Problem 1.2 TSI - Vibrating/Shaking when cold

Hi,

I have a problem, three months ago strange vibrations/shaking appeared when the engine was cold app. to 70-80 degrees (morning starts) at idle. Vibrations are appearing on 3-6 seconds. The chain noise is normal and also the RPM are normal.

6 months ago the chain was replaced, two months ago i had an EPC light and they changed spark plugs, cables and the Ignition Coil. Chain was replaced two times and also two years ago the chain tensioner was replaced.

Today I left Fabia at my local dealer to see what is the problem. But anyway does someone have any suggestion what could be wrong?

Engine: 1.2 TSI 86 hp

Year: 2011

Milage: 58.000km

Thanks
