2012 C63 O2 Sensor location
Hi Guys, so the EML lit up after a spirited drive. Checked the diagnostics and its an o2 sensor.
Access to the pre cat o2 sensors is ridiculously cramped. Anybody changed these before? Any tips on locating and removing post cat sensors?
Cheers

Found a pic showing all 4 locations
I had the car in for a service and they quoted over £500 to replace the sensor.
Bit steep, considering a bosch sensor is ~£100.
I was taking the car to Goodwood so needed it sorting, managed a 25% discount.
Given the location of the sensors, accessible from under the car after you remove the skid panels, its best done on a lift or ramp. Theres no place to jack and place axle stands safely, which would have made it a relatively cheap fix.
