After 2 local garages used their diagnostics and found nothing, I finally took the plunge and paid for a VW/Skoda specialist investigation. They found a problem with the engine speed sensor. This was replaced, but they said that if this didn't cure the issue, it would be a gearbox fault. However, some weeks have passed and I've done about 1000 miles since the sensor was replaced, and all is good so far. Diagnostics, plus replacement, plus labour and retest came to £550. Not cheap, but I'm happy that my car seems fine now......touch wood!

Many thanks for taking the time to reply. I'm not particularly mechanically adept, and I don't have the correct tools, so I can't do this myself. But it's good advice I can take to my garage and ask them to have a look. Thanks again.

My 2015 2.0 tdi has developed an odd, intermittent jerk, like a sudden cough. It tends to happen after the oil temp has reached 60 or so, but not necessarily when accelerating, and sometimes when idling in neutral. Sometimes it will happen two or three times in relatively quick succession, then it may not do it again for 20 or 30 minutes. I've also had a couple of stalls when pulling away from standstill after the car is warmed up. There are no warning lights, and both garages that have had a look have found no diagnostic codes. It's had new fuel and air filters, but the problem persists. However, I bought myself an ODB II reader in the hope I could capture something when the issue arises. This scanner also shows no error codes, but does show a TP(%) of 89. Could this be a throttle sensor failure, maybe affecting the ECU and causing the jerking? I'm not enjoying driving the car, as I'm on edge waiting for the jerk, and I'm a bit paranoid about going on a long journey in case the car lets me down badly. Any ideas will be gratefully received!
