Hi, i have an Octavia estate 2L diesel Mk 5, which i believe is a 5e5. First thing in the mornings it can take a bit of turning before it starts. Once it's going its not to bad, but i do charge it every now and then and then it behaves for a little while. I do get some funny messages when its a bit slow to start, so i am thinking that maybe its time for a new battery as it is still on its original battery. My question is; AGM or EFB battery. Some say EFB, but the car is fitted with a Varta AGM battery. Will it make a difference if a EFB battery is fitted.

Regards.

10 year old battery is a good innings these days with stop/start tech, so yes, a new battery sounds a good idea.

Best stick with AGM otherwise you will have to change the battery type coding.

Thanks for the reply. You say i'll have to change type coding. I have to ask what is the battery type coding?

Cheers

I have just seen a YOU TUBE video on battery coding. The video even recommends coding for the same type of battery.

If you're fitting the same type and capacity of battery all you have to do is change one digit of the serial number.

Its having the equipment to change even one digit is the issue. Physically replacing the battery isn't an issue, it's the code.

Whereabouts are you?

I've just been through this very issue.. original 2015 battery, so I was pretty sure I'd need to replace it before next winter.

I'd already decided I want to keep this car a good while, and I'd be mostly DIY (not had to pay for a battery change for over 30 years), so I invested in a genuine VCDS setup.

I've seen a couple of folks on here say they paid GBP 250+ for a battery and coding, so having paid 225 for the vcds (basic, 3-vin version ) then just under a hundred pounds for a larger capacity battery (same size battery would have been a few quid cheaper) I feel ok. Easy to fill in the info for the battery change, then a few days later did the oil and filters change so could reset the service interval. Also easy.. plenty of advice and instruction online.

Reckon I've pretty much broken even already.

Mine was EFB, so stayed with that.. most advice seems to be that if you already have AGM then stay with that.

It may be that someone local to you has the Unlimited VIN version of VCDS and might be up for coding a new battery for beer tokens or similar!

Winchester area. We do have a local Facebook site for the area i live in so i may post on there to see if anybody has any information about getting the battery coded.

I have seen a youtube video for coding the battery with a OBD11. Can you use a OBD2.

I'm in North Derbyshire, otherwise I could have helped.

I have OBDeleven.

I doubt that you could use a generic scanner/code reader unless it's very high-end.

You need to tell the car if you are changing the battery, even if it is the exact same thing.

Looking at the VCDS map, you have a few people local to you. It looks like @SJFISHER67 is from the Winchester area.
