I was ready to change the Golw Plug relay on my 2005 E320 CDI US and ordered the correct one so I though from online. The module I received was A 648 900 00 00 Q 01 (51 299 029 12V). This is one with the 6 pin plug and the brass stud connection. After searching over and over for this module, The only item I can find is a module mounted under the intake manifold above the starter (648 153 02 79) this one has a spade connector rather than the brass stud.
I searched all over and am finding conflicting information. Is there two different relays/controllers on the
car
. Did I get the wrong one from the parts house. They claim it is correct and the item with the spade connection is the pre glow relay.
Help is needed please.
