Guys
What is the difference between Automatic, Tiptronic and S-tronic please, and which is the best (on a Q5 petrol)?

Automatic means any non-manual box.
Tiptronic is a conventional 'slush-box' torque-converter automatic, but with steering-wheel paddles to override.
S-Tronic is a dual-clutch DSG system. Electronics allow it to operate in an automatic fashion. Think of it as a computer-controlled manual gearbox.

Which is best? Manual! But if you must have automatic, then S-Tronic. (More efficient so better MPG, faster changes)

Thanks! So if a Q5 is described as "Automatic", the it's missing the detail of whether it's Tip or S-tronic?

Yes, but I think S-Tronic petrol Q5's are pretty rare. You can only spec S-Tronic in diesel Q5's now.

Can't comment on the Q5 specifically, but as the owner of an S-Tronic equipped S4 (fair enough an '09 version), the S-Tronic aren't known to be bombproof. They are very complex pieces of kit with repair / parts prices to match.

Take my situation; a slight knock / jump when coming to a halt going from D2 to D1.

There are three major component groups to consider; the clutch packs, the gearbox and the mechatronic unit. Each one of those can have an 'issue' which results in the symptoms I have. To replace the clutch packs is probably north of £1,000, the mechatronic replacement I was quoted at £3,500 from a local indie and a gearbox was going to be north of £8,000.

I have a warranty that covers the first £2k of these, but the problem is working out which bit is bust. In the end I went for a gearbox re-adaption which involves wiping all the settings in the gearbox and re-training it (bite points, gearchange speeds etc etc). That seems to have solved the problem for now. But I'm well aware that it could just give up.

The benefits are that I get 'auto' driving in the city, can play with the paddles on the A- / B-roads. The other thing is that my warranty company couldn't quite make up their mind what category the gearbox fell into as they only state manual, automatic or CVT. They decided it was an automatic, which is good as it then covers the clutches and mechatronic units.

Late S-Tronics (~11 on) give virtually zero issues.

2.0T Q5 uses the 8 speed ZF torque convertor from 2011 which is also strong.

They're both nice boxes.

So just my vintage that's made of chocolate then... oh well.

It is the strangest thing; I've had some high mileage, early S4s through where the box has been good as gold. Even a couple that have missed oil changes and given zero grief.

Then you get the 30k mile car that's had the oil done twice and it goes pop for no apparent reason.

We take a view that if the oil has been done on time and they drive properly then they're probably OK.

Always S4s and Q5s that play up too; same box in an A4/5 seen no issues at all.

Sure about what? Box yes, exact switch date no.

8 speed "Proper" Auto with a Torque Converter. (i.e. not a S Tronic )

On a 2.0T Q5?

On a Q7. Yes I'd agree. But a Q5?
