If the dpf is showing as constantly full ,It would do with a blast down the motorway to see if it will do a regen itself,The problem with EGR is that short /town driving doesn’t help them…I don’t know but do merc give you a regen switch ,where the driver can carry out a static regen when required …■■
Yes. It looks like this. (sorry for the messyness. I’m about to start polishing!)
