Hey MB Fams.

So recently I've run into an issue with my W204 C220 CDI.
At about 21km/h I get an error message saying that my ESP, ABS power steering not available and tyre pressure sensor inoperable.
I have had this issue before, my mechanic said it's the battery. He told me the reason as to why that happens. I replaced the battery and I didn't have that problem again.
I am now experiencing that again. Local battery place (For the South Africans here it's Battery Center) have checked the battery, (apparently it's fine) there's charge going to the battery at 13.9-14V. So alternator is fine.
What else could be causing this problem???
I will be checking another Battery Center (Battery is under warranty, which is why I'm suspicious as to why they don't want to swap it out for a trial)
