help needed with audi a3 1.6 sport URGENT

[matt46cars]

Hi 

bought a 1999 audi a3 1.6 sport petrol

 

when i got the car did not notice these things until now but need your help on this

 

the car is using alot of oil, dont know how much but mayeb few litres a month roughly

the car is fine when cold but when it heats up to around 90 it has a rough idle where it will go from maybe 600rpm to 1000rpm constantly

also car is doing a really bad mpg maybe 80 mile to £20 

 

i have noticed what looks like a pipe to be missing and the source of an air leak or oil leak

i took these pictures , as you can see 2 holes are being covered with tape , can anyone show me what

item is missing and weather or not this will solve any problems?

or does anyone know of any other solutions

 

thanks

Sounds like it could be sucking in air were it shouldn't  be

You have a breather hose missing for the PCV.  Go buy a new hose, it should not cost the earth and it just clips on.  This should help stabilise your rough idle problem (providing there is no other underlying fault).  It may hep your fuel consumption slightly but if you are seriously using a few litres of oil per month you car either has a serious oil leak, or frankly, your engine has had it!
