Euclid telescope engine (rebuild in KSP RSS?)

[Fragile-Engineering]

Hi space nerds!

a while ago I followed the launch of the Euclid telescope on a falcon 9 rocket. But what confused me is, that the target of the telescope is the L2 point (not LEO). So, how does the telescope get there!? I read the fact sheet. There it says the complete telescope's weight is 2 tons - including ca. 220 kg of propellant! I have read somewhere that you need around 4300 m/s of deltaV to get to the L2 point from LEO. My gut feeling was, that its not possible with the data from the fact sheet. So I rebuilt a probe with total mass of 2 tons and 220kg propellant in KSP/RO/RSS. And like expected: no matter which thruster I use, I get nowhere near 4300 m/s deltaV... (for example: with a 350 ISP thruster I get 354 m/s ...). 

So how do they get the probe to L2 with just 220kg of propellant!? Does anybody know the answer?

The F9 didn't launch Euclid to LEO, it injected it to an L2 transfer orbit. It has also launched payloads to GTO, L1 and lunar transfer orbits in the past

Hm, ok. I also thought of this possibility. But then the telescope still needs to slow down at L2. Therefore 900 m/s would be needed (occording to this thread here: orbital maneuver - What is the delta v required for insertion to sun-earth L2? - Space Exploration Stack Exchange)
Its closer, but still not possible when simulated in KSP/RSS. May the inaccuracy of the simulation be that big?

900 m/s are to stay actually at  L2, but most (all? I think) don't do that - they insert into a large halo orbit around it, like in the figure below, which has a free insertion but is dynamically unstable and requires monthly corrections in order to remain in it

Wow! Now it all makes sense! :-) Thank You very much for your effort!
