Poor fuel economy 2017 1.2 TSi DSG

[gman88667733]

Just a note to add, it seems to depend a lot on the road surface I drive on, driving home on a fairly flat tarmac road that is well worn, it didn't seem to vibrate at all. It is only on roads around town that I hear it. Weird?

One option is for you to drive the car on your normal route, or the route you notice the issues with, and have a passenger record it; showing the DSG changing up/down when you think it is unnecessary, you comment every time you feel the vibration, (in case it is not obvious on the recorded video).  Arrange for your local dealer to drive your vehicle over your route, whilst you record it; compare footage.

 

Drive a similar vehicle to yours, again record it, and compare footage to yours.  Take it from there.

I shouldve taken advantage of being in the other Yeti whilst I had the chance!!

Something clearly not right imho.

 

Even when new I got 34/35 mpg on my 1.2 TSI DSG yeti, and by 10,000 miles was in the 38-40 range.  I average out at about 39-40, with mainly 7 mile trips into town. Long motorway trips (400 mile each way) at 70mph I am getting 41.  measure by fuel tank full to fuel tank full using gps mileage or from the speedo.

 

Gearchanges to me seem to take place as I would expect. Doesn't change down until it needs to. Takes 70mph uphill m6 at shap in 5th.

Mpg is hard for me to judge as my trip home from work is all uphill, going to work I get about 52mpg... But it varies so much.

[gman88667733]

Just filled up. I managed to get 45 litres in it and I had travelled 315 miles. Which is 31.82mpg. I think I could have gotten more out of it if I had done longer journeys. Bearing in mind that half of my journeys are all uphill in probably 3rd gear.

So I guess that isn't quite so bad.

Just checked last three fill-to-fill fuel consumption. They are 48.54 MPG, 47.86 MPG & 47.87 MPG. Driving a mix of motorways (mostly motorway for the 48.54 reading driving at 70 MPH.). Other readings a mix of rural urban and dual carriageway roads with journeys between 6 miles and 30 miles - mostly 6-7 miles one way with 40 minute rest then 6-7 miles return.

Checked change up speeds, all on level with light throttle, changes from 4th to 5th at 30'ish then 5th to 6th at 36'ish and to 7th at 40'ish. Slight pressure on accelerator then change speeds are increased as you would expect. No vibration or labouring at all. Doesn't the DSG gearbox "learn" your driving style and adapt changes to suit?

Really the only gear change that causes issues is 5 to 6. It changes at 32 or so and until the car is up to 35 mph, it sounds strained. I don't think vibrations are the right way to describe it actually, the engine note goes much lower and sounds like a diesel until the car speeds up a few mph. I'm going to try a VCDS DSG reset and see if that helps at all. When I am harder on the throttle, it changes up much later. However, i tend to drive on basically no throttle 

[Expatman]

It sounds like your Yeti is changing up to 6th when mine is changing up to 5th! Just tried to force a change (feathering throttle) at 32'ish from 5th to 6th BUT it just wouldn't do it - simply stayed in 5th until I got to 36'ish.

I would talk to your dealer as it sounds like something needs re-setting. I am not sure if Skoda have modified the DSG box since  2014 which could explain the difference although  I don't remember my previous 2012 1.2 DSG labouring.

The other yeti I briefly tried changed up to 5th at 28-30mph. It was the same age/mileage as mine. I'm going to get a local specialist to perform a VCDS DSG reset I think, so I'll see if that works. The dealership already told me that it is normal for it to change up that early. Do you get what I mean when it sounded like a diesel engine note at 32mph in 6th?

My vehicle won’t select 6th until 81 kph but hang on to it decelerating until 70 kph.......50 kph is rediculous.

That does not sound right either. Is yours the 7sp box? Pretty much every 7sp DSG box I've seen changes up into top gear by 45mph at the very latest on light throttle. 

[bigjohn]

Is the poor mpg of the 1.2 in the Yeti just a DSG issue or are the manual versions as bad?

 

I ask as I had been wondering about one of the last/latest 1.2 versions (EA211) but would be horrified with 30mpg - My Superb barge 1.4tsi is averaging 46mpg

That is disturbingly fast (81 kph = 50 mph) to change up to 6th - whatever speed does it shift to 7th gear?

Mines a Citroen with selection points similar to my old 6DSG Yeti.

Remember that my journeys are unusual compared to most. I live in a very, very hilly area! On a run I got closer to 40.

DSG is completely different to that though, they shift entirely for economy

This is a most confusing thread. We seem to have some people who struggle to get much into the 30's yet many others get well over 40 mpg. Look at my previous posts to see that I have got as much as 48 MPG and over 6,500 miles I am averaging  a brim-full-to brim-full 44.4 MPG. MPG is improving as mileage increases which is exactly what happened with my previous 2012 1.2 DSG. A Yeti is nowhere near as aerodynamic as a Superb so would expect it to use more fuel.

Apparently ecu controlled transmissions ‘learn’ your driving style and adapt to it.    If that’s the case it needs to be taught a lesson surely.

One half of my commute is on average uphill and the other half downhill. On a run I'm closer to 50mpg (sometimes over)   - This is a Superb not a Yeti so aerodynamics probably better but it's a heavy beast

If your typical commute is only 6-7 miles what would you expect.........it’s effectively all cold running.

[gman88667733]

I know. Can someone confirm what I mean about the engine note dropping a lot when it changes up early? I'm sure that is what I'm hearing. 

I hope a DSG reset will fix this, or at least help...

That's why I started this thread - I'd read good reports of the fuel economy on the 1.2 DSG and would have hoped for 40mpg. Previously she had a Golf MKVI with the 2.0 TDi DSG, which had the emissions fix done and then failed catastrophically 2 weeks later -fortunately VW accepted liability and replaced the Turbo, EGR and DPF - however she'd lost all faith in diesel.

I thought the EA211 engine was supposed to warm up very quickly?

 

The mpg is poor for the first couple of miles with my EA111 1.4 but quickly improves after that. It does get badly hit on the uphill part of my commute but the average improves after that but it can vary between 43 and 53mpg average on my journey to work depending on traffic.

 

My previous Superb I pd seemed to just do 50mpg whatever

Okay most mornings I drive to get the paper, 3.5 miles there and 3.5 miles back. Since I got the car new at the end of March 2017 the temp gauge has indicated 90 (dead centre) by the time I get to the paper shop and stop/start is working. Three minute stop for papers and then drive back and almost invariably the maxi dot is showing about 50MPG "average" by the time I get back. Okay the drive is flat and  on country roads and I would rarely get to over 50MPH but it is hardly a long distance drive!

In comparison the temp gauge on my previous 2012 DSG Yeti would have hardly moved off cold by the time I got to the paper shop and barely have got to 90 by the time I got home. Maxidot was just over 40 at best.

I am at a loss to understand why some drivers are getting low 30's?
