2012 F10 528i blue smoke

I was wondering if anyone else is getting a puff and sometimes quite a large amount of blue smoke on start up? I have 44k miles on the car.

Its concerning me as the tail pipes are heavily sooted also. I know the DI does create some soot but I worried about a cylinder head problem. I called the dealer waiting for a call back. I don't think it should puff any smoke on start my previous and my wife's current 6 cylinder BMW's don't smoke.

If you are not burning oil, then it could be an injector issue.

Buddy of mine's 12 528i just came back from the dealer for smoke on first start up. He was at about 53,000 miles. Turns out it was the turbo oil lines. They goodwill warrantied it along with performing the thermostat recall.

I hope you're able to resolve your oil problem.

Mein Auto: 535i
The electronic oil measurement system is rigged. On my 535i, the difference between MIN and MAX is supposed to be one quart. Right before I changed oil, it said I was down 1/4 of a quart (75% from MIN to MAX). When I changed oil, I shorted the fill by one quart, got the car up to operating temperature, and did another measurement. It said I was down 1/4 of a quart. So, what BMW says is 1/4 quart of oil consumption is really one quart of oil consumption.

Start-up smokes come from two places: valve guide seals, and turbochargers. Also, just a few drops of oil can create a cloud of smoke when the engine, and the catalytic converters are cold. I had an twelve year old, 150k mile beater that would occasionally put out a cloud of start-up smoke. But, it burned very little oil.

You need to document this with a video, and possibly a witness's affidavit: date, location, time, mileage, cold engine, time since last shut-down, etc., and take the car in and report this before the warranty runs out. A problem reported during the warranty period, but not properly repaired is still covered after the warranty expires.
