How problematic is VW's 7 speed DSG?

Yes, I meant when you brake and it rapidly shifts down 4-3-2-1, its almost like engine braking using manual gear. Don't like that 'jerking' effect. Maybe the car is old/worn and it didn't auto rev match. It is much smoother if I just put to N.

 

Why do you need to do rapid shift down?

 

Juz step on the brake is enought, right?

I take it that we are assuming its the 7 DSG dry right?

 

Assuming it can indeed minimize the judder & extend the MU life, in SG, we'll be using the manual override function very often; though with paddles, it should still be convenient enough.

 

drive on gear 1 would be jerky....like driving a manual on 1st gear without half clutch

 

drive on gear 2 would be smooth but lack power and may judder when need to pick up quickly

 

very similar to manual box

Unlike a conventional auto, is there any harm in shifting a DSG to N when braking to a stop?

 

I don't like how the engine braking can be a bit jerky when braking from say 60kph to a stop at the lights.

 

If I shift to N and just modulate the brakes, I find the stopping much smoother. But does this kill anything in the box?

 

Saw a video before about how an automated dual clutch works.. like the DSG from VW / S-tronic from Audi / PDK from Porsche / 7G-tronic from Mercedes Benz. At a stop, you don't need to engage Neutral because the computer does it for you already. Not sure if there's any damage done if you still go ahead & do it.

 

In the video, it strong advised against letting a DCT like above, creep forward. You either accelerate or come to a complete stop. Frequent creeping forward will result in a lot of premature wear & tear. And a lot of local drivers like to do this at the traffic light.

For no frequent creeping forward, does it applies to wet clutch as well?

 

In MT, frequent creeping juz shorten the lifespan of clutch only.

7GTronic on C, E, and above is not dual clutch. 7G-DCT on A, B, CLA, GLA is.

In this case, its back to square 1.

It's not normal if u brake in D mode n the auto trans downshift itself when not at the programmed rpm. I thot u switched to manual mode n downshift. U drivin an Audi? My ride when left in D mode will downshift but at speeds that don't present significant engine braking.

Solution would be to engage first gear, lightly accelerate, then downshift to N and creep. Very tedious indeed. Almost like manual, except DSG wouldn't need to press clutch pedal.

liddat drive GB even if no more problematic, driving in itself is problematic! Must well drive manual, more intuitive.

Paddleshift may be overridden after few seconds of no shifting detected iirc. Best still switch to manual gear selection.

I support, but very few models have manual oredi. Many carmakers into dct oso. Some more manual cars resale no good due to less demand.

very complicated...

 

my solution is when coasting in carparks just use D

 

when filtering, use S or M or paddles

Any solution for queing to make a turn and also, going up a few levels of mscp?

Or shift to manual at the stick, then use the pedals?

It was mentioned it will have premature wear and tear on the entire transmission esp the clutch if do frequent creeping, be it wet or dry clutch. Just that wet clutch overall is more reliable.

Yup that's the right way. D mode with some accelerator input. If creep too much with a DCT onboard, it's gonna get premature failure or frequent clutch replacement.

Thanks to VW, autotrans driving that's suppose to be more stress free, now become more stressful.......seriously.

If like that, DSG is rubbish. I had MRS SMT for close to 2 yrs. I always creep. Not premature wear up to point I sold it

don't worry so much

 

D is sufficient for regular daily use ... just a bit lazy to downshift when there is minimal accelerator input and sudden acceleration is required. switch to M when you think you are going to need this.

 

for going up steep long ramps, the dsg will auto downshift to d1 if speed becomes too slow. otherwise switch to M before you go up if you don't like to get bogged down by d2 midway up

use auto hold. stop means stop. go needs accelerator input.

 

no creep. ha.

 

actually why worry so much... clutch is a wear and tear item even for a manual car.

The only creep I know is the road hogger on the right lane in front of me....
