This is a replacement auxiliary battery for MB E-Class 2015. "Auxil...iary Battery Malfunction" kept being displayed. Owner can replace so bought this. At first, same result as with original battery.But this morning, after long journey yesterday, I was getting intermittent 100% functionality ie. ECO light on and "P" sign displayed meaning I can depress brake pedal and "hold" whilst engine cuts out. Depressing the accelerator then restarts the engine. So, I think with charging, this battery might work ok. Difficult issue to resolve.

I was receiving message "auxillary battery malfunction" o...n the display. To replace battery at main dealer, which also includes diagnostics and fitting would have been close to £225. This battery cost less than £80, is a genuine mercedes replacement part and therefore does not infringe any warranty, Took me less than 15mins to replace. Good product and with warranty.
