For some time I have been experiencing shaky / rough idling happening occasionally (cold or warm engine) with rpm needle jumping up and down and you can feel the engine shaking though the car seat (but its not a regen) .

 

This happens regardless of being in park, neutral or in drive with foot on the brake.

 

Today, my engine also stalled 2 times while stationary (I have never experience this before on my car, moreover because I have a DSG)

 

I have some videos filmed with my phone, you can see the needle shaking, and if you enlarge the volume, you can almost hear something from the engine bay rattling.

 

 

 

Has anybody experienced something similar?

Mine does this but only on a re-gem, mentioned it to the dealer on the first service and again last month, i was told its where the engine has unburnt fuel, it is lumpy to the extent i thought the kids were fighting in the back. 

If it has unburnt fuel, then it overfueling, so it might be injectors issue?

@toni8b Did you ever get to the bottom of this? My 2015 Octavia 1.6 TDI DSG is doing this on cold mornings, it's been getting worse over the past week and now unless I really push the accelerator whilst in Park, the engine will happily stall when it should be idling. I'm going to take it to my local garage and leave it on their forecourt overnight so they can experience the problem first thing in the morning... but it'd be good to know if you figured out what the problem was.

No, I havent solved it but it hasnt stalled ever since it happend once. Rough idle still happens sometimes but too occasionally to be able to show it to the dealer. I am sure one day when the warranty runs out I will find out what is the issue.

My local independent garage couldn’t find a problem - they experienced the cold start but after a few hours tinkering couldn’t find a problem. They wondered if the fuel injector was faulty but it would be a guess as there’s no fault codes coming up, and it would be an expensive guess to replace without proof.

 

The car had new oil, fuel and air filters a month ago, so maybe one of those is dodgy - that’s my only remaining theory.
