Confused over timing belt advice

The car in the video will remain with the valve opening and closing angles the same as before changing the timing belt, so, although it is not the appropriate procedure, it is better than removing the bolts of camshaft adjusters/pulleys and then not using the VAS 611007 tester.

There are many videos (EA211) where they remove the bolts and do not use the VAS 611007 tester...

Yeah, makes no sense to remove them. I've never removed a sprocket to do a timing belt on any engine.
I wonder why the workshop manual calls for this.

Because you have to adjust the cam with the electronic device to be in the spec.

Well yes of course, I get that; but leaving them in place will leave the cam phases in spec.

It's because cam goes out of tolerances over time.
That's why you have to re-adjust them.

Guess I better make friends with a workshop that has the tool then.

Yup you should

Yup you should

I think I know just the guy for the job.
So he is a friend of a friend. They used to go to school together.
And he runs a VW/Audi specialist shop.
But that's not how I know him.

I know him because of his twin-engine 1.8 16V turbo mk1 Golf. 200KW in the front ... 200KW in the back. Amazing.

Of course, that set itself on fire in the workshop... so maybe I should avoid.
