Yes indeed it could! -- what battery did you fit? Current: 2011 FFRR Vogue SE 4.4 TDV8

I fitted a big AGM Varta battery..

Its not very old, i just wonder at what voltage does the car say no to the fbh working?

i wonder if that specific range of not working volatge is quite easy to get to even with a good battery once you have played with the car a little.. Regards

I have something approaching the same issue -- I suspect battery voltage -- I haven't had chance to look at what the voltage threshold is (or even if it can be found and then altered)

Simple solution is to have it on a trickle charger, others may be more time consuming to work out  Current: 2011 FFRR Vogue SE 4.4 TDV8

They certainly are fickle things, i know it works ok because she always fires up with the engine, but i suspect the threshold for battery volatge is too conservative.

Turned mine on again at 5:30 and worked fine.

So I must have put the battery under the threshold yesterday.

Seems like not a lot can put you under the threshold of weather it turns on or not. Regards

Taken from the FBH manual.



However, I feel quite sceptical about this being true to the working of the FBH, 10.5 seems to low to me. I wouldn't expect a battery with 10.5 volts to be able to start a L322. So I have always wondered if this is incorrect, or maybe I read the manual wrong.
