I have these 3 codes 16891,17705,17544.
From searching on here it seems it could be a vacuum leak.
Is there other things that can cause these codes, like maf sensor or something else?
I replaced the kind of breather/valve thing at the back of the engine as there was a definite leak there.
Engine is a BFB 1.8t.
Tried spraying pipes but can't find a leak.
Also idle is a bit lumpy and when revved, it's slow to come back down to normal idle, even when engine is fully warmed up.
I also think it's heavier on petrol lately??
