Flat battery advice

Post by Duffs » Mon Oct 19, 2009 7:38 pm

Hi guys, sorry if this subject has been covered before, just returned from abroad and despite repeatedly telling the wife to keep the battery charged, she has allowed it to go flat - dead as the proverbially doornail.
I have purchased a new battery, are there any precautions i should make before refitting, especially with regard to the alarm/immobiliser system? I presume i will need to also find the radio code. Women don't you love them!!!

Thanks for any help

I disconnect my battery every 6 weeks when I go to work and the only thing I need to do when I re-connect it 6 weeks later is enter the radio security code. Hope this helps, Angus

Just the radio code.

Also a whole bunch of errors will be stored in the car's memory so if you have a vagcom then you should clear them. If you haven't then it doesn't matter :)

Also, the throttle body will need to calibrate itself. Turn the ignition switch to the on position (but don't start the engine) and leave it like that for at least 10 seconds. You'll probably hear it calibrating itself.

I bought a battery conditioner to avoid this problem. I plumbed a connector through from the wheel well to the rear seats that I plug in when I park the car. Keeps it tiptop.

What type do you use? I think it would be a well worthwhile investment.

Excellent. I see them on eBay. Does 45 pounds sound reasonable?

Thanks for your help guys, i also have a C-Tec charger/conditioner for the motorbike - i tried to use that but the battery was too far gone on the car.

Just about to fit the battery - fingers crossed,

Yes, I think I paid slightly more for mine. Also from ebay. Very good vendor. Do you want me to try and find his pseudo?

Good luck, Duffs :)

I changed my battery recently. No issues at all other than the radio code.

I just wanted to double check - I know when you disconnect the battery you need the radio code for RNS-D, but what about RNS-E? I think I read a post a short while back that stated the RNS-E remembers the code - can anyone confirm this please.

Cheers,

Mo.
