I'm getting the above fault code on my E320 CDi Inline 6.

Symptoms are car going into limp mode if I exceed 3000 revs. Clears if I stop and restart.

The fault code is described thus on my reader:

"EGR Vacuum regulator solenoid circuit fault"

As my EGR is electronic could this relate to the DPF pressure sensor mounted next to the ATF dipstick which is apparently pressure regulated in that it has two hoses attached?
