Need specific part name and help

So just had my WK looked at today regarding a 'service 4wd' notice. The dealer says it's a 4wd sensor located in my rear diff thats going bad. Being at work, I couldn't have him go into details. They want about $400 to fix it. Sucky part is, it's not covered under my powertrain warranty.

So, what I'm wondering is, what is this sensor called specifically and/or part number? Is it just better to let a mechanic do it? Any one else replace this?

*edit* So I may have found the name: rear electronic limited slip differential pressure solenoid (sensor???)
*edit* Should this be covered under my powertrain warranty?

Yes the elsd differential pressure solenoid could cause the service 4wd . There would have been a specific DTC code though . did they tell you what it was? did they erase the code first and see if it came back ? I've read people on here have changed the solenoid themselves . From reading the service manual i suspect the $400 fee is almost all parts because it looks like a 20 min job to change . here is the exact description from the service manual on how to replace .
With solenoid disconnected resistance across the solenoid should be 13.5 to 14.5 ohms at 25°Celsius (77° Fahrenheit).
To replace the solenoid diconnect wire connector then squeeze the retension clip and pull solenoid up.
