Hi all
W211 e320cdi. Had a red warning light on now for a while so thought id buy some new batteries.
Bought a new 019 battery for the rear and a ytx14 for the front.
I have checked the polyfuse and it was good.
Checked the wiring from bcm to polyfuse and the both had continuity. Changed the aux battery relay as they were cheap.
Just today installed smaller battery at front and surprised to see the red battery light hasnt dissappeared.
Have I missed something.
As per instrument cluster ive got good voltage before and after start up.
Any help much appreciated
