"Total Recall" explained

I suppose this will happen after they finish replacing your EGR Valve/exhaust manifold assembly.

When they replaced your "SCR Reservoir Active Tank", you also got a fresh load of catalyst - correct? I read somewhere the catalyst alone cost $2,800!

Just wondering - did this EGR Valve/exhaust manifold combo start with the 2012MY X5s?

Thanks again.
Ok, now that I've had some time to really look into this, I believe I can shed some light on all this recall confusion. Why? I have two diesels (E90 and X5) and a friend also has an E90 diesel all of which cover this recall. In reality, it is actually THREE different recalls that each depend on engine production dates.

All three recall notices deal with the same exact subject: "Voluntary Emissions Recall Campaign 11E-A03: Check and/or Replace Emissions Monitoring Components"

In chronological order:

#1. SIB 18 02 12 covers - E70 and E90 with the M57Y engine produced from January 2008 to September 2009.

#2. SIB 18 03 12 covers - E70 and E90 with the M57Y engine produced from April 2009 to March 2010.

#3. SIB 11 04 12 covers - E70 and E90 with the M57Y engine produced from January 2010 to March 2011.

Recall #1 above requires the dealer to check the SCR part number. If the part number is NOT 18308509753 (E70) or 18308509750 (E90), the SCR catalyst will need to be replaced.

The next part of recall #1 deals with the "mixer." If your mixer has a "multiple fin" arrangement, then it will need to be replaced with P/N 18308513445 (E70) or P/N 18308512438 (E90) which are single fins. Single fins basically look like a jet turbine fins at the intake. Each fin is a solid single straight fin.

The last part of recall #1 is to inspect the EGR and replace it if it's the old style with (P/N 11 71 8 517 217 or P/N 11 71 8 512 526)

Recall #2 only deals with the mixer and EGR. This means that at some point in production, they started to install the new SCR part.

Recall #3 only deals with the EGR which means that at some point in production, they also started to use the new style mixer and only need to address the EGR.

Hope this helps.
