I don't know I have to change them, I hear of people who walk around with egt on the 950? with turbines gt series on the bushings, I didn't know this limit to 650?, I wonder, ? the first 1.9 with dpf that had normal gt1749v as the 159 1.9 jtdm which to regenerate and brought the dpf 650? as they were temp at the manifold??
I have to monitor, not to edit them, sorry :D
