1.4 D4d overheating issue

[Adam Cotter]

I have a 2014 1.4 D4d corolla with 100000kms on it. It is overheating only on inclines when engine is under load but when you ease off the pedal it cools right back down again. I've changed thermostat, temp sensor, tried different rad, by passed water cooled egr, had engine pressure tested and waterpump is working as it should. I'm out of options. Its controllable but very annoying for an engine that's meant to be bulletproof with such low mileage aswell. Did anyone else have a problem similar to this? Thanks.

Check pressure on dpf may be obstructed...

Thanks. Was thinking egr or dpf blocked but engine light would surely came up and you'd notice somethings not right with the power as in she wouldn't be breathing properly.
