Thought of the Day :

Maybe it is better to drive in stop and go traffic in D mode as the gear goes into 2 at about 1200 rpm. Stop and go traffic puts lots of wear on the clutch plates. The first clutch plates tends to get the most wear as it is always the starting clutch. Therefore the clutches should wear unevenly.

The function of gearing up at lower revs from 1 to 2 especially in stop and go traffic would probably help share and even out the wear and friction between clutch 1 and 2. Therefore extending the lifespan of the clutches as the car will roll in gear 2 at revs below 1000 rpm.

DISCUSS!

[EcoTune Trinidad]

Agreed...as per manual they say when the speed is too low,use the tiptronic mode to manual shift down...

I have noticed in tip mode the gear shifts dwn to 1st at around 20km/h versus drve mkde which shift to 1st only at complete stop....
Also it is good practice to use nuetral gear at every stop to maximize the cooling of the clutches and slow down wear from stop and go traffic...

[drchaos]

Question :

Does depressing the brake pedal fully disengage the clutch pack? Just like in neutral gear or is neutral gear different and allows for faster cooling of the clutch packs?

[EcoTune Trinidad]

It reduces clamping pressure,but doesnt fully disengage it as opposed to using nuetral...only drawback is delay in accel between changing gears and moving off the line.
I saw this same thing being discussed on vag.uk and vortex forums and it seems to make sense.....

[Ted_v2]

How much you guys looking at for a transmission rebuild?

[drchaos]

Dunno about rebuild but the cost a new clutch pack is $13000 and I would shudder to think about what the installation fee would be.

Should be free under warranty tho

[EcoTune Trinidad]

There is a company from Miami which sells aftermaket clutches handling up to 600hp.....for only US$1049...The dual mass fly wheel will run half that but these dont give out that easily

[drchaos]

Eco u could install DAT clutch pack if I buy it boy?

[EcoTune Trinidad]

For double the price Best Auto charging I willing to try...

But seriously if these are this affordable, I may very well push my engine to 250hp though

[neexis]

You still eh do that yet?!! you sticking man Eco

[EcoTune Trinidad]

Not sticking neexis.....believe me I am eager to tune this...but I will need better tires and at least 18 inch wheels..new engine for 2013 (CTHD - same as 2013 Polo GTI, not CAVD like 2012 backward)means BA will be installing SW updates which will wipe my tune...which means I have to go through the daunting task of re-opening my ECU....I prefer to do these procedures once and leave as is in order to maximize the effect of resealing properly...

You already know the ECU location does in fact get some moisture from rain via the water channels along the fenders and near the wipers...

[EcoTune Trinidad]

My personal opinion is that tuning is a good thing IMHO....

When I read all the horror stories about shuddering I am thinking when we creep forward especially in traffic, the mechatronic tries to alter & vary the clutch pressure values so rapidly that over time of constant creeping forward from traffic and not enough hammering on the open road; the clutches become glazed which result in "slipping" or "shudder"... and may not necessarily be a mechatronic issue...remember these gearboxes are designed to prevent the end user from experiencing clutch slippage as much as physically possible by adapting to clutch wear.

An example would be under WOT, if the DSG clutches detect possible slippage,it will change to the higher gear which lowers the torque application to the clutch...

My reasoning is by keeping the clutch pressures at a constant value in between throttle application would eradicate these symptoms, make pull off more sudden and/or aggressive according to throttle input...

You may ask why haven't VW make it this way to begin with?It is because as it stands now, the stock clutches are designed and installed in a way to give approximately 400,000km

I am not sugar coating anything, but by changing this to make it more sensitive would obviously mean this 400k km would be reduced - How many KM ? I cannot answer this, but I will say its according to how you drive it will decide it's life expectancy...but remember clutches are a service replacement part like any other manual transmission car...

Same problem I'm having on clutch #2 heavy slipping. Especially on 60%+ throttle in 4th gear.
Only work around right now is a light foot

[drchaos]

I have a spit second of less than full power to the wheels when taking off, does't jerk or shudder/judder just that split second. Noticed thats its more pronounced 8 1/2 months into the car. Its not bothersome and corrected by mashing down harder on take off.


but just something i noticed ... wonder if its clutch slippage

Yea I noticed it with my car..but 1st is t built to run high up into rpm range...

From consulting my owner manual...it warns to never under any circumstance run 1st gear hard....its evident when it shift into 2nd under wot at 4000rpm or thereabouts..if its that you meant...

What page? I run 1st gear to redline in manual mode
Heck sports mode runs past the redline for itself.

[drchaos]

Yeah I am really not a fan of sports mode!

Its runs really deep into that red line and I know that can't be healthy for the Transmission and Engine.
Would normally run D or Manual mode for super happy fun times.

[Allergic2BunnyEars]

If VW allows it I am all for it. If it really was that serious then sport mode wouldn't run deep into the red.

I checked through most of where I think they would mention it in the manual and I can't find it again ..

But from memory they specified tip tronic mode to desist from running 1st hard as it will extend clutch wear - (highest torque load on low a gear will eventually wear out the 1st clutch)

Or maybe I am mixing up what I read in other DSG documentation? ...either way I drive by what I remember

I'm interested in buying the Jetta 1.4 TSI from the firm.
Whats the gas mileage like? I've heard people say they can get up to 700km of a tank.
Is this realistic?

Realistic dependent on your driving habits basically.
I have gotten as much as 779 km from a tank. This is more highway miles than city. Aircon used during the day. Sometimes not used at night. Cruise control whenever possible. Coasting before braking instead of braking harder when near to a stop. When foot isn't on accelerator the car cuts fuel to injectors. Average highway speeds of 100 kph. Couple blasts to 200 kph but not sustained.

Short trips, traffic, stop start driving, sustained high speeds (140kph+), heavy acceleration are all going to bring down fuel econ. With this type of driving expect about 500 km per tank. With more highway mileage I do think it is possible to get 800 but one would really have to plan out their driving to avoid heavy or standstill traffic.

Think allergic got near 800km if memory serves me correct...he will confirm

Thanks for this,I won't be doing to many highway runs.I guess its a pickup then.

This could be your future if you buy
Clutch built to last 400,000km
DSG/Mechatronic maybe a bit less /s

any background story? mk5? mk6 Jetta? Passat? I'm always up to hear about mechatronic failures locally.

[drchaos]

From what we have heard the mechatronics unit has been beefed up and if it fails then they fix it! and they HAVE to give you a car to drive in the mean time until the part is ordered

MK6 Jetta

Let us know how it turns/turned out.

I'm just disappointed.
A Ford Cortina would not require tranny work so early in its life
