P0471 and P0472 W212 error code

[milan11]

Hi I am new here, I have 2 error codes P0471 and P0472 coming up on my cheap scanner which shows it is the exhaust pressure sensor. Car is a 2009 W212 E350. I have been searching online to find out which sensor needs replacing and where it located but having no luck.

Any help would be appreciated

Regards

I managed to get the part from MB and changed it today, very easy job. So far the EML had not come back on, so hopefully fixed for £58.
