Used car buying guide: Volkswagen Touareg

These and all later versions of the Touareg are four-wheel drive with a manual or automatic locking centre differential (a locking rear diff was an option) and hill descent control. The midlife facelift in 2007heralded no less than 2300 changes, a figure that included boiling down the petrol line-up to one 3.6 V6. The 2.5 and 5.0-litre diesels soldiered on but the 3.0-litre was heavily revised, only to be tinkered with the following year when its power was raised from 221bhp to 236bhp and economy improved by some margin. If you’re shopping for a 2008-reg 3.0 TDI, make sure you check which of the two versions you’re being offered.

For its heated leather seats, satellite navigation and cruise control, SE is the pick of the trims. A clean, 100,000-mile 2008 ‘high-power’ Touareg 3.0 V6 TDI SE with full VW service history for around £5450 is just the ticket.

How to get one in your garage: 

An expert’s view, BARRY BABISTER, CCM VW SPECIALISTS: “We rate the Mk1 Touareg engines. The 3.0 V6 TDI is bulletproof, with the right balance of power and economy. Check that oil and filter changes have been done on time. Oil pressure may be unaffected by poor maintenance and you won’t see the oil light flash but tired oil doesn’t penetrate the engine deeply enough. We see failed timing chain tensioners and bearings so know it’s an issue. Propshaft failure is a talking point. We have a cost-effective repair, but tremors or rumbles could just as easily be poor wheel alignment, which even for an experienced technician is difficult to resolve.”

Buyer beware:

ENGINE - A V10’s DPF light could mean a 13-hour gearbox removal to replace the sensor. On all engines, check for caramelised oil on the block caused by poor injector seating. Variable inlet manifold issues on 3.0 TDIs can trigger limp-home mode; a repair kit is £300. On the 2.5 TDI, check for water pump leaks; on the 3.0 TDI, listen for timing chain rattles. Ignition coil issues hit early petrols.

TRANSMISSION - Check for smooth operation of the auto’ box, although hesitation on V10s and V8s is normal. Check tyres for hard-to-resolve misalignment issues. On cars over 60k miles, thumping when the auto shifts from fifth to fourth could be a failing valve chest (£800 for a specialist fix).

TYRES AND BRAKES - The Touareg’s 2500kg eats discs and pads. Seized calipers and pitted discs are common. Expect just 10,000 miles from tyres. Check the electronic handbrake – repairs are expensive. On older cars with air suspension, check for corroded pipework and the vehicle sitting awkwardly. Listen for steering pump noises on full lock. Check the tyre pressure monitoring system works – it can cause endless trouble.

ELECTRICS - Battery voltage problems can spread throughout the electrics, causing instrument and airbag failures. Check everything works because diagnosis is complex and expensive.

BODY - Corrosion is rare but check for off-road damage underneath.

Also worth knowing:

On a full or trailing throttle, a grumbling noise or a hammer-like banging could be a failing propshaft bearing. It can flare up from around 50k miles. The solution used to be a new shaft but it’s now possible to have the affected parts replaced and the shaft rebuilt.

How much to spend:

£1500-£2995: High-mile 2003-05 2.5 TDIs plus a 2003 5.0 V10 with 150k miles.

£3000-£4995: 2004-07 2.5s, low-power 3.0 TDIs.

£5000-£6995: Early high-power 3.0 TDIs but mostly 06-09 2.5s and sub-100k low-power 3.0 TDIs. Some low-mile 07 3.2 petrols and early, reasonable-mile V10 diesels.

£7000-£8995: More of the same; plenty of circa-100k- mile2009-10high-power 3.0TDIs.

£9000-£11,995: Mainly 2009-10 high-power 3.0 TDIs.

£12,000 AND ABOVE: Most expensive examples topping out at £19k for a 2008 V10 R50.
