E70 30d - Throttle Body Fault

[MrSweetE70]

Hi All,

ISTA+ states

00483D DDE: Throttle Actuator

I had a feeling it was fluffed because the engine shakes on shut off, my question is though, why do some Throttle Bodies (like my E90) have a spring which you can see move with the valve and some like what's on this E70 just have a cap..

My plan is to just chuck on the one from my E90 but I wanted to check what the differences are, realoem states the throttle body is also found on the E90.

This is the one on my E90 with the spring


And this is the capped off one which is on the E70
