When I just start the car (cold engine), the car seems to be working incorrectly, shaking, as if it were nozzles?
But the car after 4-5 minutes of work goes quite normally, even pulls well, no driving problems.
What can it be?
Maybe diesel injectors? PCV valve?
By the way, it's like I hear a little alternator.

I enclose a video of the operation of the engine.

Any advice how to resolve this problem?

Thanks in advance

This is normal on a TDI
My 2.0 will vibrate a little on start up.
Its a lump of a diesel so it will run a little rougher.

My car Idiles just below 1000rpm as well.

If this is not normal I got the same problem as you LOL
 
Bro this is not normal :)
When its on idle, rough idle, but after 5-10 min, or driving, when turn off car, and turn on, it’s normal start, so smooth.

thanks on reply
 
Yeah sorry I listen to it again, thats not normal.
Have you went to a garage to see whats wrong, or plug it in for errors?
 
Have you recently had any belts replaced or needing replacement?
It does sound like something is rubbing or ticking which could be a loose belt or worn belt.
I'm not a mechanic, and most on here would say get it to a garage ASAP.
Sorry I couldn't be more of help.

Sounds like a misfire. If it's restricted to cold starts only, it could be a failing glow plug(s). Modern diesel engine glow plugs not only heat-up to start the car but also carry on being hot for up to 5 minutes after starting to help with DPF heating and emissions.

Thanks bro on reply, It's mean alot any help :)
 
Hi, did you manage to get this problem sorted out as my Audi is doing exactly the same thing. It doesn’t do it on every start but it’s so annoying. I’ve also had diagnostics done but nothing showing! Any help would be appreciated.
Thanks.

Hello brother, I know how this is frustrating :(
I use aditives, wynns, nothing help, vcds show no problem at all, no error code
But, in Delphi software for cars on my friend garage show bad fuel injectors
Now is even worse on cold time, -5c, or -10c
Must send all injectors for cleaning? I hope this is help
 
Hi, did you send your car for injector cleaning and did it fix the problem.
Thanks.
