Hi guys, Done a compression test on my s3 on wednesday night after it failed its m.o.t on emissions. The result i got were 13,10,11,13. Ive made a search and cant find out wat they should be. Went to buy a Hayes manual but it didnt cover the s3. The car smokes a lot when its first started up but on the go it doesnt seem to smoke any more than most cars. Is there a chance it could be the turbo? Im not very clued up on engines so i dont want to spend on something i dont have to. When the car is started from cold you can smell oil burning! Any help would be very much appreciated, thanks for reading.
