Turbo John. The EGR on my NCV3 2008 emits the tone. Normal for my Sprinter, for it always done it since new.

After the engine is shut down, the Tone emits for approximately seventy five seconds then stops with a final cycling click.

Not a problem. I think they all do it, don't know, maybe sonic cleaning itself.

My 2006 Sprinter has emitted the tone after shutoff for more than a day, I decided to unplug the EGR connection, and that stopped the tone, which did not start back up after reconnecting the connector.

It emits a high pitched tone with he engine running.. unless you put your finger on it whilst running…then it will stop

My wife says she refuses to sit out in the hood anymore with her finger on the EGR valve.

I was going to unplug the EGR harness wire from there to see if the noise would stop…..but I did not want to throw a code.

Any ideas what the noise is and because the EGR does not work like it was stock.

Maybe it is just the Sprinters with a GDE tune or?
John. I found this old post of yours. EGR on my 2005 Sprinter is emitting that same sound.
EGR valve is contantly powered up, even if the van is off. This resulted in a dead battery. Wondering if you ever found out why the EGR was making that continuous high pitched sound?
And what you did to resolve it.
Thank you
