Today is discovered that a former owner of my car put newer model drosselklappe on it.
Wiring brown/green are put together, car runs oke for 8 years.
I have a older model for spare, shall i make the car Original or leave it like it is?





Edit:
The pink hose on the picture is connected on the drosselklappegehause....it seems to go underneith the dash but i cannot find it beqause of all the wiring.
Does anybody know what this hose is for?

I took it out complete, i found one number: 051 133 154A



Can anybody tell me which hoses on which connection belongs?



The yellow connetion is closed with some metall.....



Off course another question : Can i adjust the bolt in the purple circle?
The reason i ask is that my car has a to high leerlauf ,the adjuster screw is complete at the end.
I noticed that the small klappe is not closing compete, there is shining licht trough if i look in the sun or with a lamp.

Edit: Found this, looks like mine.

No, i only adjusted the screw
Here is my situation of the vaccuum.

Thank you, i am going to do this with a friend of mine, first i am going to put in a bigger LMM (53.1mm) and today i bought a new drosselklappe.

Thank you for the advice but no thanks Off course ive read all these modifications on your website but for now i put it on and enjoy it.

I did that beqause the website says that the drosselklappe is 52mm and so bigger as the LMM.
That was the idea

Yes i understand, i did such modifications on my dirtbikes few years ago, the less obstacles the better the flow, only different thing was that i did not polisch the air inlet, i was told that you have better air flow if you leave it a bit scratchy, the outlet should be as smooth as possible.
