I don't believe there is any adaptation that the ECU makes that can give better mpg, LuisM seems to obtain similar as well.

In fact my 48-50 mpg estimate was not based on a pure highway drive. It was based on my commuting, which is mostly highway but includes some stretches of town. On a highway alone, without traffic, I probably get some 55 mpg.
I've put mine in Auto like yours @cuke2u - I prefer that the steering feels more 'real' than being in Comfort, also the throttle seems to have that small area when your just trying to maintain your speed where it won't throttle it too much, making it more smoother. In comfort and definitely dynamic the car seems very lively trying to keep it at 30mph, it's a lot nicer now - so i'll keep the drive modes for fun and keep it in auto!
The odd random drive I do, sometimes I go on a little country trip to work (I do live next to work so I normally bike, but sometimes I take the car) it's about 10 miles of country rounds and I get around 43mpg. As I said, best so far was coming back from cromer not driving like a saint and doing 50mpg. I drove like a saint on the way up in efficiency mode and had the fuel saver on the DIS and I got 46mpg
I'm HOPEFULLY if my girlfriend gets her holiday signed off going back to cromer for July. Hopefully Cornwall in August which is a 500 mile motorway drive for me so i'll be sure to post what MPG I get. I don't think what helps me though is my car has a lot less miles. Then again, it's definitely run in a little because I took it round a track a month ago which helped the O rings bed in
haha. Had less oil consumption since.

All I can say is that if I drive like a granny then mpg over 60 can easily be achieved. I use a test I have put together to compare different car's fuel consumption, its not real world but I know the route and I drive the cars exactly the same way. My previous car, a remapped mk3 1.6 ecoboost focus, used to get 59mpg on that route, but my audi managed 87.
If only I could drive my car at that all of the time, as I stated, it isn't really reflective of real world motoring as it's just a test I've devised. I think my figures of 65mpg driven with economy in mind are far easier to replicate.
I've garaged my car for the week since it should be nice weather so I can bike to work (thats the plan anyway...)
I had a drive last night after I dropped my girlfriend home and couldn't stop driving it. I thought I'll head home now but in the end got on the M1 went to MK and back just to see what it was like. Had no music playing, got to say after this update I notice the supercharger whine a lot more, especially if I'm doing 60 then put my foot down and get to 70 you can just hear it slightly whine/whoosh - what a great sound haha. I got on the motorway and drove sensibly down to MK, I had it in Auto which is a much nicer mode than comfort, the thottle response is less so it's easier to maintain your speed + doesn't feel like the car is always being too excited to accelerate - until you put your foot further down and it still goes - also the steering feels a lot more real and not fake like in dynamic, it's way too heavy and I feel I just cannot predict the car in that mode, just feels like you don't have power steering... I put it in Dynamic actually after Auto - which used to jolt quite harsh EVERY time out of 2 cyl at 70 when putting my foot down to get into the fast lane because of some cars going a bit fast... but now I can say it's a lot better - it still does jolt the odd time, but a lot less harsh and almost to the point I don't mind it, especially because it's only the odd time compared to every time. I still believe they can improve it though, and probably will. As for the vibrations I noticed them once on the A45 where it's 60mph for Brackmills section... they've resurfaced it a bit there so I noticed it then, it feels like your driving over lumpy ground which sometimes you are, I get that and look at my DIS and I'm not in 2 cyl, it's just the road. Obviously it's new tarmac + as soon as it came out 2 cyl for a small incline it stopped. I really didn't mind it though, not very noticeable.
Still cannot see great MPG figures, I drove around the country for a bit sensibly not putting my foot down and got 43mpg. Got on the motorway did 70 - 80 and got 41.9 mpg. Still not very very impressed yet, but not complaining either. I have 3100 miles, so plenty of time yet to loosen up...

Put mine into Dynamic mode on the way home from work yesterday and by the morning I'd forgotten it was in it, yes there is a better throttle response and low down grunt, however no jerking. So either I am am smoother driver, hence the better mpg, or something is up with your car. Anyway I switched it back to auto as I find the lighter steering easier to drive around town.
It is strange you can get those mega mpg figures and no jolts or vibrations. Yours just be a Jem, that courtesy car 15 plate did the same as mine, it wasn't perfect.
Strange, they don't make 2 cars the same

I seems to though, always be able to get good mpg out of my cars, must be just the smooth driving I guess. I wonder if it would be the same if I drove yours?

