How problematic is VW's 7 speed DSG?

You can reduce how much it slips, because the transmission tends to shift quickly to gear 2 while the engine RPM would be still low and it has to slip the clutch to prevent stalling. By not inching forward in traffic or holding on to gear 1 for longer periods, e.g. up an incline in many shopping center carparks, you prevent the transmission from slipping the clutch excessively. When people drive manual cars, they don't tend inch forward in traffic or slip the clutch while going up slope -- or at least I don't do that. It's not only bad for the gearbox but generally tiring to be holding the half-clutch all the time. The problem is the general expectation that a DSG should behave like a slush automatic that people end up inching in traffic or slipping the clutch excessively unknowingly. Some people are more sensitive to the car and will "feel" the slipping, some, or rather, MOST people aren't. That's the problem.

 

BTW, I was under the impression that LuK built the entire transmission. So from what you are saying I am gathering that LuK only made the clutch, and the mechatronics is built by VW with parts sourced from various vendors. So it is in effect a "VW mechatronics".

 

Problem with my DSG is that when say going up a carpark slope, you slow down for the barrier to open. Once open, the damn car thinks it is tough enough to proceed on gear 2 and even at low speeds, the paddle shifters refuse to go back to 1. Only way around it is to stop the car totally to force it in 1.

 

Going up the slope at 10kph on D2, I suspect the clutch is slipping at least a bit to smoothen the drive out. Just the 'feel', compared to driving manual.

In spite of what VCS claims, I change my DSG oil every 20k km.

 

Gearbox ran creamy smooth up to the day I sold the car. Mileage close to 80k km.

 

BTW, it's the 7 DSG.

 

This sounds like engine oil le.

The D1 on this gearbox is like useless one... D2 is always the one that does all the low speed job... it doesnt matters as long the car still have the power to move up without jerking... It will auto drag on 1 gear all the way up the slope until the computer/engine/gearbox detect that you are not on a slope or until u really gun it to bring the speed up for the gear to change

To overcome this programming flaw, I just tilt the shifter to manual and it goes to 1st gear immediately. However, the gearbox will tend to be more jerky in gear 1. Else, go light on the gas in gear 2 until speed hits 20km/h to reduce damage on the clutch while they are slipping.

 

According to my feel and experience with this gearbox, the clutch fully disengages after 20km/h. All reports of "vibration" occurs between 10 - 20km/h.

 

Whatever it is, one has to accept that DSG is never smooth in low speeds.

DSG is meant to cheong and zoom zoom in/out overtaking

I would think it is a max fuel efficient programming. My opinion is that the gear ratio for D1 and D2 is quite close so if the slope is not really steep D2 might not be slipping clutch to move the car while avoid killing the engine...

 

Me not expert so any master please advice.

I think it's not for fuel efficiency but for comfort. Car gets very jerky when clutch is fully engaged in gear 1 at low speeds.

Yeah for comfort. But slipping at gear 2 too long generates alot of heat as well as wear and tear.

Hi Everybody Happy CNY,

 

I am very new to this forum here, needed some advices from senior/experienced/like-minded people here.

Am driving a 5.5yr old VW Passat CC 1.8T with about 108k km.

The gear box seems to be down for me on CNY Eve.

 

a. After starting the car, when i tried to engage "reverse gear", the car did not reverse but can only drive forward.

b. After driving forward for about 2km, the car lost power and the gear box seems to "jump gear" from D6 to D4 to D and finally back to normal driving.

c. I continued my journey for the next 20km or so. Did a reverse gear, and it worked.

d. Drove back home and managed to reverse parked my car.

e. The same thing occurred and i did not drive the car till now.

 

VW Singapore did a Voluntary Recall (Replacement of Mechatronics 7-speed DSG) on my car on May 2014. Could my current issues be related to this recall? Contact VW Singapore this morning and they told me my warranty has expired, what redress can i do, and where can i seek assistance to repair the car?

Appreciate your kind advices and comments. TQ :)

You must be kidding if you think AD is gonna fix for you.

[Blackyv]

1) pay from pocket to repair the gb.

 

2) scrap it.

 

3) sell to 2nd hand car dealer (as good as scrap actually).

 

Don't think you have much choices left... Good luck..

[merc280v6]

After 5+ years and >100km, DSG sure bound to fail one!

[thedryvr]

If it's out of warranty, repair cost will be out of your own pocket. That's when you decide if the cost of repair is worth it.

[Arch1984]

My fren got free mecha replacement after warranty after emailing directly to audi saying fault not detected when servicing, end up have to tow etc.

 

You can try emailing to vw directly say gb problem not resolved after recall. Spoil within 3 years. U service at dealer?

sorry to hear that. my guess is the the MU is faulty and needs to be replaced. You can go to VW for diagnosis and get a quote from them for repair.

 

then use this diagnosis and go to 3rd party workshops like VAG to get a quote.

 

if the repair cost is palatable, do it and drive on. even if you want to change car, you still have to get this fixed unless u r gonna scrap it.

 

key is to get the repair done reliably at the lowest possible cost. and if able to, scrap or trade in.

 

i used to drive a car with mechanized gearbox before and i know how it feels to have gearbox issues. the worst was cruising on lane 1 at CTE and then the gear just jumps to neutral and just won't engage. it is super dangerous.

 

good luck!

Hi all

May I know if the Volkswagen EOS have this DSG gearbox problem ? Am planning gets a second hand.

honest opinion.

Ditch the car quickly. Imagine the problem on your 1st gear. while you were going to leave a petrol station along the NSHW at Malaysia Pagoh on your way back to Singapore.

[S4vtec]

how about the S tronics on the audi A4? Is it the same problematic issues?
