Hi.

 

I have a problem with my superb(2012, 2.0 , 147kw, automatic DSG). When i try to accelerate on speed it starts jerking. When engine is cold, not so much. And when the engine is warm and car is stationary then i can feel how the engine does some kind of jumps or something, it does not do that with cold engine. I assume it is not related to transmission.

Anyone has any ideas what could be the problem?

Welcome.

 

Is this something new happening?

How many Miles / Km has the car done?

 

So is the engine serviced correctly, and has the DSG been serviced and had oil changes @ 40,000 miles / 64,000 km? 

It kindof started after winter. So maybe a couple of months. Whole winter was ok, no problem at all. 

It is over 200000km, cant remember at the moment. 

About the engine service id say it is done correctly yes. Gearbox time has come, i must go anyway beacause i found out that the gearbox lid has a very small leak of oil. 

For an example, im driving 70-80km/h and 6th gear, then i want to take over someone, i start to accelerate and it starts jerking. But if i shift manually down to 5th or 4th then it does not do that. So the car doesnt like low rpm. Weird thing is that when i let the mechanic connect the pc to car it didnt show any mistakes

There is the same oil in a Wet clutch DSG, in the box and MCU.  (Different from the Dry clutch DSG's which have 2 oils, separated.)

 

So if you have a leak you likely have a loss of pressure with the Mechatronic Control Unit.  

Needs addressing then. 

Thank you. I'll try to get that looked at and give feedback here. Hope it is because of that.

Hi.

Got rif of the leakage but not of the jerking.

Any more ideas/suggestions?

Do you have a petrol or a diesel engine? Might be relevant to mention that...

Yeah, sorry,my bad. It is petrol.

 

I am assuming that you have not yet done a diagnostics check for error codes?

 

If this is the case, try to get hold of VCDS, which should pin point the problem.

 

If it throws up a code for the Mechatronics and assuming that the gearbox has not been serviced at the correct intervals, start with a gearbox service, replacing the fluid and filters.

 

Remember to clear the codes afterwards.

The mechanic connected the pc to car, searched for errors, it didnt show anything. At least he told me it didnt.

Im starting to suspect that it has to do something with the fuel system. Maybe the injectors or the pump itself. That the engine doesnt get the right amount of fuel 🤔 Or if it has something to do with that then it should show up in errors list?

Got my **** together and took the car to skoda service.   The problem was in the ignition coil (i think that it is translated like that) on 3-rd cilinder.
