I have a W211 2008 E350 RWD Sedan. I need to replace the brake wear indicator cable on the right rear wheel. I am not referring to the sensor, but the cable that the sensor plugs into that runs up behind the wheel well and plugs in somewhere up there with a right angle plug. Before I go taking things apart, is the plug-in point accessible from the wheel well, and what is the best way to get the necessary access behind the inner wheel well? Thank you.
