Blown Turbo?
I was on the track Friday through Sunday and half-way through Sunday at one of the corners, without any warning, when I accelerated, I got what felt like 50% power. It was said that there was a puff of smoke out the back. No codes. So pitted, restarted the car and accelerated towards pit out, but still got about 50% power. So I pulled into the paddock and shut it down for about 5-10 minutes. When I started it back up, lots of smoke (kinda blue like and very stinky - pretty sure there is oil being burned). I am guessing it's the turbo because when I set up BM3 to read boost (pre-throttle), no pressure builds (there is no hissing/whooshing sound like a blew a charge pipe or any other sign of intake/turbo air leak).
To add to my confusion, I checked the oil level via iDrive (kinda ridiculous there is no dipstick!!!!) and it said add a quart. So I did. Checked the oil level again and it said add a quart. I did not add a second. No one saw any sign of me burning anything prior. If I had a dipstick, I would not be concerned about some sensor not reading because I have eyes. It seems very unlikely that I burned through two quarts of oil without me or anyone else noticing. My car is 2.5 hours away at the track - had to find a ride home. Does anyone have any ideas other than the turbo? I am trying to figure out if I just bring it home and replace the turbo myself or if there is something more significant wrong and I should bring it to a shop (I am not interested in rebuilding the motor myself). Thoughts? Thanks in advance for any help provided! Last edited by M2guru; 10-09-2023 at 04:48 AM.. |

Good morning, really sorry to hear this - did you have any logs stored or pending (I saw you said no codes, but still) codes? Any noises?

Worst nightmare. Sorry to see this.
Mileage on the car? Had the turbo been touched at all from something like a DV or inlet upgrade? This isn’t something you see a lot of so it’s startling. |

Yeah this sounds like exactly what happened to my buddy when he blew his PS2...

I have some codes, but I think they're old - any way to see date on them with BM3? |

30k miles. Only touched the intercooler and charge pipe between the intake manifold and intercooler. Agreed - I am very surprised this has happened. I run conservative tunes - I was on a 91 octane tune running 93 octane. I was actually tempted right before this happened to go to the 93 tune. Glad I didn't or I would be blaming that change.

So it looks like the car was targeting for boost and can't get it according to the log. It seems like it's the turbo at this point. Anyone else see anything? The situation occurred right in the middle of the screenshot of the log that I shared above.

Doesn't look good, but I believe the turbo itself is interchangable from all the EWG models and is pretty cheap, the labor will be the worst part: Check Car-part.com , a EWG can be had for less than $200

Honestly I don’t remember exactly what happened but he had similar symptoms as you (blue smoke). Pure ended up taking responsibility for the incident and warrantied it

Did you check what your MAP sensor was reading?

I was using Boost Pre-Throttle for that information (not sure what sensor that comes from), but I am guessing that MAP is probably better for that information...? Probably, but I think I got the information I need to figure out my issue. Thanks for the suggestion! Boost Pre-Throttle will tell you if the CBV is working well I assume. At one point I am seeing Boost Pre-Thottle at 22.2 and MAP at 1.3, but it's a fraction of a second as I let off throttle.

Sorry to hear brother.
Almost same thing happened to me at the track. Injector failed instead. Had to leave the car for 5 days, drive back home for 4 hrs and come back to fix it. Do not drive the car, the turbo seals are done. |

This is the code I couldn't clear - 140011 (Misfire: Fuel injection deactivation)
It could be that an injector is stuck open or leaking. I wouldn't turn the car on again until that's eliminated from being the case. First step would be to check the spark plugs and in the worst case, you might even be able to smell it. Next step would be sending an oil sample for analysis, specifically fuel dilution. Let me know if you need help going through the tests and checking things with ISTA, I'm available most weekends.

So I had two quarts of oil left in the pan (four track days on the Redline oil and no daily driving), I have glitter in my oil (filter looked pretty good), and this:
