Hello.

A quick question for you guys.

Is it any strange sound on the engine? Or shoud it just be like that?

Flywheel?

Afraid of that too. But my car have just run 50.000 km (30.000 miles).

The car is a 2015 Octavia with 2.0 l, 150 hp diesel. Is the flywheel a proble on this engines?

I also have a low "knocking"-sound inside the car, when the vehicle is idling. This knocking is just in park and normal. When I change it to drive or revers this knocking goes away.

Still in direction of the flywheel?

Sounds a bit rough to be honest, no idea on cause but sure it isn't supposed to sound like that..

My (very amateur) guess would be the chain tensioner. You say that you have done 30,000 miles, it has been serviced with appropriate grade of oil, right? I wouldn't expect anything to start knocking until you approach six figures in mileage...

I would say it's the DMF for sure - I'd get it looked at sooner rather than later as it sounds like its breaking apart.

 

Not uncommon for a failing DMF on diesel cars

Sounds like lash adjusters or rod bearing. If the sound goes down on rev then highly the lash adjusters wich is ok, it is just noise,need to get the timing belt off though to change theme but if it increases on rev then it might be the rod bearing... This is more expebsive... But it sounds more like the lash adjusters.

Dual mass flywheel, knocking on idle being the main clue.

This. Plus the fact it disappears when drive engaged
