3 years + old, done 26,000 km on the odometer. It look like this.

Any idea what should i do. Block Egr or restrict flow, Delete Cable or wait until it totally self blocking.

Cannot imagine what is in the intake manifold and inlet valve.

Get your injectors checked. Could be overfuelling.

If your DPF is having to regenerate too often then this can happen. Also get the EGR checked. It could be sticking.

Using EGR defeat devices such as blocking plates and Delete cables cause more problems as the EGR is used for boost control, and can cause EGT to rise.
