part number listed at Max BMW is still: 16117704799
Which is the P/N they gave me in 2011 near the end of my warranty period on my 2009 ...
(and this replacement is starting to crack...)
You get a 5-year warranty from date of install
Is that a special Canada thing?
Here in USA I think the best we can hope for is either 5-years from date of mfg (since it is an emissions related component),
or two years from date of installation of a replacement ....
