So a few months back I got the CEL and came up with these two codes which are for Bank2 sensor 1 O2 sensor. Last week I had a new Bosch supposedly OEM O2 installed and the codes reset. This morning the CEL came back with the same codes. Now I looked at the sensor (bank2 is left side/ driver right?) and it seems part of the rubber around the sensor is making contact with the firewall aluminum heat shield. Wondering if that's not supposed to be as the passenger side is not and possibly the heat shield is melting the wiring.

Can someone possibly with a preface lift C350 or even a C300 go to their car, open the hood and take a picture of their Driver side pre-cat O2 sensor. I want to see if their is making contact with the heat shield. If you open the hood all the way in the service position you can see it standing by the tire looking down.

I'm also open to other suggestions.

Thanks