The software update was reported by user @dkpeter on this same thread, specifically here (and also in some of the preceding posts). We really are indebted to this guy!
It could hardly have been @cuke2u, considering he deemed the vibration issue to be something that "doesn't really exist, more perceived that factual", and thought we were "deliberately creating a perceived issue"

There we were all getting only nicely, considering the reported issues were a minority of two or three out of the many who have reported no issues and you yourself have stated that perhaps what you were perceiving might in fact have been cured by a reset of the ecu. There really isn't much proof of anything and in fact it could have simply been a badly calibrated sensor....

What I said was, I had some fear that the improvement might be just temporary, due to an ECU resetting and eventually going back to "normal". But luckily it seems that was not the case.
Here are some facts. Audi has issued several versions of an update for this. The update specifically deals with "vibration and jolting issues for the 1.4 TFSI CoD engine" (I saw that description on the dealer's computer -- only in Spanish, of course). Three of us have reported a significant improvement after the update.
So what do you need further proof of, exactly?
I'm afraid he isn't joking, but the figures he continually pulls out of his backside are a joke. What he does is he looks at his economy reading when he's driving along at 60mph for a little while and then claims that's the fuel economy he's getting. He once took a picture of a trip reading, which wasn't even of an Audi but a Ford he claimed he once owned and no longer had, and claimed similar figures because of his ultra efficient driving. The trip gave him away though because he'd done it over a ridiculously small journey so he probably rolled it down a hill for the purpose.
I can easily claim that I get 80 to 90 mpg on a two or three mile stretch at 60mph on my morning journey, but I would never shout that from the rooftops as what I'm getting from my diesel car because, as we all know, that's idiotic. You have to look at what you get from a good half or full tank of fuel with a complete range of driving and for me that's late 40s edging into early 50s mpg. Nowhere near official figures, but, correct.
Don't try and engage him further on this because you aren't going to learn anything, you'll just end up getting the impression you can get economy figures you can never get and frankly you're just massaging the ego of a bizarre character.
Low 40s on a modern petrol car is about right. In summer it might go up slightly, and obviously go down in winter into the 30s, but that's about right.

I concur. You should average over a full tank or so. In that case I get about 40 mpg. And I'm really happy with that figure. I think it's great for a 140-BH petrol engine
If there are updates related to these types of issues and they'e being applied when the car is serviced then Audi and VAG have acknowledged there is a problem. That's the end of the debate right there.
Personally, although I drove the 1.4 engine and it was very nice I have known people get stung by direct injection engine problems on VAGs and Mercedes in the past. Over about 60,000 miles their pistons tended to get worn into cones. However, unlike the previous incarnation of the 1.4 engine a few years ago it is nice to see VAG identifying and proactively doing something about potential problems so that, hopefully, most people will never notice.
You do make me laugh with your totally incorrect assumptions, without this thread degenerating into another mpg argument perhaps before you post you should ask for more information, that way you aren't taking out of your backside and making an idiot of yourself.
I have never ran my car showing instant mpg, only average which I look at the end of my journey.

Although, just to throw the spanner in the works, I have an earlier car than some of the few that have a posted up this 'issue', thus, if what is said is true, then my car should have had this 'vibration', which it has never had, not once, not never and the first time it was service was in March this year, after this thread began. From what the other owners have said that haven't got this vibration that theory can be contradicted by actual experiences...

Your reasoning is wrong. What happens is, some units have the issue, others don't.
In the Spanish forum, for example, people keep complaining about some screeching in the rear brakes. I've never had that noise in my car. Not once, not ever. So, are they lying? Or imagining things "more perceived than factual"? No, they are not! It's just that some have the issue, others don't. That's it. Is it so hard for you to understand?. Not all units of the same car model develop the same problems
Can't see the comparison really, aside from when one person 'suggests' they have a problem everyone else thinks they have because they look for something that isn't actually there and then you get a forum inbalance. Placebo effect...

"Something that isn't actually there"?
As I've said several times on this thread: speak for yourself, and your car. The vibrations may "not actually be there" in your car. But they definitely are there in my car (fortunately, much weaker now after the update). See the difference? You car, my car. You can't have an opinion about my car when you haven't driven it. So don't tell me what my car does or doesn't do.

