I have owned a few Japanese vehicles. And a good preventive maintenance item is cleaning their EGR valve.

Has anyone done this or have info on their NX or IS

 

That's a great question -- following...

When should this be taken care of and how often?

 

If you search Lexus OEM parts suppliers, you will only find an EGR valve listed for the hybrid model NX300 (with 2.5L non-turbocharged engine). The 2.0L turbo engine does not have one. Refer to post #8 in this message thread for additional information:

Oh, this is great to know as I have an ICE not hybrid, so I guess I needn't worry about having to care of this.

Thanks much for the info
