Downhill high revs (118TSI 7S DSG)

[maneesh5880]

Hi,
I have only driven my new Jetta (118 TSI with 7SP DSG) for 800 kms. I have noticed when doing downhill the car will pick up speed. So to keep it within the speed limit, I apply brakes. When I apply brakes, the DSG will automatically drop to a lower gear. When this happens since the car is still in a higher speed than the gear chosen by the DGS, the revs to very high.

Revs remain high until either there is no longer a downhill and DSG will change to a higher gear or I press the accelerator to make it change to a higher gear.

Is this behavior normal / expected and am I doing the right things or I need to change something?

Please do share your experience / expertise with a new owner of such a sophisticated machine.

Cheers

Sounds like perfectly normal and reasonable behaviour to me.

Yep normal behaviour, it behaves as an engine brake and will hold onto the speed you have braked to with less run on. Going down the Maleny range mine will change back to 3rd and hold it at around 70 kph unless as stated you accelerate or manually change up. If it ws left in 7th the vehicle would run on to much higher speeds on the 12% gradient.

Totally normal dude!!! if it annoys you just slip it over to manual mode and select the gear you want if the revs annoy you.....

But in some point you will have to give up to the gearbox anyway and the way that it manages the revs...

Cheers!

Couldn't agree with the other posts more....

I thought it was also werid the first time, but it is really quite logical, the car is actually doing what it should from a safety perspective and slowing the car as you are using the brakes!

Yes they are right, we had a customer complaint of this, had not come across it ourselves as they are quite new and not many hills around us, so whilst roadtesting 2 other stock cars with the same motor/gearbox combo found they are all the same, "downhill decent control" they do kick down a gear on a steep hill and appear to hold the revs quite high, too high for some people as you said the revs take a while to go back down when you have reached the bottom. Also used a works loan car one weekend and found that the same when crusing down the coast last month, so yeh, quite normal design feature......VW..........

Yeah, totally normal. My 118TSI 7DSG Golf does the same. Consider it a licence saver that the car will keep your speed constant. Notice how it shifts to higher gears as the road levels out... it's very cool.

Pity the kick down shifts aren't as sensitive when going uphill... i find it annoying having to put the boot into the pedal.
