	Some of what follows is outdated now. BMW seemed to have opted to bring the "lag-fix" for newer (i.e. post-09/07 built) MSD80 cars as default to the newest software release, now current is at least [http://www.bmwtis.com/tsb/attachments/B090707_ISTAP_Version_Data_Status.pdf ISTA/P 2.40.2], but this is not so. It first seemed like the "wastegate retrofit" option has disappeared from the ISTA/P menus from v33.1 on - even for MSD80 cars that previously needed to have it selected after the update, but it still has to be selected specifically one time. The setting is applied once to the car itself and stays there for any subsequent update - it just does not have to be re-selected again (and it cannot, once it has been applied).

	This makes life a whole lot easier for customers and dealers, no bells and whistles anymore... just get an update from v32.1 upwards, if your car's build date is pre-10/07, request the "wastegate retrofit" and you'll be set, at least lag-wise!

	If your car got a software update for any reason (also non-ECU-related) after 03/08, it may show this lag. There is no hidden menu or something where the software version can be displayed, BTW.

	This "turbo lag" was initially denied when first reported and only after a long time of continuing pressure, BMW acklowledged that there was a problem which first lead to a [http://www.autoblog.com/2008/11/18/bmw-finally-acknowledges-turbo-lag-will-update-software/ press statement] and in January 2009, to a release of a new software called ISTA/P 2.32.1, which is referenced in [http://www.bmwtis.com/tsb/bulletins/bulletin_graphic_temp/B111307g.htm SIB 111307]. Now-current is at least ISTA/P 2.33, which you can see here.

The initial problem

Zeile 59:		Zeile 59:
	BMW used flawed wastegate actuator rods in N54 cars (x35i) with build dates up to 09/07. Well, actually, they said once that these have been fitted up to January 17th, 2008. Those rods elongated over time so that after a little wear, the wastegates did not close tightly any more, which gives a ticking, rattling or clanking sound at idle.

Those rods elongated over time so that after a little wear, the wastegates did not close tightly any more, which gives a ticking, rattling or clanking sound at idle.

	In order to avoid costly replacements, BMW brought up a "rattle-fix" in software with Progman v29.2 in 03/08. This software fix made the wastegate become open at idle. Only when you depressed throttle, the wastegates were closed and the resulting delay to build thrust could be noticed as lag.

	A: Have your dealer look at them. He has to measure the thickness of the rods in order to find out (old ones are 6mm diameter, new ones 8mm). There is no VIN-based database on that. However, if your wastegates don't rattle, you are not entitled to a preventive hardware replacement anyway - and since May 2009, you aren't even if they do.		A: Have your dealer look at them.
