Faults a 2018 example has usually reached

Documented onset mileage is at or below the ~108k miles an average 2018 car has covered.

SuspensionHigh

Air suspension leaks and compressor failure

Typically appears
70,000+ miles
What to inspect
Cycle the ride height settings and listen to the compressor
EngineHigh

EGR cooler and DPF faults on short journey cars

Typically appears
80,000+ miles
What to inspect
Check the service history for short trip use and run it hot
BrakesMedium

Warped discs from towing use

Typically appears
40,000+ miles
What to inspect
Brake firmly from speed and feel for pedal pulsing
EngineHigh

Coolant loss and sweet smell from engine bay due to water pump or thermostat housing leaks.

Typically appears
40,000-70,000 miles
What to inspect
Remove the acoustic engine cover and shine a torch down into the engine V-valley. Look for pooled pink coolant or crusty white/pink residue.

Drivetrain judder, binding, or groaning noise from the centre differential when turning on full lock.

Typically appears
50,000-80,000 miles
What to inspect
Drive the vehicle in tight figure-of-eight circles on the forecourt at idle speed. Feel for vibration, skipping, or binding through the floorpan and steering wheel.

Faults that appear at any mileage

What to inspect
Test the full width display and all haptic controls
BodyMedium

Water ingress into the cabin due to blocked panoramic sunroof drains or distorted frame seals.

Typically appears
3-5 years
What to inspect
Press firmly into the front and rear footwell carpets to check for dampness. Inspect the headliner edges and A-pillars for water tide marks.

Volkswagen Touareg · frequently 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.
