^ yup im having the exact same setup. March 07 production MSD80 no updaters ever.
Hopefully someone with a 3/08+ or someone who knows they have 29.2+/v81 can chime in.

So, with v29.2 all cars up to 03/08 have lag. The distinction is made so that build dates 09/07 to 03/08 can have the no-lag software per default from January 2009 on, whereas pre-09/07 cars will only get that software on request for less lag (but you "have to understand" that this can cause rattle). |

And basically the MSD81 cars that came with 29.2+ are just plain F'd....or the new v32 when they get updated will fix them? Im really confused? I dont really want to make my purchase based on build date but so far it sounds like the 09/07-03/08 production dates are the cars I want to search for, LOL. That or a pre 09-07 with fixed actuators? |

Ok, so we've basically locked down that you guys who have pre 29.2 and have never gotten an update are consistently showing 1" of wear on the rear rod, then upon starting, the wear dissapears. Now we need some post 29.2 updated victims.
I'll volunteer, when I get home in a bit. Could one of you guys be trouble to post a picture of your rod (HA, sorry) with the car started, so we can get a visual? Hell, I don't even know where exactly to look. If I remember correctly, it's about middle of the engine length-wise, down the bottom, on the passenger side? |

So when the car is off, you can see the wear mark on the ROD, the reason it goes away is because the Actuator has pulled it into itself when the car is started in order to close the wastegate, which creates the wear mark in the first place. Here is something that may help, use Mr.5 first set of pictures to see where you are looking, you will see the rear turbo wastegate(only one there) and the ROD, cant miss it, just get a flash light. http://www.e90post.com/forums/showthread.php?t=132037

Let's not forget that even 29.2 performs better right after a cold start. So to have a meaningful poll, we might have to report rod results for BOTH actuators:
1. Before start 2. After start 3. 10 minutes later If I start my car and just let it idle, then after about 10 minutes, it lets out this big loud fart and drops the exhaust note about five whole steps. I wonder if that is related... |

Anyways... I just did this (w/o taking pics) and I do see the wastegate rod move about 3/4", although it's kind of hard to discern as my engine bay is really clean still. I did check the clips around the vacuum tubes (heh...) and one was tighter than I think it should be. I loosened it up, as well as slightly rearranged the tubes coming out of the things right behind the headlight (they were slightly kinked, but not very much). We'll see how she drives tonight.

If you're referring to my picture, I posted it because ezatnova didn't know where to find his rod! So I showed him mine.

If ezatnova hadn't made that rod reference... I'll have to go back and take a pic of mine for completeness sake... and think of some way to measure it somehow. See how long my rod is...

My car seems to be the same in cold or warm when talking of wastegate being closed during idle. P.s. where are all the 29.2 guys, give us some feedback. Only way this might not work is if bmw isnt opening or closing both turbos wastegates together, or leaving one open and one close/ vice versa. More 29.2 input please

I fully agree with meyer. They are making an announcement but not andmitting a defect. That would open a wastegate...I mean floodgate of problems for them.
I am curious how they will be addressing the mechanical problems that are sure to come up after the cars are flashed back. Or maybe they have figured out that by waiting until January most of the cars mechaincal issues will happen after the warranty runs out on the build dates that will be reflashed. One can never be sure with BVMW, they are a tricky beast, wily and cunning, much like Wile E. Coyote....Suuuuper Genius

I dont think they are going to be as accomodating as we would like. They have already made it clear that you have to have another problem to get the reflash. Then I wonder what other hoops we will have t o jump through to get this. Do you think Dinan people will be able to get it as a warranty issue or will they probably have to pay?
I get the feeling we shouldnt put the KY away just yet.(pardon my crudeness)

My car is a 10/07 build, no software update since purchase. Like the rest of you, the rod on the wastegate shows the 1" wear when the car is stopped, and then it disappears (assume it is being pulled in) after I start the car.
Is this actually any different than a 29.2 car?

Now the big benefit will be if bmw is keeping both open with this new software, in which we will be able to tell right away if u have a 29.2+ software, or if they are just changing one turbo wastegate position with the new program.
