Saturday my daughter was sick in the passenger seat of my 2010 RRS. Cleaned it all up and everything was ok over the weekend.
Today i gave the seat a freshen up cause i could smell it a little. Now my car wont start at all, totally no power. Start button does nothing.
Any ideas????

Battery flat from having the doors open?

Which passenger seat, the main computer is under the driver seat 2016 RRS 4.4 TDV8 Autobiography Dynamic in Montalcino Red and Stealth Kit

AA attended and diagnosed that the issue was a flat battery.
The guy came in a Land Rover/Jaguar branded van which was reassuring, he jump started the car and checked it over.
Apparently due to smart key being close to the car and the car not being started for a while plus the interior lights being on, the battery drained.
Seems ok now.

Came out this morning, started my car and once again it was flat. As soon as i pressed the start button the clock began turning round and round. Anyway got the mrs car and jumped it then it was ok. Also got a error message, lean when cornering. Does this sound battery related?

Yes i have had the same problems Battery going flat when doors were open when cleaning interia. When car was jump started all the info on dash went back to manufacture date, clock went to same time of manufacture. And all different faults came up ,Gearbox fault, Low fuel, etc. everything went back to normal after reset clock and date, and stopped engine and started it again. This happened to me twice,so i bought an upgrade 100ah battery. Because i was only doing short jouneys. Have had no problems since. itisme

Our's does this after not running for a while. Generally only short trips too. Been in for numerous diagnostics but no one can find a problem but has killed 3 batteries in a year & getting very fed up with it.
Even after going out for 200+ miles on Saturday come Monday dead again
Any ideas?

Sounds like a battery conditioner might be helpful. Leave it plugged in to the vehicle when you're not using it and it will look after the battery for you. The problem with occasional use is that, if the battery isn't in perfect condition then you might never get it fully charged even by a 200mile run.

Are you running the standard flooded lead plates battery or is it a newer AGM one? The latter is designed for use with stop-start systems so is a bit more resilient.

As for why it's killing batteries, have you checked the rear hatch switch? They corrode and can cause a short that kills batteries if left for a period of time. Very easy to replace - less than £20 to do it yourself in about 10 minutes. 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

If the battery has gone flat, it will need fully charged with an external charger, to get it back up to 100%

Just the way the "smart charging" system works

Are you replaceing with the same type of battery ? I have heard different people saying that a battery is a battery. not true. It needs the same ah and possibly same CCA or higher. As been said before try the tailgate switch. I had battery problems when leaving the tailgate open. Doing various jobs Result no starter next morning  itisme

Its not the micro switch that corrodes, Its the alloy hinge device that pushes onto the switch that gets powdery and doesn't work properly. It is located under the rubber surround that you press to open top of tailgate. I have had this problem with both of my previous RRS. Toook them apart cleaned them and gave them some WD40 treatment ,Problem Solved itisme

OP - Relating to the sick on the seat, get yourself some enzyme cleaner else the smell will never go away

A couple of good ones:
Autosmart's Biobrisk - see ebay
Valet Pro Enzyme cleaner. ON THE WAY: BMW F21 M140i
MERCEDES GL350 - Metallic Navy Blue w/Grey interior

GOING: BMW F31 335D MSport+ xDrive Touring
GONE: Land Rover Discovery 4 HSE - Stornaway Grey w/Black Interior (wish we'd kept it )
GONE: BMW F10 520D MSport - Carbon Black
GONE:MY12 RRS SDV6 HSE Sumatra/Ivory/Grand Black Privacy glass

Died again, wouldnt jump start so had to call out the AA. Eventually got it started then i delivered it back to the dealer. Hopefully its covered by the warranty.

Dropped the car off yesterday afternoon and told them what the AA said. Even left the AA invoice explaining the fault, so car was being looked at today at 8.30am. I had to call them to find out what was wrong 2 hrs later only to be told it failed to start this morning. Another 2hrs after i called again it had been diagnosed as having a faulty cell in the battery. So i asked what they planned to do, said they've ordered a new battery. Unsure when it will arrive and unable to say if the warranty will cover the costs. Still waiting for them to say how much the battery is? And that was at 11.50am
Awful customer service again.
