Oxygen Sensor 2lt - 2001 CLK
Rear Cat. Oxygen Sensor connection plug cleaned and and put back, solved the problem. 5 months later,same problem back. I have been advised that it is the rear sensor connection that is the problem again.To solve the problem will require
the interior of the driver side taken out to trace the loom. 4 figure price quoted ££££. as there only 2 sensors in the system. 1 before, and 1 after the Cat. Only 2 Oxygen Sensors, according to main dealer.Question ? Is it possible to renew the
corroded electrical connections under the floor, without removing the loom and interior of the car.
