GTI stall

xathras

Hi, I have a 2015 Automatic GTI. My garage is in an apartment building with a ramp to the 3rd floor to park. Occasionally when going up the ramp and breaking waiting for the automatic door to open I've noticed that the car will fall back a lot, almost as if the car was stalling like I was driving a manual.

Has anyone else observed this?

I have no other issues with the car, no warning or readings at all coming from the car at all.

Seems a little weird

What do you mean "fall back"? You mean the car's idle speed drops, or do you mean the car moves backwards even though it is in drive?

Both, i notice the idle speed go down but the car actually moves backwards even in drive

There may be two problems here. One, you have the DSG automatic gearbox, and it sounds like you are "balancing" the car at the top of the ramp by lightly applying the gas. Your car has "Hill Start Assist" which will hold the car for 1.5 seconds without the foot on the brake, says VW, so I assume you are waiting longer than 1.5 seconds to move off the ramp. In that case you'll have to use the brake or the handbrake to keep from rolling backwards---DSGs have a tendency to do that, unlike "normal" automatics.

As for the drop in idle speed, are you saying this happens only on an incline, and not in regular traffic?

If that's the case (no stall on the level, stall only on a ramp) then that's rather peculiar and if you can reliably reproduce this condition, I'd take the VW tech at the dealership for a ride and show him/her what's going on.

Your rpm gauge should read the same when you are stopped for a red light as it does when you are stopped at the top of the ramp.
