V8 Vantage Flat Battery-Urgent

[Gio1210]

Hi guys, the battery on my V8 Vantage (2010 SS) went flat so i had to jump start the car. Now the following is not working:

1. Driver Window (not moving at all)
2. Door Mirrors (both driver and passenger)
3. Roof (Once i press the button the message 'Roof Failure' is displayed).
4. Lock/Unlock from inside the car
5. Rear fog lights not working.
6. Driver's door does not lock, even from outside using the fob.

It looks something went wrong (e.g. module) in the driver's side.

Once the car was jump started i took it for a long drive and then plugged the battery conditioner.

Any ideas?

P.s: The window reset procedure does not work at all. Passenger window works just fine BUT only from the passenger switch.

Try a battery disconnect (remove the earth lead) for 30 seconds.

Is it just me that thinks this is absolutely ridiculous that a flat battery and subsequent jump start, can cause a list of faults as long as your arm

Jeez AM its just a flat battery,...... Get your st in order...

No,I think exactly the same thing as well. It's so bad you have to wonder if it's not by design.

Range Rover P38s did this too, pain in the arse.

It's ridiculous....

When I go away in the summer, I take the battery off my old Jeep, so I can leave it on charge, and no one can nick the car...(not that there's anyone daft enough to want it)

But when I come back, stick the battery back on, the only thing that needs doing is to re enter the radio code......

When I see crap like this on the forums.... It certainly makes me less sorry, I'm no longer an owner

Wait until the P38 fails to even recognise the key after changing the battery. Whole new level of frustration and pain?

A reset is required when the windows are working but not open/close for the doors to open. This is not the case. The driver window does not move.

That would be just to boring!

It may just be that the electrics are not working correctly as the battery is not putting out enough voltage if the battery is now faulty. I had similar issues with my first V8 and disappeared as soon as a new battery was fitted.

Thank you Greg! Will order a new battery

I had Jag XK8 and when the battery got low all kinds of electrical gremlins showed up with the windows, alarms etc and a recharge or new battery would fix it. A word of caution about jumping off new electronic laden cars:I jumped a Lotus Esprit V8 and fried the $2000 ECU. Since then I have heard other horror stories from jump starting cars. Now I only will put on a battery charger overnight unless it is a dire emergency.

This. As you have said the window reset does not work and unless a roof module has failed at the same time (possible but unlikely) it just needs new battery.

My last vantage Coupe took a hissy when my battery went flat - completely fine when the new one went in.

The new battery will arrive in a few days.

Would you advise keeping the car (with the old battery) on the battery conditioner for now?

[Pentoman]

1980s BMWs and Mercs have a fuse on the over voltage protection relay that can often blow when you jump start them. In turn this would frequently cause poor running and other issues depending on the equipment fitted to the vehicle. A lot of owner's manuals nowadays don't recommend jump starting for these sorts of reasons. Silly if you're coming from the old days of jump starting whenever you feel like it.

Update: Battery was replaced with a Bosch S5 Silver Plus (100Ah - 830A) , both Ah and cranking figures higher than the Varta Battery which was fitted already on the car.

All of the problems below have disappeared and the car works just fine!!

1. Driver Window (not moving at all)
2. Door Mirrors (both driver and passenger)
3. Roof (Once i press the button the message 'Roof Failure' is displayed).
4. Lock/Unlock from inside the car
5. Rear fog lights not working.
6. Driver's door does not lock, even from outside using the fob.

However, i have noticed 2 black strings on top of the battery (not connected, just loose). See first image

Do you know what these might be?

Thanks a lot guys!

Exactly the same as the Varta I have just fitted, but different branding. £85 delivered. Suggest you put the red cover on properly. Strings look like the rear parcel shelf hangers!