Right, not really the topic from the OP, but I have only seen the 2-COD mode come up on my display a few times when i bought the car over 2 weeks ago. Since then, I dont know what way to drive to see it come back on. Any suggestions on what mode/display is needed to see it appear?

Select normal view (leftmost tab) on the FIS.
Press left thumb button and select uppermost option. It's the one that shows time in the upper part, miles in the lower part, and you can select (with the thumb wheel) what is shown in the middle part.
Select instantaneous or average mpg in the middle part (using the left thumb wheel).
(These indications apply to my Spanish version of the car. I think it will be the same for other countries).

You should see it in this view:

If I remember correctly, when in 2-cylinder mode the mile or km indication disappears to show a "2 cylinder mode" indication

Comes up a lot now, its just the way that I had the display. Strange that it doesn't appear in all modes, but least I know its work! Cheers
I'm just about to make a new thread to report that 1.4 COD doesn't like premium fuel at all, because I drove to Cromer the last week and it didn't stop vibrating and jolting, especially around cromer in the small one way streets where I leave it in 2nd gear because your bumper to bumper and all it did was vibrate.
I've since then put normal fuel back in it, and it runs like a dream. I am impressed, the update has made a big difference.
Still, I don't think i'll buy another cylinder on demand car ever again to be honest.
I have noticed a vibration myself now that I've tested mine a bit. It's not bad or putting me off, but there is definitely a vibration or a sort of fast purring sound when I'm slowly accelerating away from a low speed. Happens on occasion.
To be honest I don't think my car ever gets into 2-cyl mode...I'd love to see some stats pulled from the ECU on "Time spent in 2-Cyl Mode". I'm thinking 20 minutes out of 24+ hours of driving time.

They've done some tweaking so it doesn't come in so much. Worst for me was when I was doing 40mph, it would come in and out in and out all the time and vibrate really noticeably. They've upped the revs that it comes in at now, so when I'm doing 40mph in 6th it won't come in anymore, which is much better.
30mph used to be a pain for jolts, not so much vibrations but both have been improved, mine rarely jolts now - unless as I found, if I run it on V-Power it doesn't like it. Must be something to do with timing or just the fact it's higher octane fuel on a very complicated engine. No idea why, but I promise it was like it was before the update, and as soon as I put normal 95RON petrol in it drives like a normal car again (the odd thing I can notice but it's nothing too bothering). Very strange
I'm just wondering, after 3 years wether I will keep the car, just not so sure if it goes wrong, it'd be ****** complicated and expensive.
I'm probably going to go for a 1.8 TFSI or if I can stretch I would want an S3. All depends at the time, but I'll see.
Just not 100% impressed, to me 27k for a car that jolts/vibrates a bit cuz in my mind the 2 cyl mode ruins the car, however this engine hasn't been out long, and this update did make a big difference so there might be yet another update which just gets better and better.
OH - and a MPG update. I did 49mpg going to cromer - 136 mile drive and I didn't drive like a saint one bit, had it in comfort, I overtook some slow go-urs (yes I was doing the speed limit lol) then got overtook by an S3 which didn't want to do the speed limit!
I'm impressed the car did 49 when I was driving normally, not nursing it at all. I think if I did, maybe I could get 55mpg..
It's a great engine and has a good bit of poke, except for my experiences with poor throttle response - http://www.audi-sport.net/xf/threads/slow-throttle-response.243246/ - which really spoils it for me. It's supposed to have 150bhp but with that throttle it feels underpowered. Getting into other cars with normal throttles are a joy! Taking it to Audi hopefully tomorrow morning to see the "master technician" about it.
When you get going and drop a few gears to accelerate it's also fast. Engine noise is a bit strained at high revs so I try to avoid that - low down it has a bit of growl which is good. Funnily enough it sounds a lot like a 2003 Ford Focus when accelerating from 0 to 30mph - not a bad thing, just an observation.
On topic though - yesterday I didn't notice any vibrations and I was purposely trying to get it into 2-cyl mode. I don't really feel the COD aspect of it has helped fuel economy, or anything really...but what it has done is reduce the CO2 tax I pay on it and give me more power at the same time...win win!

As far as know the 'throttle' on my a3 is no different to the one that was in my focus, all 'fly by wire', however the a3 is far more responsive than the focus was, even though the focus had a remap..
Hence why I think mine needs adjusting. I'm hoping it is an issue - at least I know it's not normal. The worst thing they can say is it's a characteristic of S-Tronic or the A3 in general.
