I have a problem with DSG gearbox on Skoda Octavia 2013. 7 speed. When it's cold and the car doesn't start for a day or two and I don't warm it up, it can throw an error on the DSG gearbox and stop completely. I turn it off, turn it on, warm it up for a few minutes and drive normally. That yellow electronics faucet burns for a while and then goes out. Diagnostics show intermittent problems: Throttle valve actuator - open circuit, cooling system pump for charge pressure cooler mechanical failure, airbag control unit. And that's it. The error doesn't happen often, it never happened before the winter, once last winter, a couple of times this year, but it's unpredictable.
It happened once, so I turned it on again and started to switch manually. He threw the error again in a minute while in 3rd gear on manual without shifting, during normal driving.
This error was often accompanied by seat heaters, heating and other things that draw electricity at low temperatures being turned on.

Now since some mechanics would immediately change the mechatronics or the entire gearbox, what things could I fix before that.

I read various things, but nowhere exactly this situation, from thermal sensors, heaters, fuel flow, air, oil density in the gearbox and mechatronics. When I changed the oil before the 30K service, it was completely liquid, imperceptible, the gear change was not felt at all, now it is felt a little, but no big deal, I also drove other automatics, that's it.
Another problem that could be related, when the car is cold on the back it shakes a little, later it calms down.

Get the battery and alternator checked out first.

What engine do you have?

@okaneloWelcome.

 

No oil change was due at the 30k service on the DQ200 7 speed twin dry clutch DSG, if that was what was done.

 

Best sort out the electrics on the car / engine before having anything done to the DSG,

 

?

Did your 2013 DSG get service campaign '34H5' carried out on it any time after 2017?

This was a software update on ones from 2013-2015.  Carried out free.

 

...............

When people do change the oil in a DQ200 because they want to then there are 2 oils to change, 

in the box and in the MCU.  This is different from the wet clutch DSG which has the same oil doing the job.

I bought a car in 2020 with 208,000 kilometers on it. I didn't do the software update. I will contact an authorized Skoda service. I changed the oil at 225,000 and now I have almost 260,000 on the clock, so I thought I should change the oil in the gearbox again. This only happens at low temperatures when I don't start the car for a day or two.

I am not sure if good oil was put in, it should have been but it was not done at an authorized service center and not sure if any updates were done

What engine do you have?

??? Why was the DSG serviced.  Was it faulty then or did the Dealership staff wrongly say it was required? 

 

Were both oils changed?

They told me that the oil in the gearbox and mechatronics must be changed. I bought the car and wasn't sure if the previous owner did that service so I requested a replacement myself. Both oils were changed. I had this error again this morning. I didn't start the car for 2 days, it was cold and I wanted to move to the parking lot before driving, I put it in reverse and the error appeared. When the car warmed up it ran normally. Should I change the oil again at an authorized service center and perform an update?

I already said that the car shakes a little in N - ler when it is cold. Could the fuel flow be a problem?
