From what you say this would be why VIDA sometimes can’t find the ECM – the weather at the moment certainly won’t help either!
I’ll pick up a new battery and continue my fault finding, often a good fresh battery is enough to drive out a load of electrical gremlins on its own.
Is it wise to stick with a Genuine Volvo battery or will it be happy with another decent quality brand?

yes you need at least 14v with the charger on for the communication to work reliably .
Regarding battery
get a quote from a dealer parts dept for the part , Excluding fitting . , they are very competitively priced . ...
