Air leaks?
Car: 1996 A8 4.2 auto
So im getting some **** poor mpg at the moment. Driving like an absolute OAP im getting 16.9mpg at best. Thats a mixture of 40 and 60 mph roads. I have noticed a split (read hole) in one of the crankcase breather pipes. Now im not getting any engine surging or cutting out like you would normally associate with an air leak so have ignored it. BUT it leads me to start thinking it is upsetting the mixture? Thoughts?
