Where did I go wrong

In the midst of learning all things IFR. I had a little issue last night and am trying to understand where I went wrong.
My instructions were as follows:
Cleared to X airport
X Departure
X intersection
then as filed
4000
expect 6000 1 o minutes after depart
freq
squak

So here is what I did. I looked up the departure which called for a climbing right turn to a heading of 213.
Upon takeoff i made a climbing turn to a heading of 213. Then preceded to make a turn to the given intersection. Shortly after the controller told me I was to be on a heading of 213 and to get back to it.

So is that where I made the mistake? I should have simply stayed on the departure until he gave me specific instructions to head to the intersection. I am pretty sure that was the mistake but that was the first time I ran into this and am unsure.

It woudl've been a little easier to provide support if you included the specific departure and airport, but based on the numbers, I'm guessing it's the VNY SID out of BUR?

If so, please read the the TEXT of the departure. What does it say?

Some advice, if I may, do not show up on the network and fly a procedure that you would not be comfortable excecuting in the real world. The network is not really designed to learn these things on the fly, or learn by experimentation. We need to try to avoid cases where the rate of deviations on the network vastly exceeds what happens in real life.

To that end, I'd suggest utilizing the myriad free training offered by the workshops and I-Ratings, linked in the signature.

It's a pilot nav departure with a vectored segment. You ignored/missed the requirement to wait for the vector (as required by the textual portion of the SID).

It's also fairly logical. Without the vector, when do you turn to the first fix? If it's immediate...then what is the point of the 213 heading? :)

Keith thanks for the reply. In looking over everything I did again and your statement is dead on!

I just need to slow down and go back over my learning materials better. No matter how much I have learned I still find myself needing to take more time and dig further. In the future I will do so.

Thanks for the help!

The 213 heading with the assigned altitude is a safe heading to avoid obstacles ( mountains ) while in IMC conditions ( IFR ) until ATC has a moment to vector you and other traffic. There are many SID's like this. Look at the KCLT "BOBZY 4" SID. Its an RNAV Dep with an initial heading dependent on runway. Same idea.

Not so much the 'has a moment', but until above the 3k MVA for the area, and then there's the question of where they vector you to. There's all manner of potential shortcuts.

Ah 3k MVA. That makes sence.
