Fred. Check your other post reference this.

 

thanks for the link...
Are you saying sify that this pump is the correct one for the Xfire/SLK32/C32???

 

Check the codes and before spending any money on a new pump you need to make sure that your MAF sensor is reading the small amount of flow created by this blower. Buy some MAF cleaner and give that a try first. The blower is coming on when the engine is cold?

 

The air is pumped into the exhaust not the intake.

 

According to my research of online retailers and other threads, the Bosch # is the one that cross-references the M/B #. Prices very widely up to $1100 on Pelican Parts for the OEM M/B part. This M/B # seems to also be one that is widely used on most M/B models.

Here's another ebay listing for a cheaper brand (with no p/n) and the 288 different models it's compatable with...including XFires!

Check through this thread. Other fixes involved a corroded ground and a clogged check valve that both fixed the problem.
