Hi everyone

I bought my 8 a few months ago and serviced the engine abut 3 weeks ago. About a week after the service my car started to smoke more and more by the day. At first it was just a little bit after a drove it to redline a few time and now it smokes around every corner. It doesn't smoke continuously but when the engines rpm goes over 6k and I let of the throttle completely without changing gear and get back on it...the cars behind me completely disappear in the huge cloud of blue smoke. In about 100km it used 2L of engine oil!!!
I know this ain't right and I have already replaced my Oil Metering Pump but the problem didn't go away.

Any advise...Please help?

What was the service performed?

It sounds like you're sucking oil into the intake, I would clean the intake thoroughly and if it is indeed oily, I would get a compression test.

Sucking oil into the intake is a common sign of blowby, which is a sign of poor compression. You can solve the immediate problem by installing a catch can, but that compression isn't coming back, so make your plans accordingly.

If the intake is not oily, then oil is getting in there some other way, all of which would require a rebuild.

Also while this is happening, your catalytic converter is getting clogged with oil, and could clog completely, ruining it. I'd avoid high rpm driving, or any driving in at all, until the smoke is resolved.

The OMP did not need to be changed.

Aside from Loki's doom and gloom, you could be smoking as a result of over-filling the engine oil, or as a result of using a short funnel, which allows oil to dribble into certain vacuum lines. The correct oil level is about 1/8" below the top tot on the dipstick. You do not need to fill it all the way up. Anywhere between the bottom and top dots is fine. If it is due to oil in the vacuum lines, it will clear up on its own, but it sounds like you have too much smoke for it to be that.

So pull your airbox and check it and the rest of the intake tract for oil. Clean everything, including the MAF sensor, reassemble, and see how things go with a correct level of oil in the pan. If that doesn't fix it, see Loki's doom and gloom above.

Yeah, check the easy thing first, which is the oil level.

You'd be surprised how incompetent people are at changing oil. Some shops will only follow the book and overfill since they didn't drain out as much, while whenever I change oil, I only pour in 2 L, and then check the dipstick and see how much more I need and add accordingly.

And yeah, buy a long neck funnel.

Make sure you're checking your oil level correctly and the same each time.

Warm the engine up to operating temperature.
Park on a level surface.
Turn the engine off.
Wait 5 minutes before pulling the dipstick.

I did an oil change and overfilled the oil but I didn't realize it until 3 weeks later an an autocross. I just wasn't hanging out at high RPM long enough and doing high-G turns on the street... It looked like a Bond movie half way through my first run. Crap tons of oil in the intake. Had to clean it and the MAF out after draining some oil.
