Judder when pulling away
Hello
Lately i feel a lot of juddering/vibration when pulling away in first gear. It gets worse when the car gets in temperature, and it feels worse when pulling away fast(relatively high rpm) and when pulling away uphill.
The judder feels trough the whole cabin when i start releasing the cluch till i completely take my foot of the clutch. When shifting other gears feels just fine.
Any idea ?

Following cause mine is doing the same thing, although it's not really consistent for me and seems to do it more when cold in my case. I thought my clutch might be going, which is possible, but it doesn't slip at all under load.
OP when you are up to temp, do some hard pulls in 4th and 5th gear and see if your clutch slips. If your revs rise way faster than road speed, then your clutch may be done, although like I said mine is doing the same thing with no noticeable slipping under load.
OP, did you recently do anything involving your brakes?

Hello
Car is remaped and the clutch doesnt slip. I feel it more when its hot outside and when the car is hot enough. Its just like me, doesnt like high temps 
Not much time ago i replaced front brake discs, pads and brake fluid.

Interesting regarding the brake work. I ask because I saw another post on here today regarding weird clutch engagement and it got me thinking.
I also just had to change fluid and re-bleed the system because I disconnected the rears to swap axle beam bushing and my shudder has occurred since I did that swap, so I wonder if it could be caused by air in the system somewhere.
Hopefully others will chime in.

My first suspect are the inner CV joints.

Sounds like wheel-hop to me - if so, a new dogbone mount could solve it.

Would the inner CV's cause the shuddering/engine stumble only when starting from a stop and display no other symptoms? That is what mine is doing, and sounds like the OP is having a very similar/the same problem.
Last time I had a worn inner CV, it was vibrating/making noise under load in all gears. This feels much more like a clutch engagement/disengagement issue as it is only when starting from a stop (at least for me).

I can't speak for the OP, but I don't think mine is wheel hop. My tires aren't losing traction, its rather almost like the engine is about to stall. Or maybe I don't understand wheel hop.

It would help if we knew what car OP is working with, his listed cars says Passat, so just wanted to clarify!

Rear main seal getting oil on clutch friction disk perhaps for the jutter when cold. It goes away after a bit of operation.

That would certainly be annoying as I just changed the rear main seal like 30,000km ago.

Maybe.
But I had the same situation come up with my Jetta and from the bottom the dogbone looked a bit suspicious. I changed it and... problem gone. Hmmm....
After I pulled the old one out the difference in the condition of the rubber between old and new, and the amount of motion the old one was permitting, was REALLY obvious.

No, the classic inner CV joint failure presents as steering wheel shimmy when your foot is pressing on the go-pedal. As soon as you lift, the shimmy stops. And the shimmy is gear independent.
