Hi,

I've just purchased an Octavia 1.2 TSI and I was wordering which is the recommended RPM for gear changing (for each gear). Some people recommend (in order to avoid turbocharger failure) changing at very high RPM, 3000-3500, which is so different than maxidot's recommendation. Others, they just say to keep it within max torque before and after changing the gear. This means changing between 2000 and 2500 RPM.

Does anybody have some "official" values?

Thanks.

Depends what you are doing! There is no figure except somewhere between 1300 and 6500 rpm!

Whichever feels right - gives you the acceleration you want, the economy you want, doesn't make the engine labour, and don't red line it every gear change!

This means changing between 2000 and 2500 RPM.

No, this means changing between 1.550 and 4.100 RPM as the maximum torque is constant in this RPM range.

Change whenever it feels right and don't drive it like a diesel...

Maxidot recommendation will be for best fuel economy. With the DSG in D mode the car will change at as low revs as possible but in S mode it will change to keep the car in the engines power band. You can also override both of these with manual mode (but this will not allow changes that will damage the engine).

As long as you are not on the rev limiter all the time or changing up too soon then the engine should cope and should not fail. I would be worried if I thought the engine would fail by being driven within tolerances (i.e. below the rev counter red line).

I got dsg if i feather the throttle it changes around 2000, if i push a bit more it is 3000 if i boot it, it will change near red line, i presume for everyday driving and in no rush 2500

Thanks for your answers. I prefer to have better fuel economy but without damaging the engine/turbocharger.

@slick123: if I switch at 1550 then after the switch it will fall bellow the max torque.

Don't forget that the turbo needs some exercise - rolling along at low revs to maximise economy means the turbo never gets really wound up, so the moving vanes can stick. You need to drive it like you stole it for a few miles at least once a week
