GL350 bluetec EGT sensor
I have got engine light on GL350 with 160K km. The code is P2081 (Exhaust Temperature Sensor Circuit Intermittent).
Has anyone had such issue ? Can someone provide instructions on replacement of this sensor. This sensor is on turbo exhaust side next towards passenger side right near firewall. Very hard to get any leverage on.
This video show the sensor and potential fix, but i could not break it open and slipped once so dont want to try again and cause grind on thread .

The part is under emission modification warranty. If your car received the modification from the dealer, they will fix it for free. I got P2084 and the same EGT sensor went bad and the dealership replaced it.
