Hi all,
Can anyone can help on this one?
My 2009 A4, 2.0T blows out a puff of dry black smoke on morning start ups, and thereafter ONLY when I change down a gear...or accelerate hard on the higher gears.
There's no oil - just dry black soot/smoke, and usually just a puff.
There is no powder visibly blowing when the car is driving at a consistent speed on any gear.
1. Mileage is 167000km
2. Oil consumption is aprox 500ml every 300-400 km's
Any advice please?
