First of all had the A4 Quattro 2.8 for three weeks it is a blast to drive
It snowed and iced here in Raleigh nc last night and there are only 4 plows in the county yes only 4. So roads are a mess. Too the Quattro out and man it was great in the snow and ice no slipping at all. First all wheel drive car I have ever had .
Now for the issue slight oil smell in the cabin when you driving the car. No leaks underneath . The engine is covered up with the Black engine guards .I guess Ill take it off and take a look. My guess is the valve cover gasket probably has a little leak. But I thought I would through it out to the group with much more experience than me.
Also low beam headlights seem very dim any suggestions?

Thanks Boss

 

I don't have a solution to your issue, but you might find more members willing and able to help if you posted in the A4 subforum rather than the A5 one. Just a thought.
