sharan, offering reasonable running costs and solid residual values. Because it shares familiar hardware with the Golf and Tiguan, reliability depends heavily on strict adherence to cambelt, DSG, and Haldex service schedules. It perfectly suits growing families who need maximum interior flexibility without the bulky footprint of a large SUV.
