so ive been having a few issues with my petrol (none turbo) 2001 a3, let me list the problems;
1) low oil - had a full service about 5 months ago and had to put nearly a full 5l of oil in the engine yesterday...bit worried by this
2) had to top up coolant as it was at minimum levels, its been topped up two to three times since it was last serviced...again worrying
3)High fuel consumption low power, getting about 80 miles out of 20£ worth of fuel (15l) which isn't great
4) when I put air con on, im getting very noticeable judder through the steering wheel when idle and acceleration and responsiveness of the engine just disappears.
I cannot find any oil or coolant on the floor under the car so if there is a leak it must be a small one. ive not had the car scanned yet as it goes to the garage on Tuesday.
any ideas as to what the issue may be would be appreciated, never had these issues for the first six months of ownership, just been getting progressively worse over the past 5 months.
