Looks like need to treat her to new main battery.

What is the recommended process for removal and fitting ?

I have a MFL 2.5V6 CDX on a V plate.  Looks like there is a 72Ah one same dimensions 

Am I correct that process is:

• Turn ignition off and remove key
• disconnect negative within 15 sec
• then disconnect positive and make cuppa
• remove old and locate new battery connecting positive terminal first then negative
• enter radio code and start car as normal

I read somewhere about needing to reset key immobiliser and windows ? Or is this not necessary ?

Thanks in advance.

Andy.

No tea break

You will need to reset one touch window operaton plus sunroof [if fitted].  You will also need radio code.

Ahh, I read somewhere to let things discharge to avoid Airbag light coming on ?  Unless that is on the Face lift only and so not needed on my MFL so culpa when all done ! ?

Correct on all counts. You can make life a bit easier by slackening the -ve battery terminal off before you start

You have airbags on your MFL too

Following procedure will not cause Airbag light to come on following new battery reconnection ?

You'll be OK just swapping the battery.

You'll only have problems if you have any of the airbag system disconnected and turn the ignition on (with the battery still connected) It'd need re-setting even if you fix the fault or reconnect it all

Cheers.  Sounds like should be simple.

Any advice on how to reset the windows and sunroof ?

Please read the manual

Never re-set a sunroof myself so don't know on that bit,but windows easy.Just press and hold each window switch to the closed position and after a second or two you should here a faint "click"and that's that particular window sorted.

What can go wrong ! 

Must lube the securing bolt as not moved since Fritz put in on 15 years ago in Germany

I don't think you have a battery that is 15 years old

[DrAndyB]

I don't think you have a battery that is 15 years old

I do have a 15 year old battery    I think its a world record 

I have had the car from 6 months old and still has the Original GM Battery on  and never been replaced 

She has been getting a little slower on turnover and battery I suspect now getting "Tyred !"  Green indicator on battery stopped being green a few years ago !

WOW !!!!

Just got a new GM battery for the Elite from the local dealers, £53 + vat. I bet it will not last 15 years, mind you I bet the car will be gone long before that
