Thanks for reply.
Yes you're right, i do have the other air part intake. It was so old I could not make out if it was the missing part or not. Will replace just in case.
What is the reason the GTI did not have the Pierburg carb?
I know the GTI was 16v and injection but what else made it special?
Also, what fluid is used in the green round tank?
Is that your Golf in your sig picture? It looks great, the original look is something I want to aim for. Looks very tidy.
