V50 Electrics : - No electrics to door/dash with error codes

Lvolvov50 · Apr 10th, 2024, 21:08

Hi all, i am having a nightmare with my 2011 v50 lately so hoping for some help. I have the lux model, so i have a fob that lives in the car to start it and buttons on the outside of the doors to open when im near. The past 2 weeks alot has happened! I locked the car as normal, next time i went to go out it wouldnt unlock with the fob key, started the car with the fob key as the plastic fob wouldnt start it as it said key not found, with this the door lock/unlock button didnt work, nor the windows. The light that locks the back windows wasnt on either. Now as im driving 'brake failure stop safely' comes on and everything shuts down on the dash (car drives fine inc brakes) 2mins later it carrys on as normal. Then the dash goes off again and flashes the battery symbol for a few moments, then again all back to normal. Then 'power steering service required' comes on, along with engine system service required and its like i lose turbo when i put my foot down.. it takes a few seconds to kick in (All of this within 10mins on my way to work) now the seatbelt beeper beeps constantly like i dont have my seatbelt on (but i do) a few days ago, it all started working fine, central locking, windows etc! But it lasted 20mins then back to flashing errors.
Now i have noticed that when the error code flashes 'reverse sensor service required' everything works perfectly.
Its driving me mad! Iv had a new battery in the car and fob, CEM i have checked and all fine, along with all fuses.
Does anyone have any ideas what the hell is going on with it? I love the car so much and i really dont want to get rid, but when i can't use it cus im locked out of the boot its useless to me. Please help

it sound like you need to get it checked with vida this should tell you where the fault lies this sound like a loss of power to components possibly a broken wire or short to ground without proper diagnostics every thing else is guesswork.

I have taken it to my local volvo garage today to be plugged in, it came back with no faults. Due to its age they dont seem to care about getting it sorted. I guess electrical issues is more hassle than the car is worth to them.

that's typical of some dealers try to find a small independent volvo specialist who will help find your problem or alternatively try to find a good auto electrician. or a local volvo enthusiast who may help. ps check battery voltage and alternator volvos are known to panic when voltages are low you could try borrowing a know good battery to see if any thing changes
