Eccentric Shaft Sensor

[talljames]

Hi all, i have been reading about the eccentric shaft sensor of late and I am thinking this may be a cause of an issue. I have a 2005 X5 E53 4.4i sport v8 engine. I am asking because I am getting the check engine light and the “DME Fuel mixture adaptation, idling, per time unit” 29E7/present code error after I drill down from the Engine-DDE Diesal Electronics DDE3.0 Fault code. While scanning the web I found one user got rid of the codes by smoke detection and found the eccentric shaft sensor seal was leaking. I assume this sensor is at the rear of my engine and hard to get to?

cheers
