    Twincharger 7DSG - Selects higher gear than it should. Thoughts?

    When the Twincharger 7DSG is operated in "D", it will readily run at lower revs and a higher gear than most of us are used to. As anyone who has one will know it will climb a hill in 7th gear at around 60kmh and 1300rpm.

    There is a notion that with the Twincharger 7DSG operates at low revs in a high gear under load "..you are putting too much strain on it and that its bad for the engine."

    Not sure if other 7DSG drivers experiencing the same issue of having a higher gear than what it should be. At the moment I either drive it in S or if i see a hill coming, i would accelerate more, forcing the DSG to downgear(s)

    I disagree with this notion for the following reasons:

    1) you are applying anochronistic thinking to a a cutting edge piece of technology. We are not talking about a 20 year old holden with a manual transmission.

    2) I find it hard so believe that VW would design a car with a highly advanced powerplant and automatic transmission and then forget to configure it, so that in its most automatic idiot proof setting "D", it will allow the driver damage it when driving uphill in a liesurely manner .

    3)The ECU on the Twincharger and the 7DSG's Mechatronics unit will have all sorts of sensor imputs. I do not believe the designers would allow them to so readily operate in a regime where it could damage itself.

    4) The engine is said to develop maximum boost (not torque or power) at a meagre 1500rpm so surely it is designed to run under load in this regime. see Inside VWs twincharger

    5) My take on it is, the noise you are hearing is a characteristic of the Twincharger + 7DSG. It might be the supercharger or just the engine itself under load, but I reckon it is quite acceptable and I am happy to drive my car in this range until someone can give me a good reason not to.

    As always - happy to proven wrong. Can someone with specific engineering knowledge of these engines clarify this for us? Thanks...
