EGR Pipe '92 400E - PeachParts Mercedes-Benz Forum

Where did this diagnosis come from - that you needed to clean your 119 motor EGR pipe to pass emissions? The EPC shows an "exhaust line" from the "intake manifold upper part to the intake manifold lower part" but I've never heard of such a thing getting clogged and causing a problem.

It pops up on this forum occasionally. I believe there is an updated part which resolves or mitigates the clogging issue.

I was asking more about the basis for the diagnosis - are you getting an EGR fault? has the EGR valve been tested? What information led to the diagnosis?
