Mine does it

60 km/h or just over will go into 7th if there is any load yes the engine does "labour" if you are on the gas a little

If it's happening I just ease off a bit to about 59km/h and it will change back to 6th

if it's flat road it goes fine though or at about 65km/h

This sounds exactly like what mine does. Rather than drop down to 59kms every time, I just shift down manually, but it's a pain in the arse. I'll be driving along in 6th just under 60 with the revs already very low and then BAM, I hit 60, the revs drop through the floor and car starts vibrating.

I took my car in for it's service late last week. In my limited time driving it since, it is still exactly the same regarding this issue, though they told me they fixed it with an ECU update. Surely, they were telling the truth.[emoji6] They also told me the ECU update fixed the acceleration lag and the roll back. The acceleration lag did feel better in my short time with the car, but this was always an inconsistant issue, so I'll wait and see before making a judgement. The roll back, I don't know yet.

Thought I'd give an update. The car is the same as before the ECU update. Acceleration may or may not be better. It's hard to tell. Vibration is exactly the same. What really annoys me is that the same dealer told me before that the vibration was normal and now they tell me they fixed it with the ECU, which was a lie anyway.

I had a Fabia as my loan car. Is this the same 1.2 as the Yeti? It was a 7 speed DSG and had no vibration whatsoever and I tried my hardest to get it to do it too. It went really well. It changed up at exactly the same speeds as the Yeti, but ran fine.

Could the vibration in the Yeti come from the engine being underpowered? If the Yeti is a heavier car, wouldn't you need to stay in lower gear a little longer than the Fabia? They are mapped exactly the same as far as I can tell. This doesn't make sense. If I drive in manual shift mode I get no vibration, so the DSG and the 1.2 are not a matchup problem, but the way it's programmed is.

I'm no motoring expert, but am I making some sort of sense?

All this bearing in mind that others here claim to have no vibration, but that's another issue.

It seems like the dealer is trying to wear you down and hoping you'll give up.

Has he got a 'reputation' - good or bad?.

I don't know what their rep is like, but they are big and well known. They sell multiple Asian and Euro brands. I've been sent a survey about the service I've received, so I'll soon find out if they actually care.

With their current approach, they'll have you in MazHondai before long and still making money from you.

I have had a few cars over the years with vibration issues at a specific speed which you refer to as the main issue and not a specific gear and they have all been tyre/wheel related and nothing more sinister.

Only a thought.

40mph is a sweet spot for wheel balance and tyre egging to make its self known. Does it go away when you get up to 50-60 mph? Swapping front wheels with rear is a simple way to check diy. I've seen a duff cv joint cause similar symptoms aswell.

You could really do with taking one of their cars for a spin and seeing if that is the same or not.

The wheels were apparantly switched during the service, but I doubt it's the wheels as when I shift down manually, but keep the same speed, the vibration goes away. The Fabia I drove as my loan car did not have the same problem, despite also being a 1.2l, 7 speed dsg. The auto gear changes were at the same speeds as the Yeti, but didn't cause vibration. If I drive the car in manual, I don't get vibration. I think the auto is just in the wrong gear at these speeds.

What's the difference the tachometer is reading in manual without vibration and auto with the vibration?

Same engine and gearbox and whilst it was good that you found that it can work well you obviously can't do a direct comparison as there are just too many differences, notably the weight. I understand why you think the gear ratio may be wrong because of this but there may be other factors in a Yeti (shape and component layout etc.) which may be more liable to cause the issues you are having i.e. the Yeti may cause more resonance at certain speeds/loads. 

 

But others have reported that they don't have a problem which does point to yours having one.

 

As I said, the only true comparison is to try another Yeti as close to your spec. Until you do it will only continue your conjecture and you will make little progress in reaching a conclusion. If you find another example is fine then that will strengthen your arm with the dealer.

Yes, I mentioned about the weight probably being a factor in a previous post. It doesn't make sense to me that the gear mapping would be the same for the same engine and gearbox in a heavier vehicle, but it appears they are. I have to keep the revs above 1400 in the Yeti for it not to vibrate. In the Fabia it could rev below that and be fine. The dsg is supposed to be so intelligent and is advertised by Skoda as always being in the right gear, but it doesn't change gear when it's labouring the engine unless I really put my foot down, thus increasing my speed. Surely a car should be able to maintain a constant and very common speed with labouring. It doesn't seem very intelligent to me.

I will try another Yeti when I get the chance, but whether it does it or not, it needs to be fixed.

See if you can organise a test drive of a 1.2L (and also perhaps a 1.4L too) Yeti through a local dealer?

Unfortunately the pursuit of better mpg may well be at the expense of other criteria e.g. drivability and mechanical sympathy.

 

Don't know what the handbook says but it used to advise against lugging engines as well as revving the nuts off them. The way your car is performing (correct or not) is against that advice and good driving practice.

 

When I had my Passat DSG that would sometimes move into too higher gear for my liking but at least it was a 2.0 litre, 140BHP diesel and so it could cope with it better.

We live 100M from a corner and the 308 driven gently is in 3rd & 1000rpm before we get to it.

The programming is ALL about CO2 emissions/economy unless you select S or manual mode.
