My theory is that a certain amount of oil has accumulated in the intercooler radiator due to excessive blow-by and breather pipe inefficiency.
At a certain point this oil was suddenly and entirely entered in the intake duct causing the puff of smoke...

This could not happen at every acceleration, but just when pipes or radiator accumulate a certain amount of oil...

This is the typical case of "the dog chasing its tail": the more blow-by happens, the more oil will be entered in the intake, the more piston rings will be inefficient because of the oil burned, causing more blow-by.........


EDIT: of course if smoke it's not due to oil burning, my theory is not applicable...

The smoke is black my friend, not grey / white / blue. It is just a hang-up in the dsg's brain which VAG won't fix ala APR's DSG tune because while overseas they will warrant this software change, here they don't like to admit the f**ked something (like the entire car) up. Had it happen to me this morning pulling out around a garbage truck, thought I put enough throttle in (to be fair, it's the first time I have driven in D for about 3 months) for the car to stay in first but noooooo, the idoit that wrote the software program made my dsg go into 2nd at 5kph while I was requesting 1/2-3/4 throttle!!!
Sometimes this bloody car makes me soooooo mad!

Just let me know when you want that C4. Have you got the ski masks ready.
Ahhh ****. Blown our cover.
Hahahaha

[kawabanga]

I use to get the same issue with an old Alfasud, just before I was forced to get an engine rebuild.

Really Alfasud was exported to Australia...? Can't beleive it...!

I completely agree...!!!

[nomadx38]

Haha Gavs you make me laugh. Who do you normally drive your car in?

I'm usually driving in D and a will say it does some weird things if you don't know how to drive with it. The first rule I find is if you want to progressively take off put your foot down and keep it there (or give it more gas).

As soon as you lift off the throttle even a fraction the gearbox sees it as that you are happy with your speed. It will then quickly downshift to the lowest gear, disengage the turbo (open the wastegate) and give you very little throttle response for max fuel economy, which leaves you mashing the pedal for it to kick up a gear as it spools the turbo again.

This differs from S or M where I find it will keep the turbo wastegate permanently closed for max boost and min lag.

Just my 2 cents

[yokom46]

imo the gearbox is more suited for manual use. It seems (at least from my perspective) that they may have designed the box for manual first and auto second.

Dad just bought an Audi A3 S-line with the 2ltr tfsi engine in it with DSG and complains about the lazyness of DSG in D around town.
I can't for the life of me figure out what is so difficult about using the gearbox in manual mode all of the time.. lol - I do.

[Eaglehawk]

I agree with the manual or S overriding being a solution to all the problems I've observed. My driving actually involves a bit more gear sticking shifting than normal. I actually use Neutral when going down hills. (This behaviour drives my wife nuts) Of course, VW/Audi now implement this as "coast mode" or something. I've been driving like this since 1997

I have this vague memory of coasting for 1.5km along Dandenong Road in Malvern once...in peak hour...

Why would you do that? You use less fuel in gear when coasting. And if you need to accelerate to avoid something?

[Melon Head]

Yeah mate. I owned 2 Alfasuds and an Alfa 33. Raced both of the Alfasuds. One of my favourite cars. Bloody fun. Very crappy gearbox though. Synchros would wear out very fast, a bit like changing gears in a truck. Hahaha.
My mate raced at Targa Tasmania in one, and the very first year he entered that race, he won it (in the cars division).

I find the slight engine braking even in D still slows down the car more than putting it into neutral. Yes, the engine isn't fuel when you're in D (well, according to the instant consumption), but the higher speed I keep seems to make up for it. I always thought it did save fuel, so why are car companies now doing it? *shrug*

Ok that's fine I was just wondering The coast mode on the new Passat and Tiguan is really good, keeps the engine nice and quiet until you brake or accelerate then it shoves it back into gear without even being able to feel it.

[Guest001]

Can I ask why you would buy an auto and then drive it in manual.

Why not buy the manual and save some money.

Coasting in neutral is fraught with danger as well especially downhill.

Try the hills into Adelaide and see whats left at the bottom.

Yes you have been doing it for years so it must be OK.

How many times have I heard that.

Aside from the GTI only coming in "auto" I personally have found the D mode of the DSG an annoyance so I drive most of the time (80% would be a safe guess) in manual. People forget that it is a manual gearbox that is controlled by a computer.

[Zakarados]

This probably isn't a problem but more of a safety feature, but I have noticed something very annoying.

When driving in manual, and driving HARD, in first when getting close to redline the gearbox will automatically change up to second, then I attempt the up shift thinking I am still in first, leaving me in third gear and with no power/torque.

I know this is probably to protect the engine, but isn't that what the rev limiter is for?

Yeah, the car will always up shift at redline and won't downshift if it doesn't like the amount of revs it will drop to when you try and downshift at a certain rev range. It also won't up shift if you request it below 1800rpm in the first 4 gears.

For ~$900 you can have this changed however.

Thanks for clarifying... silly though... so best to do sprints from dig in Sports mode?
