Well I have a 2.0 tdi dsg Golf estate and I am absolutely delighted with it. It is very responsive, seems to learn your driving style too.

My friend bought an Ateca dsg and his son has a well used dsg gti Golf.

We bought it S/H with full service history from a VW dealer in Germany with 50k km on theclock. It had had the dsg oil and filter changed at 32k miles so I have kept that up ever since. Now at 180 k km.

Last time I was in uk, taxi to airport was a high mileage dsg Skoda Superb. Guy had his dsg serviced regularly. He did say that the flywheel needed work and demonstrated why he knew . Something to do with low running.

So it is a go for it from me. Skoda estate has a bigger boot than the golf too last time I checked. Our golf has a fancy diff control not fitted ( then) on the seat and skoda equivalents.

I'm going off the idea, glad I asked. Question is, why are more modern boxes not as good as torque converter ones  :-\


I hope the current VW DSG boxes are better than the first ones. You know, the ones that had a nasty habit of selecting two gears at once, which cost about £3k to fix. Their biggest selling point seems to be how fast they can change gear, which is utterly irrelevant in real use.

.. and I'd wager the ZF8 in my Jag is just as quick at shifting and it's certainly more refined. I'd only ever go for a conventional slushbox. Dual clutch types are trying to solve a problem that doesn't exist.

It would take a bullet to the head to buy a recent/current VAG product.

It would take two to buy one with a DSG box.

Have the ZF 8 Speed in my 530D and agree, it's an excellent box.

A little while ago we were looking for an automatic estate for Mrs VXL, we really liked the Passat's but at the age and mileage we were looking at I didn't fancy anything with a DSG going on the general opinion of them. I guess at lower mileages with a service history on the box then it's a different story.

they're supposed to be a little more economical compared to a slipping slush box

Agreed .... I can never see the point in a couple of nanosecond gear change either  :-\

DSG is a massive compromise as an auto, its trying to pretend to be an auto by using two clutches (bloody expensive ones to) and effectively an odd and an even gearbox with servos to do the shifting. It was only really considered as Auto's of the time were lossy but, this has long since been addressed with Autos supporting lock up in most and many all gears, and you can't beat a torque converter for coupling to an engine. They can give one fast upshift (as the box sits with the next gear up engaged on the parralel box), a second shift will not be quick and downshifts are also laggy as the second box has to make the shift and then action the change.

So you end up with a very heavy and complex gearbox, with twin clutches, a much more frequent service need (and sadly many dont bother!), and one that has slow downchanges and double gear shift actions.

The DSG is not actually new to VAG, its been around for some time and it was really Borg Warner that pushed to get it to the main stream (contary to popular belief) as they were lagging on the classic auto box front (difficult to compete with ZF and Aisin)

Would I have one, well if your set on a small/medium VAG products (they don't use it in the bigger more capable models e.g. RS6 etc) with an auto then you have little choice, would I want one, no, as conventional Autos are much better and require much less care.........they are also cheaper to sort when they go wrong.

Not since autos supported lockup in all/most gears  :y

Ever driven a Sprinter with the automated manual?
No? I envy you, and that's not something I ever expected to write 8)
Imagine a transmission where every joint between the crankshaft and the ground is poorly made of squashy rubber.
Then let the person who programmed the original Smart gearbox loose on it.
