Hi all as the title says im going to change the battery on my 2001 2.2dti it has the cdr 2005 radio fitted and i dont have the code for it will i loose the code by changing the battery if so what method can i use to save the code
TIA
-
Likely, unless previous owner has disabled the code (unlikely).
Carpass from dealer, assuming its the original.
-
bummer :(
-
is there a way to disable prior to removal
-

Indeed. But you need the code to disable it ;)
It would be a pretty pointless security device otherwise ;D
-
full of good news aint you TB ;D
-
Unlike the carpass which may not even show the correct radio, I can certainly help with decoding of that model

im doing a 600mile round trip up scotland setting off in the morning i need my music lol
would this work if i put battery charger on pos and neg somewhere other than the battery then change the battery what you think ??
-
if i do loose the code Dave it will be sent to you for you to work your magic
-
just thinking outloud here :o but wouldnt it be at all possible to connect say a charger/booster or even another battery onto the the original battery clamps ? then when you disconnect the original battery the back up you have used will still put electric through therefore keeping everything live and working untill new battery is fitted :-\ or would having the the back up and a new battery cause an excessive voltage and fry things :-\
as i said just thinking outloud :y

Not advisable --
Many garages used to use a similar device called a codesaver that was plugged into the cigarette lighter socket, but for some unknown reason this used to interfere with SRS systems and could even case airbags to deploy, which is why this practice is no longer followed.
-
ahhh ok dave just wondered if it was feasible ;)
really dont want to deploy airbags just to save a radio code ::)
-
I saw the aftermath at a Volvo garage recently, where something similar had been done and airbags deployed.
I dread to think of the costs involved, as including the side curtains, we counted 11 deployments !!
:-X

Yep, done that with no probs ;)
-
Me too. ;)

Changed my battery recently, connected a small battery charger set to trickle charge, clipped small crock clips on terminals and removed- replaced battery without any problems and kept all codes. I can not think of any reasons why this method would cause a problem?
-
i wiil give it a go and report back
-

Neither can we, but I hear of it happening at least one a week at the moment, but really do not understand why. I can only think that some sort of voltage spike is being recorded somewhere?
-

that is what i was trying to get at in my original post, the voltage spike will occur when you fit the clamps on new battery with the back up battery/charger still attatched, you will get excessive voltage going through the system maybe only for a split second until the back up battery/charger is disconnected, this spike could cause what dave is saying :y
-
Way back when Noah first put an SRS system on his Ark, the general advice at the time was to put the headlights on so that any voltage surge would dissipate through the lighting system and would therefore prevent damage from voltage spikes.
However, have you ever tried to do this? as the voltage spike / arc from something major being powered up like the lights can actually burn out and damage the battery terminal as you are trying to fit it
Cant win !!
I think that changing the battery "quickly" gives you a 50/50 chance as to whether the code will be needed, and worst case scenario, I can decode it anyway, so not much of a problem really.
-
Job done code saved used battery charger on terminals worked very well im happy now the car will start in the morning and still have music for my trip :y thanks for all the advice and offers to decode off Dave
-
Glad you are sorted
;)
