Hey! I have the same problem on my 2012 Skoda yeti CBZB (1.2tsi) code engine with manual 6 speed gearbox. There is an rattle/vibration only on 5th and 6th gears and only from around 2200 rpm to 2700 rpm, before and after this rpm everithing is fine. The spark plugs and lids are new, the timing chain are new, the engine and gear mounts are new and more parts, the car is well served. I have this car for a year and a half from 74,000 km to 97,000 km for now.

Here they wrote that the 1.2 tsi cbzb comes vs DMOOon the yeti. https://www.honestjohn.co.uk/forum/post/?t=92637

Sorry forgot to write, the spark coil also new.

No chance that the rpm to low, before i get to 2200 rpm there is no vibration. It's possible that the vibration coming from the wastgate?

Thanks for the riplies! Forgot to say that the engine mounts and gear mount are new and after i changed them the situation feels better = less vibrations. The spark plugs and ignition wires are both new! I dont think that it's the tires because the vibration changes vs load on the throttle.

Hello! I bought second hand skoda yeti 1.2 tsi 2012 (105hp) vs 6 gears manual gearbox. Since i bought the car i have one issue, when i drive the car in 5th and 6th gears from 2200rpm to around 2800rpm i feeling vibration in the car, or from the gearbox or from the engine. The vibration gets stronger only when i pushing on the gas. Started to think is it possible that it's the Dual Mass Flywheel? The car vs 80k kilometers. Also changed the timing chain and more.

O.K. been in the garage for changing timing belt, also changed the spark plugs, spark lead and spark wires. the problem is still there when i drives the car on 5-6th gear from around 2000 rpm to about 3000 rpm. there is light vibration that you can feel in the car and some louder noise from the gear or the engine.

Really don't know, need to look in the car servichihistory from the previous owner. Is the simptoms sounds like it could be the spark plugs or the ignition leads? What model of spark plugs goes on the 2012 1.2 tsi engine? the engine type is CBZ.

Hello! I'm new here, have the same problem on my 2012 Yeti 1.2 manual gearbox, the car now vs 72k kilometers. Did you found the solution for this problem?
