Hello all,
first of all let me thank you all for the interest and the support.
i have tried few of the suggestion above but more in detail:
@Herbie: i followed you advice this week, but just extended for 2 or 3 extra day. Lexus dealer has replaced few times the battery with a new Genuine Toyota one and never fixed the issue, after couple of days (never more that 15 days) is always the same story and i have the feeling that doesn’t matter how much i ask then, they never check where this absorption comes from, they check only the computer which tells all good so for them is all good. Unfortunately I don’t have garage or drive way as i live in city center.
@Romasato: i do have a solar collector, don’t recall the brand, but was UK first choice and, as confirmed from @ColinBarber just keeps a bit of charge if it’s a fully sunny day but doesn’t help charging at all, not even to start hybrid system.
this is the reason why i am getting a bit exhausted of this situation especially because i have a little kid and every time i am rushing somewhere because of him, i need to jumpstart the car and you can imagine my wife’s comments about it.
thank you and have a great weekend.
