DSG Gearbox & Manoeuvring in carpark

It's programmed with certain set scenarios, but DSG/auto gearbox cannot see what's ahead which a manual driver can and choose to shift or not shift accordingly. One day when it can see ahead and make decisions, then I call it improvement.

Nowadays the gearboxes will do the thinking, they think for you so they will do what is right for you and themselves so leave the job to them and just focus on your part, left right straight or reverse

I wont be surprised those that give lecture do not even own a VW.

Is it bro? Read people drive more than 10 years and more than 200000km the gearbox no problem...

Those are torque converter or cvt trans without physical clutch packs

All technology need user experience and time to improve on it. Be it Manual, CVT, Torque Converter, DSG etc..

 

I remember 10 years or more back Toyota never wanna ship it CVT models out as in the event of recall or rectification, it be more cost effective and efficient to do in the local Japan Market. Nissan If I not wrong is the first few to export CVT box oversea. Those earlier Toyota CVT are brought in by PI.

 

Of cos VW could do more on their DSG.

 

If one is not prepare to be part of this experiment they can always go for other make/model with more proven gearbox.

For driving in stop & go traffic and going slowly in a carpark, what should be the safe way to drive with a DSG gearbox?

 

I'm a bit confused about stopping completely then flooring the pedal. Wouldn't this sort of driving style be quite dangerous?

Why so complicated? Driving auto, you just control on your acceleration. Going up slope, you just accelerate as you go up and release acceleration as you go down/slow down. DSG change gear fast and smooth compared with other auto gear, that's all...

I am new to a DSG gearbox (been only a week) so would welcome some advice.

  • When going up the incline in HDB car park, my VW Golf 1.4TSI seems remarkably reluctant. I do know why this is happening - as I approach the incline I need to slow down (brake) and turn right to get onto the slope. The DSG gearbox thinks I am going to stop, so it is not in the right gear as I complete my turn. Opening the throttle slightly does not move the car up the incline, and with more throttle it moves too quickly.

  • Also I have noted that when going down the incline in HDB car park, when you take your foot off the brake, and step on the accelerator, it seems reluctant to get going again. Again, I do know why this is happening... the DSG gearbox thinks I am going to stop, so it is not in the right gear as I complete my turn
Have you encountered the same issue, and do you have any techniques, or is it just a matter of getting used to it?

Been driving AT & CVT, and none of them had this issue.

 

Thanks in advance,

Naresh.

What is your mileage? Could be yourself not used to the friction on new gear and brake? Give yourself around 2000km for smoothing out the new gear and brake. Just drive DSG the way you like it... Enjoy!

Some would recommend put into gear and not let it row, really stress sia.

 

I have my fair share of failed autotrans, all torque converter type. E.g. mit, Honda, bmw...... So do not assume they are as good as many made it out to be

When the gear is in D, the stress is applied to the gear even when you are stepping on the brake at stationary. Unless you are in heavy jam, common stop and go slow traffic won't do much harm on auto gear. They are designed to take on such stress. Dry clutch DSG have history of heat buildup which VW had made some changes on the transmission fluid used and patch the gear engagement sequence to help prolong the wear and tear

When you approach a ramp in any MSCP, naturally you need to slow the car down before making the ascend.

 

No need to stop completely, just need to slow the car to enough speed that the gear is lowered to D2 or D3 can already. Do it a few times you will get the hang of it.

During stationary and in D with foot on brake, isn’t the clutch disengage?

Gear is always engaged during D unless in P or N for automatic transmission. Stepping on the brake does not "clutch in", the action will reduce speed and cause gear to downshift.

Stepping on brake when stationary the ecu will auto engage N, u can feel it. Some can see their rpm will know. It’s only when u on handbrake and D , Sen the gear is engaging n got force to go forward Edited by Dannnn

Yes. Due to the ecu control in golf, gear will dis engaged when brake applied and car come to a complete stop for a couple of seconds. Not every auto car do this. In layman's terms, for auto gear, D is always in gear. Therefore, in heavy jam where you need to brake and release in short timing, is harmful to all auto car gear.

While the gear of a "standard" automatic transmission is "always in gear". The design of the transmission with the torque converter actually means that it is capable of creeping forward at glacial speeds, all day, for miles on end, without any extended clutch wear.

 

The reason is that if you look closely at the design of an automatic transmission, the torque converter is free to rotate even though it's "in gear" while the rest of the transmission stays stationary. This is an inherent design of any "standard" automatic transmission and is what gives it its characteristics, both good and bad.

 

The greatest harm you could do to your automatic transmission is to put it to neutral, and then attempt to launch it by revving it to 6k rpm and then engaging the gear in D.

 

Don't get me wrong. As with most things in engineering, it's a Yin and Yang thing. Like the Dual-clutch transmission, the automatic transmission is not without its flaws. It absorbs a significant amount of the energy entering the transmission (the torque converter), and hence an AT car, even if the weight were the same, is always thirstier than a MT. They are also somehow "less involving" to drive as compared with a DCT or MT.

 

At the end of the day, know what you have, and care for it accordingly. Your car will reward you in the form of the clutch not s***ting itself prematurely.

How slow do you get before you mount the incline slope? 15km/h? 5km/h??

 

if you are really at dead slow speeds, i could imagine the lethargy you experienced since the car is trying not to let you pocket rocket front and back like when you are parking right??
