2008 E320 Bluetec O2 Sensor.
 

Hello!!

I recently (April) purchased a 2008 E320 bluetec with 91K miles, great car and I had nothing but great efficiency and performance, last Friday I got the CEL light with the code P2A01 Bank 1 O2 sensor..


Here is the question, I would like to try and change this my self, but there is very little clearance from the side wall and the engine.

Any ideas what the best way to tackle this job?

thanks

Cant help with the replacement. Have yet to even crawl under mine.

There was a repalcement campaign. Ref #2009020001 dated 03/2009.

Replace O2 sensor upstream of cat and update ECU software. 07-09 models/7,403 vehicles affected.

PM me your email and I'll send it to you if you can't find it online.
