VW Touareg 3.0 TDI Review – Problems and Maintenance

If you've been searching for "VW Touareg 3.0 TDI 245 reviews", "Touareg 3.0 TDI 262 reviews" or "Touareg 3.0 TDI 224 reviews", you're probably wondering which engine is best and what sort of trouble it might give you. I get it. The Touareg is a big, tough and incredibly comfortable car that can handle some serious work. But looking after one isn't something to take lightly. There are three generations – the 7L (2002–2010), 7P (2010–2018) and CR (from 2018) – and each has its own quirks. In this VW Touareg 3.0 TDI review, I'll walk you through what I look for on these cars and why the cheapest Touareg in the classifieds can sometimes turn out to be the most expensive.

Who is the VW Touareg 3.0 TDI right for?

If you tow a trailer, head into the mountains, drive on rough roads or cover a lot of miles, the Touareg is definitely worth a look. That big V6 diesel is made for exactly this sort of work, and the comfort is one of the reasons people love these cars. But here's the thing! You're driving a big car with a six-cylinder engine, an automatic gearbox and four-wheel drive. If you think you can maintain it like a Golf, you're in for a disappointment. Regular servicing isn't something you can keep putting off with a Touareg.

Which engines and gearboxes does the Touareg have?

There are different 3.0 TDI engines across the three generations, so don't settle for the seller telling you it's a six-cylinder diesel. You need to know which generation you're looking at, exactly which engine it has and how the car has been maintained. Here are the main versions.

• VW Touareg 7L (2002–2010) – 3.0 TDI with 224 or 240 hp, paired with a 6-speed Tiptronic automatic gearbox.
• VW Touareg 7P (2010–2018) – 3.0 TDI with 204, 245 or 262 hp and an 8-speed Tiptronic gearbox.
• VW Touareg CR (from 2018) – 3.0 TDI with 231 or 286 hp.
• 4MOTION – four-wheel drive, with air suspension fitted to some cars.

I wouldn't choose one just by looking at the horsepower. I'm far more interested in whether the car has been properly looked after and whether it's hiding any problems. A well-maintained Touareg can be a much better buy than a more powerful one with no record of what's been done to it.

VW Touareg 3.0 TDI review: what problems do we see?

There are a few things on the Touareg that I always check very carefully. That doesn't mean every car will suffer from all of them. I just want you to know what to look out for when you're buying. Otherwise, you might not discover these problems until you're the one paying the repair bills.

Engine timing chains

On the 3.0 TDI, the timing chains are at the back of the engine, and the tensioners and guides are among the things we always check. If you hear a rattling noise on a cold start, don't accept someone telling you that all diesels sound like that. We listen carefully and check the engine timing synchronisation with diagnostics. Replacing the timing chains is a major job because the engine has to come out. I've explained exactly why in my article 3.0 TDI: why the engine has to come out to replace the timing chains.

Air suspension

Air suspension makes the Touareg incredibly comfortable, but when it starts playing up, the repairs are no small matter. If the car sinks after being parked or the compressor runs for far too long, don't treat that as normal. We need to find out where it's losing height and whether the compressor is working properly. I've explained more in my article about air suspension problems.

Swirl flaps, EGR, DPF and AdBlue

Now we're talking about the air going into the engine, the exhaust gases coming out and the systems that clean them up. The swirl flaps direct the airflow into the engine, the EGR valve sends some exhaust gases back through it, and the DPF traps soot. When one of these stops working properly, the car can lose power and the engine warning light can come on. On the newer Euro 6 versions, you've also got AdBlue, which can bring its own headaches. But we don't guess what's wrong just because a warning light has appeared. We run diagnostics and find the actual cause.

Tiptronic gearbox, transfer case and differentials

If the automatic gearbox bangs into gear, jerks or changes gear too late, the first things I look at are its condition and when it was last serviced. Old gearbox oil isn't something you can just ignore. And besides the Tiptronic, you've got a transfer case that sends drive to both axles, plus the differentials. They have oils that need checking too. Don't get so focused on the engine that you forget everything else. The whole drivetrain needs to be in good condition.

What should I check before buying a Touareg 3.0 TDI?

I wouldn't buy a Touareg after nothing more than a quick spin around the dealer's forecourt. The car might look brand new while hiding some very expensive repairs underneath. That's why the inspection needs to be thorough and systematic. It's not enough to plug in a diagnostic tool, see no fault codes and call it a day.

1. Cold start – we listen for timing chain rattles and check the engine timing synchronisation with a diagnostic tool.
2. Air suspension – we check whether the car sinks after being parked overnight and how the compressor operates.
3. Tiptronic – we test how the gearbox changes gear both cold and fully warmed up.
4. Leaks and drivetrain – we inspect the engine from above and below, the transfer case and all the other important areas.

That's exactly what we do during our pre-purchase inspection. I want you to know what you're buying before you hand over your money. Because afterwards, it's a bit late to start wondering whether those timing chains were already rattling when the seller had the car.

How should I service my VW Touareg 3.0 TDI?

With a car like this, don't wait for something to break before visiting the workshop. Keep up with regular servicing and don't put off oil changes. Here are the service intervals we follow at Das Auto Service.

• Engine oil and filters – every 10,000 km or once a year, whichever comes first. It doesn't matter which oil you use or what the LongLife service intervals say.
• Tiptronic, transfer case and differentials – we service them together every 90,000 km. After changing the automatic gearbox oil, we always carry out an adaptation.
• Brake fluid – every 2 years.
• Coolant – every third heating season.
• Workshop inspection – every 6 months, so we can catch problems early.

If you want to see exactly what needs servicing on each generation, have a look at the Touareg 7P 3.0 TDI service schedule and the Touareg CR 3.0 TDI service schedule. That way, you'll know exactly what needs doing and when.

Is the Touareg 3.0 TDI worth buying in my opinion?

Yes, absolutely, as long as you know what you're buying. The Touareg 3.0 TDI is a fantastic workhorse – comfortable, tough and ready for serious driving, provided it has a proper service history and the timing chains, suspension and drivetrain have all been checked. I wouldn't walk away from a good Touareg just because it costs more to maintain. But! That "cheap Touareg" with no paperwork can very easily become the most expensive car you've ever bought. That's why, for me, condition always matters more than price.

Advice from Kris Mladenov: If you've got your eye on a Touareg 3.0 TDI, set aside some money for the timing chains and air suspension before you even buy it. Check the service history and don't skip the diagnostics. If the car has been properly looked after, there's every chance it'll serve you well for a long time.

I hope I've helped you out! If I have, share this article with a friend who drives a Touareg or is thinking about buying one. I've always believed that when I know something useful, there's no reason to keep it to myself. That's why I share what I've learnt in the workshop with you.

Frequently asked questions

Which Touareg 3.0 TDI is the best?

Don't choose purely on whether it has 224, 245, 262 or 286 hp. What matters more to me is a clear service history, timing chains that have been checked and suspension that's in good condition.

What are the most common problems with the Touareg 3.0 TDI?

We check the timing chains, air suspension, swirl flaps, EGR valve, DPF, AdBlue system and automatic gearbox. We don't overlook the transfer case or differentials either.

How long do the timing chains last on a Touareg 3.0 TDI?

I'm not going to promise you a particular mileage. First, we listen to the engine from cold and check the timing synchronisation with diagnostics. Only then do we draw any conclusions.

How often should the Tiptronic gearbox oil be changed?

For the Touareg, I recommend every 90,000 km, along with the transfer case and differential oils. We always carry out a gearbox adaptation after changing the automatic gearbox oil.
