Just returned from sharing the driving around France in brother-in-law's Yeti 1.2 SEL with DSG gearbox. I was impressed with the seamless gear changes and always in the right gear for every situation. I did experience once or twice a disconcerting operation of the DSG box. When starting off fully loaded on uphill gradients more throttle is required than normal to compensate for the extra weight. The drive then engages trying to wheel spin. This is more noticeable on a loose gravel road.  Is this an oddity of the DSG system?

Wheelspin is perfectly normal, nothing to do with the DSG.

 

High load, uphill on gravel will certainly exacerbate it.

Same would happen with a Yeti 1.2 TSI manual would it not, oddity of a FWD Yeti and small turbo engine.

My 2.0 110 manual Yeti did it.

 

My 1.4 DSG Superb does it

 

Actually, all my cars have done it

Don't forget your BiL's Yeti is heavier than your Roomster - roughly equivalent to having an extra passenger on board.

 

The tendency to wheelspin can be minimised by waiting for the drive to engage before using the accelerator.  The drive engages approx. one second after releasing the footbrake.  This one-second wait becomes second nature in a very short time.

 

I have owned two Roomsters - one manual and one DSG.  My Yeti is DSG and a joy to drive.  I would not want to go back to a manual.

Wheel spin has been a very minor irritation for me in both my DSG Yetis the first one being a 2.0 litre 140TDI. I don't know if I'm right or wrong but in my mind I put it down to the 'fly by wire' throttle.

Yes, I have a manual gearbox but I engage the clutch and give more throttle after the clutch bites so no wheel spin. The DSG box seems to bite at more revs and snatches to spin the wheels. I need more practice!

150ps or more & Haldex was for that very reason.

Heavy car, small capacity turbo and a DQ200 7 Speed Twin Dry Clutch results in what you have experienced.

Not so much heavy car as light engine, 2WD, and when pointing up-hill, there is weight transfer to the rear axle further decreasing traction at the front wheels.

In our 1.2 TSI DSG Yeti, it was very easy to spin the wheels.  In our 170 TDI DSG Yeti, almost never. Drive to 4 wheels plus traction control does the business.

Exactly - my 110 2WD Yeti would spin easily, but my 170 4WD never did, even when remapped,

Can I change my position on this a little.

 

I've been paying more attention to the DSG in the Superb over the last few days and it's noticeable that, especially when combined with the electric/automatic handbrake, the car does set off with a bit of a jerk.

 

So yes, while uphill/gravel/2WD/heavy load will accentuate a car's tendency to wheelspin, the DSG will indeed make things worse.

 

Now I'm hoping that we don't have a lot of snow this year :-(

Do you not have 'autohold' so that the e-brake is not needed once you set off unless you use the parking brake?   People drive with a DSG all around the world, so that included in snow for millions of drivers.

I do, but as BillyJim suggests here :- 

 autohold tends to let off abruptly. As you pull away the motion isn't particularly smooth.

 

I have to admit that I've got into the habit in traffic of just nudging the accelerator (which releases the brake) then accelerating away as that's smoother than simply pressing the accelerator from a stop, Or I do it all on the DCC which is nice and smooth too.

I suggest if working correctly 'Autohold' does not let off abruptly, but then that is my experience of driving a lot of different DSG's.

Driving petrols and diesels and in different terrains.

DSG's just with a Mechanical parking brake and no Stop / Start but Hill Hold Assist, then stop / start, then E-brakes, then E-brakes with Autohold.

Evolutions, and if there are issues, sometimes that is a user issue, sometimes actual faults, but no point saying all do something when obviously all do not behave the same.

Apparently some say something when they get cars that later they might say or think something differently later.

It had a normal manual handbrake. I used the handbrake as I did not know if the car may run back.

I'm not sure your physics is correct there.

 

When doing a hill start more force is required to move the vehicle forward than when on the flat because of gravity. 'Weight transfer' in this context only happens under acceleration and is not altered due to the incline. It's similar to trying to tow another car out of a muddy field - more force is required to get things moving and there is more likely to be a loss of traction.

Try standing on the side of a hill sideways and you might notice more pressure/weight on the foot that is lower down the hill.

You're comparing apples to oranges.

 

Put a coin on its side on a slope. Does gravity make it fall down the slope or weight transfer? To make the coin go 2cm up the slope how hard do you have to flick it compared to making it move 2cm on a flat surface?

Yawn!
