V12 battery partially charged ADblue 31%

[Paddy86]

First time having a Mercedes Benz I was just wondering if I need to buy a new battery or does the car just need a good run out.
And it says on app my ADblue 31% this is okie for now???
Thank you

Sounds like you have just purchased the car.

As a result I’d put a new Bosch S5 or Varta silver battery of the correct spec on, then you know it’s a good one. If you don’t use it for long runs often consider a charger like a Nocco or Ctek to maintain it.

Adblue - I’d drain the existing tank (I use a sucker pump), fill it with fresh adblue and bottle of forte anti crystallisation additive.

Then take it a for a nice run.

The battery terminal may have a date on it ….it might be new ?

May be, I was just thinking it’s likely the case of a used car where it’s best to assume everything has been skimped on and batteries run down and jumped to get the car out the door.

99% of the motoring world don’t have your attention to detail buddy (but you are probably right )

If he's going by the Mercedes Me app it's notorious for saying the battery is partially charged or worse when there's nothing wrong with it.
He needs to check the voltage himself and not rely on the app.
