I have a 2001 A6 2.7T with steptronic. every time I start the car it smells like something is burning about 2-3 minutes after I start driving the car. I always warm it up for at least 4-5 minutes. I just changed the oil about 1000 miles ago, put in 5w30 cynthetic, and the burning smell is getting worse actually. My car's got around 63k miles, I'm wondering if this may have anything to do with the timing belt? I know it has to be changed by 75k miles...

Has anyone had the same problem before? Can anyone help me diagnose this before I go to my mechanic - I don't wanna pay for stuff that's not broken !!!

Please help me out

 

BTW the smell is coming from under the hood, but I smell it inside the car too through the ventilation system... what could this be? are there things I could check while I'm in my driveway to see what may be wrong? I doubt its oil dripping anywhere on the manifold or anything - my mechanic would have seen it when he changed the oil...

 

standard checks are rubber belts next is egg smell "catalyst-o2 sensor"
