V70 strange new years gremlins today, help pls

[gsxf1100]

Just had a bad experience.
2003 v70 d5175000 miles
gearbox kicked back while driving down hill,
Second time all electrics gone and engine off.
Rolled on the roadside, switched back on. Started.
Driving 4 miles lights in dash and all controls I. E tacho, rev counter et. off no illumination no gearbox illumination.
Sluggish gear switch.
That happen 6times.
At one point i had no power at all to start after switching it off.
Seemed a kind of reset by doing it.

Opened driver door and all lights and tacho back on.

Started and drove home.

Now it has the stupid srs airbag system immediately required and the yellow light on.

Any idea what all that caused or what I'm looking for ¿
I have no vidas and unless I know the car drives again and I can trust it again I don't want to invest in the software as I may not even buy another volvo if this is a major fix.

So, trying to figure out what I'm looking for on that situation.


Batterie is 12.8 volt, alternator works, all fuses fine, and now starting without problems, and no other problem when I just drove around to check if it's happen again.

Just the srs is still telling me to find a way to get rid off without servicing and playing volvo for this, as none of them opened up.

Anyone can give some Ideas on those symptoms please?

post your location someone with vida may read fault codes for you.

Get your CEM checked for water damage or ingress.

I have no useful information for you unfortunately however I do hope you get it fixed and that the solution is something simple.

If you cant find any one local to help you with reading the DTC's I have an Icarsoft code reader that will read all DTC's on your car , I am only in mansfield so I could drive down to you if needed.

Edit should have also said can clear DTC's as well including SRS ABS etc....

I may manage to come up.
I see a guy with a garage and see if he can read the code today.
Iet you know..
Thanks.

Right,
My Friend with a garage isn't back till Wednesday.

I checked this ecm, which is a pain in the ass to get out.
No melting visible, no damp to see or feel.

The DIM, not sure.
. And if this need replacing.
Certain I don't spend this money to volvo, putting crap in there cars so you come back spend more money to them, or for a second hand 300 without guarantee.

The resale value or even the general value of the car isn't worth that amount and is always something else can break.

I can defo not find a replacement DIM for my model when I just checked.

So I have to see what happen on Wednesday or travel and take the offer to read the codes to make my mind up.

If it's not easy to fix or trustable running by next weekend I just go and buy another car. Lol

its possible that your battery is failing try charging the battery over night or try a known good battery on the car your symptoms are common when low power is detected .
