Fighting the CPS issue on my 2006 now. Generic replacement was a no-go, which seems common knowledge on this forum, so I've got a bosch on the way.
I suspect that the wire underneath the boot at the CPS could also be damaged, the boot itself is cracked where molded to the wire.
Amazon has some plugs that look to fit but I suspect the leads are too short and would have to be spliced.
I couldn't find the part numbers on this site but you can replace the cps wire leads and connector directly to the ECU pins using the following:

Mercedes Crankshaft Position Sensor Connector 1685453028
Mercedes Electrical Contact 0005403805

 

The connector has been suspected as the cause of CPS codes without any definitive proof. Thanks for the info!

PS I just order parts from eEuroparts myself and it took them a long time to get the order to me, like two weeks, but the parts did arrive and I have what I required.

 

Same story from europarts on my end. I got a partial shipment on time but the connector itself is still in route. Will by nice to have the xf back so no more riding in the rain.

 

The boot on my Graphite was cracked, didn't matter, the car ran fine once I put a Bosch sensor in.

In fact, my boot was so brittle, the locking tab broke off when I removed it from the old sensor.
I used a dab of RTV to make the connector stay on the sensor.

 

Yet one more piece of evidence shoving me towards buying catless down-pipes.

 

If you want a connector with pig tail wiring, $15.99
