I scanned the IPS on my E320, the readings are about the same but the E320 range for this sensor is less than 500 hpa vs my S55 shows the range should be less than 0. Kinda strange but o well. I think I'll have to buy a smoke machine now.

Smoke machine is pushing smoke out the egr vent. Is this normal when no vacuum is applied to the egr?

I put some duct tape over the 3 ports. The CEL went off after 3 short drives with all monitors set. A new EGR should be the final solution.
