DSG vs S tronic vs Tiptronic: What's the Difference?

You're looking at used car adverts. One says S tronic, another says DSG, and a third says Tiptronic. They're all automatic gearboxes, right? Yes, but they're definitely not the same! I hear this all the time at the workshop: "Kris, it's an automatic. Does it really matter which gearbox it has?" Trust me, mate, it matters a lot. Behind those names are completely different gearboxes. They work differently, need different servicing and can give you very different headaches when something goes wrong. I'll explain what each one does, so you know exactly what you're driving or thinking of buying.

What is DSG, and why does it change gear so quickly?

DSG is Volkswagen's name for its dual-clutch automatic gearbox. Imagine having two gearboxes working together inside one unit. While you're driving in one gear, the next gear is already selected and waiting. When it's time to change, one clutch lets go and the other takes over. That's why a DSG can change gear so quickly that you sometimes barely notice it happening.

But not all DSG gearboxes are the same. There's the DQ200 with dry clutches, and the DQ250, DQ381 and DQ500 with wet clutches that run in oil. They're built differently, and you really need to know which one is fitted to your car. If someone tells you that all DSG gearboxes are identical, don't believe them. And when you hear someone say their gearbox is jerking or juddering when pulling away, don't assume every DSG has the same problem. First, we need to know exactly which gearbox we're dealing with.

Is S tronic the same as DSG?

Yes, S tronic is also a dual-clutch automatic gearbox. It's simply the name Audi uses. In cars like the Audi A3, Q3 and TT, we're talking about the same family of gearboxes as Volkswagen's DSG. The principle is identical: two clutches, the next gear ready to go and very quick gear changes. The name is different, but the exact gearbox depends on the car. So far, nice and simple.

But here's where things change! In Audi A4, A5, A6 and Q5 models with a longitudinal engine, meaning the engine sits lengthways in the car, you'll find different gearboxes, such as the DL501 and DL382. They're still called S tronic and still have two clutches, but they're built differently. So you can't read something about the DSG in a Golf and assume it applies exactly to your Audi A6. If you'd like to understand this gearbox better, have a read of my article on S tronic 0B5, DL501 and the mechatronic unit. I've explained what's going on inside in much more detail.

What is Tiptronic, and how is it different?

Tiptronic is a traditional automatic gearbox with a torque converter. I know that sounds technical, but it's actually quite easy to understand. Instead of the two clutches you get in DSG and S tronic, it uses a torque converter to transfer power from the engine to the gearbox through oil. It's a completely different way of doing the same job. The gearbox chooses the gears automatically, but you can also change them yourself whenever you want. So Tiptronic doesn't simply mean "an automatic where I can change gears manually".

You'll find these gearboxes in cars such as the Audi A6, A8 and Q7, Volkswagen Touareg and Porsche Cayenne. Depending on the car, they're made by ZF or Aisin. And once again, there are different designs, so don't assume every Tiptronic is identical. Knowing exactly which one you have is particularly important when it's time for a service. I've written a separate article about the ZF 8HP: ZF 8HP Tiptronic – when does it need servicing?.

What is Multitronic, and why is it different?

Multitronic is another type of automatic gearbox you'll find in older front-wheel-drive Audi models. It's a continuously variable transmission, or CVT, which means it doesn't have the usual fixed gears you get with DSG or Tiptronic. Instead of changing from one gear to another in the normal way, it smoothly adjusts the gear ratio as you drive. That's why it feels different behind the wheel. It's not DSG, it's not S tronic, and it's not a traditional Tiptronic either.

This is where a lot of people get confused, especially when buying an older Audi. The advert just says "automatic", and nobody explains what type it actually is. Then the new owner turns up at the workshop saying, "It keeps juddering, but aren't all automatics like that?" No, my friend, they're not. If you own one of these cars or you're thinking of buying one, read my article on why Multitronic judders and whether it can be repaired. It's much better to know what you're getting into before you buy than to find out afterwards.

When should you change DSG, S tronic and Tiptronic oil?

Now, this is the part I really want you to pay attention to. Different gearboxes have different service intervals, and gearbox oil isn't something you should only think about when the car starts jerking. At Das Auto Service, we follow specific intervals based on the gearbox and the car it's fitted to. I want you to know these intervals too, because looking after your gearbox is part of looking after your car. And believe me, it's worth doing properly.

• DSG and S tronic – all versions are serviced every 60,000 km using genuine oil.
• Tiptronic in Audi A-series models – every 120,000 km. For S/RS models and hybrids, every 80,000 km.
• Tiptronic in the Audi Q5 – every 120,000 km.
• Tiptronic in the Touareg, Q7, Q8 and Cayenne – every 90,000 km, together with the transfer case and differential oils.
• Multitronic – every 60,000 km using genuine oil.
• Automatic gearboxes in the VW Golf, Passat, Tiguan and Transporter – as prescribed by the manufacturer and, at our workshop, based on inspection.
• Front differentials and transfer cases are serviced at the same time as the gearbox oil.
• After every automatic gearbox service, we carry out an adaptation procedure. Every single time.

Adaptation is a procedure that makes sure the gearbox electronics are set up to work properly after servicing. It's not just a case of changing the oil, tightening the drain plug and handing your keys back. Your gearbox has its own little "brain" that controls the gear changes, and that needs the correct procedure too. That's why a proper gearbox service doesn't end when the fresh oil goes in.

Which oil and parts should you use for a gearbox service?

For me, a proper service starts with the correct oil and the right parts for your exact gearbox. Don't choose an oil just because the bottle says it's suitable for automatic transmissions. First, you need to know which gearbox your car actually has. Here are the genuine products for the different types of gearbox service.

Tip from Kris Mladenov: Don't buy a car just because the advert says "automatic". Ask exactly which gearbox it has and when it was last serviced. If the seller doesn't know, get it checked before you buy. I'm telling you this because I'd much rather help you avoid a nasty surprise than see you paying to put it right afterwards.

I hope this article has helped you! If it has, I'd love you to share it with a friend who drives an automatic or is looking to buy one. My mission is simple: when I know something useful, I want more people to know it too. Because the better you understand your car, the harder it is for someone to pull the wool over your eyes, and the less money you'll waste on repairs you never needed in the first place.

Frequently asked questions

What's the difference between DSG and S tronic?

Both are dual-clutch automatic gearboxes. DSG is Volkswagen's name, while S tronic is Audi's. In some models they belong to the same gearbox family, but Audi models with longitudinal engines use a different design.

Is Tiptronic an automatic gearbox?

Yes. Tiptronic is a traditional automatic gearbox with a torque converter. It changes gears automatically, but you can also select the gears manually if you want to.

Which automatic gearbox is the most reliable?

You can't judge reliability just from the name DSG, S tronic or Tiptronic. What matters is the exact gearbox model, how it's been looked after and whether it's been serviced on time.

Does a gearbox need adaptation after an oil change?

Yes. At Das Auto Service, we carry out an adaptation procedure after every automatic gearbox service. For us, it's an essential part of doing the job properly.
