Hi I have a insignia 2012 the battery was being charged with a 24v battery charger by mistake since then the car won’t start, a new battery has been put on the car but still no joy.
any ideas ?

Thanks

Check all the fuses and fusible links if equipped.

Overvoltage may have bricked any number of modules.

Assuming this is an uk vehicle, replacing all fried components might be more expensive then the car itself.

Hi,

what do you mean with "won't start" ?
Does it crank and just not starting? Or do you have nothing at all even when turning on the ignition?

In any case, before going to deep into something, check ALL the fuses. if they are all fine... the next item "in the line" would be the ecu modules itself. And than it is realy bad situation.

Even I believe MOST of the ecu's etc should handle 24V without burning Because the voltage regulators inside are never just for 12V battery voltage. Some even can handle up to 48V in and still have an 12V or 5V out (depending on the ecu).

So... chances are there, but I hope for you it's just an fuse

And check the Ground-Connection points. If something gets hot from overvoltage those points are the first that melt. For testing you could use an jumper wire and attach an ground wire from Battery - to the cassis or the engine, and see if something returns to live.

thanks for the replies , I can hear the fuel pump but that’s about it no click no crank nothing
The mileage screen comes on the stalk for menu button etc works .
Multimedia screen/ buttons not working
Windows not working
Doors or key don’t work

will be investigating more to see going to check the fuse boards and then modules
Does anyone know how to code another module into the car ? If I needed a new BCM or something
Thanks

If brand new module - buy subscription to SPS and it will take care of it.
If used - need to be handled with DPS (VIN/PIN relearn), and then with SPS to load correct calibration files.

Thanks il have to research more into this..

Would another option work by swapping a full ecu kit into the car e.
Clocks , keys barrel , all modules etc aslong it’s from similar year same spec and same engine ?

Thanks

If you don't care about VIN mismatch between electronics and body frame...

However, it is much cheaper and easier to perform a relearn. Some sellers may even offer to program VIN and calibrations, so it is a plug-and-play job for customer.

Access to SPS is ~50 EUR + VAT - and you can program all modules which can be updated to newer FW.
VIN/PIN relearn files for DPS may cost you 100-200$ in total. However, it requires some DIY and research to perform everything correctly.

Thanks for the reply where’s the best place to begin to learn about programming the modules etc with SPS DPS
I’ve done coding modules before BMW so would like to learn how to do it with Vauxhall

Thanks

* Update *

I’ve changed all modules and now I get this error shown in the pic.
My car doors are working now all dead locks gone
Windows working
all electrics etc
But car won’t start if I turn the key a few times it will begin to start but cut off.

Would this be related to the immobiliser kicking in ?
