Default ABOUT DSG(D35)the Maximun Torque???

Dear Sir:

Sorry, our English not very good, pls forgive our poor English skill and pls try to understand our english.

Our Passat 2.0 TDI (B6) Year 2006, is using DSG Gear boxes.
And the VW dealer in Taiwan says the maxium torque for this DSG is 35kgm only. ( and all the DSG data here also shows 35kgm only)

The original Passat set the torque is 32kgm,
ABT chip set to 35 kgm.

But others chip company such as chiptronice or superchip or MTM or TTi....their torque is upto 38kgm.

So we are wondering that, if we change the chip ( not ABT), can our DSG can be accpet? Or if the torque is more than 35kgm, DSG will easy get broken?


I am sure you should have more information and experence than here, Thanks for your help.

The DSG torque limitation is due to the wet clutch packs' ability to transfer the power. Exceeding the design limit of 350 Nm (36 Kgm) can cause the clutches to slip, overheat, and cause expensive damage sooner or later. Stock torque for your Passat should be at 36 Kgm if you have the 170 PS engine.

If you want to make more torque, you would have to replace the clutch packs with those rated for more power, which would be difficult to accomplish.

Dear Jerews,

In Taiwan, PASSAT TDI we only have 140ps engine with 32(Kgm), and if we use ABT chip will goes to 170ps (34-35Kgm).

But the most famous chip such as Chiptronice or Superchip or MTM or TTi, they make the torque up to 38Kgm, and the dealer says: in Eurpoean country they are doing the samething.

Is it really ture, and is it alright for our car?

Thanks a lot

The chip maker is correct that many have exceeded the limit. I wouldn't recommend it. You'll probably wear out the clutches much faster and will probably have to reduce the fluid service interval, which is already expensive enough.

Your options, if you want to work within design limits (minimized failure risk) are:

Upgrade the clutches (horrifyingly costly).
Limit the torque to 36 Kgm (350 Nm). That is the 170 PS stock torque.

Take note that when the chip exceeds the torque limit, the condition exists at very high (near maximum) load conditions. Damage would occur when pushing the accelerator pedal all the way to the floor in manual mode in top gear, or whenever pushing the pedal all the way down while accelerating. If you avoid generating maximum torque manually, you can avoid the damage, but why make the engine capable of causing the transmission harm?
