Need help with the above codes if possible,

 

getting an issue with my 68 plate Octavia estate. When I put it into reverse I get several warnings coming up about park assist and manoeuvre braking fault. 
 

B189CF0 - Crash Shut-off - Active is what the code reads

B1802F1 - Nv- energy management - alarm triggered. Is what the top one says, I’m going to change the 12V batter tomorrow. 
 

anyone any experience on these codes? 
many help would be much appreciated. Thank you.

If you are changing the 12V car battery because you have let it get in a too low state of charge and/or state of health then this can throw up all sorts of codes and warnings.

 

If changing battery it'll need to be a battery in a good state of charge and health (obvious I know but in my experience I've been told a battery "is good" when it isn't, more than once) or if fitting a brand new battery then be (almost) exactly like for like or it'd be best to 'code' the new battery in.

 

With a (properly) good battery fitted clear the error codes and see if they return.

 

Is there a reason you couldn't recharge your existing battery with an appropriate battery charger (following the car's 'Owner's Manual' advice on charging rates).

 

Let us know how you get on.
