P0426 Fault Code

[Nytram]

Hi all
I am hoping someone can help me, I have a 2012 cls350 and recently EML has come on, i have used an OBD diagnostic tool and it brings up the code P0426 Powertrain Catalyst Temperature Sensor Range/ Performance (Bank1 ) Code. I am looking for 2 things , 1. An approx cost before i go to a garage. and 2. A reputable garage in the South Wales area. the car is reasonably new to me ( bought 3months ago ) and with lockdowns and restrictions not had chance to find a decent garage as of yet. Any help on this would be very much appreciated.

Well the code is telling you it is a Cat sensor,now these can be taken out and cleaned before you get into the realms of buying and fitting a new sensor,you need to get it to a MB indy with Star,because this can snowball into serious money without knowing what has gone wrong.
