Hi,

i havet trouble with my MY 10 5,0L V8 the car got a new battery and sice then it wont start.
the cluster is dark and it seems it trys to start but goes dark again. the windows and the ac unit works. The interior lights and unlook doors wont work.

has anyone an idea?

Regards

You might need to do a system re-set, ideally with a diagnostic machine. There is the possibility that taking the leads off the battery and shorting the leads together (away from the battery) might work (referred to as a "hard reset" on here I think) but while that was done to my 2004 car when its battery failed in a remote location, I'm not expert enough to say whether that would work (and be safe) for yours, perhaps someone else who knows more can help. Only Range Rovers since 1988

i tried that the OBD port is also not operational. i tried to connect the laptop. id like to check the fuses in the glove box, but i cant open it

check the battery connections .. ... - .- -.

i did and cleaned them too. it seems that the car does not wake up. is there a part which is related to that?

with a fully charged battery you shouldn't have any starting problems..

i would check the battery voltage next.. ... - .- -.

its a complete new battery and i have coding charger plugged aswell. the windows are working on the left side not automatic, you have to hold the switch. the blower from the heating system runs at all stages. the cluster tries to start up and it gets light grey until shuts off again.

What happened in the lead-up to fitting the new battery?

a faulty old battery. i change it and drove the car to his parking spot disconnected the battery until i got back my painted part and know the does not do anything

It does sound like your not getting any switched power.
Have you tried locking the car with the key in the lock and unlocking it again ?

Somewhere in the manual it says where to place the key under the dash when it's battery is flat. That uses passive activation and may help.

I think the obd will only work in the accessory position, else the modules aren't woken up. Too many toys, not enough time

so you have checked the battery and its fully charged? sometimes new ones are faulty or not charged up..


if the above is ok then disconnect the battery , wait 30-40 minutes , re-connect and start the engine..as soon as the engine is running turn the steering wheel fully left and then fully right to set the steering parameters...

hopefully all will be well.. ... - .- -.

the battery has 13,7 Volt and the charger is on it.

i cant turn on the ignition if i push the button nothing happens.

What did you have painted? Is it something to which a lead is attached?

the car runs again. if have no clue what it was. i unplug 100 times the battery and sudenly the cluster was operational

same as yesterday i went down to the car, battery was connected and charged over night.
