Just did my timing belt. Started up just fine. But after rewing the car it develobed a knocking sound. It koms in and out with semi regular interwals. Any ideas what is going on?

2007 1.9. Tdi automatic 270.000 km

See video

How does the car drive? Did you adjust the torsion value correctly using VCDS?

 

If so and it reads zero (the aim) are you sure its a true zero (very hard to achieve) and not an out of limits zero?

 

The value should change when you rev the engine, if it doesn't then its a false zero.

Thank you for your response

I have not driven it (still fixing brakes).

I did not adjust torsion value with VCDS.

I have been googling and I wonder if it might be the flywheel (i revved it quite hard in park). The sound sounds very similar in the videos. And i feel like the sound is koming from beneath the engine not from it.

Finished fixing the brakes and as soon as i started driving it the sound whent away. I suspect my revving in park did something to the transmission and driving it fixed it.
