Build my inspection planFrequently asked questions
Is the Touareg a good used buy?
Yes when it has motorway miles and full history.
What to avoid?
Low mileage urban cars with clogged DPFs.
Any towing checks?
Look for a towbar and check the brakes and gearbox oil history.
When do the timing chains need replacing on the 3.0 V6 TDI?
The 3.0 V6 TDI uses a timing chain designed to last the life of the engine, so there is no set replacement interval. However, tensioner wear can occur at higher mileages. Listen for a pronounced rattle on a cold start. If the chain stretches, replacement is an engine-out job, making it highly labour-intensive.
Does the 4Motion system require Haldex oil changes?
No. Unlike smaller Volkswagen models, the Touareg uses a permanent four-wheel-drive system with a Torsen mechanical centre differential, not a Haldex clutch. While Volkswagen claims the transfer box fluid is filled for life, specialists highly recommend changing this fluid every 60,000 miles to prevent low-speed binding and drivetrain judder.
Are there any common issues with the AdBlue system?
The SCR system is generally robust, but the AdBlue injector nozzle can crystallise and block if poor-quality fluid is used or if the car sits idle for extended periods. This triggers an engine management light and a countdown to a non-start condition. Always ensure the system is topped up with fresh fluid.
