Correct Battery

[Timol27]

Hi guys

 

my head is melting with this issue.

had my x260 battery replaced and I’m sure that the start stop has stopped working. Tested the voltage and says 12.3v off and 14.8 running. Also it’s an 80ah battery.

mechanic says it’s fine but I see that a lot are  saying it should be 12.6v and at least 95ah for the stop start to work properly.

 

someone please put me out of my misery!!

First of all the car won't know it's only an 80Ah battery so that isn't the cause of the Start-Stop not working. However, if you do get the start-stop working, a lower power battery will be more likely to go flat in traffic. It's obviously not fully charged as it should be 12.6-12.7V for fully charged.

I would insist a 95Ah battery is fitted as per spec (assuming you have found a reliable source to confirm that) and then you probably need to reset the start-stop as well as other systems.

Hopefully you can find the relevant information there to do it.
