The original TCA 700Y part is no longer made. The replacement has the
order of the legs reversed so it must be installed upside down. There is
a metal spacer installed on the heatsink part of the new reversed part
so you can install it backwards and still screw it down as VW intended.
That is, places selling the new part as a replacement have a modified
new part to better substitute for the old part. At least this is my
understanding.
