I have a superb iv 2021 90.000km With dsg gearbox and about 15-20 times last months i have had a problem that the car Wont stop even tough i push the brake pedal. 
Its like you drive a manual gearbox and forget to push down the clutch pedal. 
 

When it happens i push the brake until a noise from gearbox/electric engine comes and the car stops. 
 

it happens only when i drive With the electric mode. 
 

The car has been to Skoda 2 times for this and they found nothing. 
Now they sent a question to the factory about the  problem. 
 

Could it be brakelight switch that Dosent send info to dsg or solenoid in the mechatronic that dosent disengage the clutch?

 

Am I the only one who has this problem?

Is this when the battery is full?  Common issue with this platform due to there being nowhere for the electrons to go when pressing the brakes pedal.  In this case you have to press quite hard to fully engage the mechanical brakes and it can feel like the car is pushing on like you describe.  This is especially apparent as the brakes are usually cold at the time.

Last time it happend was after a long highway driving and the battery was empty. 
I drove in to a supermarket parking area and tried to slow the speed down going to park the car. But it was like i forgot to push the Clutch pedal down. 
A mecanical noise came from the engine compartment and the car stopped normal after this

@Superb_iv   Did your car get a Brake Fluid change @ 3 years,    (Now that is at 2 years i read on here.)

& has the DQ400-e DSG had it's service at 65,000 km / 40,000 miles?

Is this a reference to regenerative braking not being available?

Have you checked if the brake lights work when pedal pressed?

Brake fluid changed aug -2024. Dsg service has Been done at 60.000km

 

Its very difficult to se if the brake lights turn on when it happends. 
 

It must be the switch (brake light) or some solenoid for the clutch in the mechatronic?

Do anybody know of the clutch for the electric engine always is engageged and the motor just stops rotating when you stop or does the clutch realese the engine from gearbox when stopping 

 

This is a intermitent fault and i cant provoke the fault

I meant testing the brake lights a number of times while stationary - should give a reasonable indication the switch is operating correctly, or not. 

Yes brake light works but it might be a 4 cable switch, 2 for brake light and 2 for ecu/dsg unit?

In the main screen there is a section called something like "My vehicle". It shows a picture of the whole car. I noticed recently, I think, that if you have the picture displayed when driving (who would?) then it shows the brake lights coming on and off as you go along.

 

Might help you see if they are triggering on the move.

I think its a 4 pin connector switch, 2 for brakelight, 2 for ECU/dsg. 
so even if the brakelight is on the ecu/dsg might not know that brake is applied.
