Hi, i recently made an oil/filter change on my 2005 A4 Quattro 3.0 V6 and since that time, occasionally when i stop at a red light i smell an odor of burn oil in the car, generaly for 5 to 10 seconds.
There's no oil drop on my garage floor either than on the pan bolt or near the filter gasket. I'm really worry about that, does anybody got that issue ?

Thanks

 

Best educated guess would be valve cover gaskets. It's a common issue among a variety of Audi engines.
