BMW battery...who can register and code in Cardiff?
Discussion
I'm pretty sure the battery in my 2008 520D hasn't been coded correctly to the car - I assume whoever historically replaced it just popped a "similar" battery in and thought that was it! I don't particularly want to go back to the main dealer for this so was wondering if there's anyone in Cardiff / Bridgend who offer the registering and coding facility?
I assume your car must be a stop/start?
Is it suffering from any problems?
It isn't coding that's required, just need to tell the car it is fitted with a new battery, if the battery is now fairly old this may be a pointless exercise.
I cover Cardiff and I have the facility to tell the car its fitted with a new battery.

It's not stop/start but would have originally been fitted with an AGM battery. The replacement certainly isn't AGM so the car would need to be registered and coded for this battery. My other option is to buy an AGM replacement (equivalent to the original), and then just get it registered.
edit...and yes, I'm getting the excessive discharge warning and low battery warning. But if my car is coded for an AGM battery the charge levels are lower than for a wet cell so it may not be receiving a full charge.

Is it your original battery? If so, assuming you purchase the same spec of battery (and that includes whether it's AGM or a wet cell), then you just need to register the new battery with the car. It lets the car know that you have fitted a new battery. If you are changing the spec of the battery (amps, wet or dry cell etc), then you need to tell the car what battery you have fitted which is called coding. Both registering and coding require that you're hooked up to a computer be it at the dealer, specialist or whoever.
Hmmm, why do people insist on fitting substandard batteries into the cars to save a few quid which could cost you more in the long run?... If it had an AGM then it should be replaced with an equivalent spec AGM.
I am able to tell the system a new battery is fitted but I have never had the need to programme a different battery in, I will have to see if one of my systems is capable of this, unfortunately the only way I can tell is if they are plugged into a car that requires this facility.
Trouble is looking at it if the battery has been fitted for some time telling it that it has a new different battery may improve the charging performance but still not be right as it is now a used battery and the ECU will assume its new. Batteries lose performance literally straight from the first fit to a vehicle.

Oh how I laugh at modern cars and all the crap they throw at you.
Never going to buy one.
What do you do in 10-15 years or so time when all these modern cars are now old Never going to buy one.
