Hi, 

 

I have seen you need to code a new battery when replacing on a Skoda Octavia mk3 with start/stop.

That's the battery I bought, is this potentially something anyone could assist with?

 

Thanks

I could be wrong, but I don't think that's a stop/start battery!  Happy to be corrected if wrong.

If yours is an "027" then there's your choices, I have used Tanya before, no problems and cheaper than EECP

 

Check this list, and perhaps tag them, or PM

I have used Tayna for every new car battery I have needed for over 15 years, always a good price and quick delivery.

So you have EFB type, and if you look again at the Tanya EFB list above, there's 3x choices that match the 640Ah capacity.

Exide, Varta and Bosch.  Varta & Bosch are made in same factory, and often Varta is the VAG OEM choice fitted.

 

Your choice as it's your money as to what you buy.

 

Now you just need someone to help you swap, clear codes and adapt new battery to the car.

 

 

p.s. You could also upgrade to the AGM type also, they are tougher than the EFB (optional)

Was thinking this one, about what I was spending at ECP anyway

The factory fit AGM is 68Ah 760CCA, that one is bigger so would need a larger outer heat shield material.

That AGM you listed should be same dimensions as you have, and should still work.

I did a big thread (all info in first post) on swapping out the mid sized battery for a bigger case size...all info on case sizes & VCDS coding etc in this thread here:-

 

How to retro-fit a bigger capacity battery to a Mk7 Golf | GOLFMK7 - VW GTI MKVII Forum / VW Golf R Forum / VW Golf MKVII Forum

 

Quotes:-

 

If the car has "stop/start" auto engine shutoff & restart (not to be confused with KESSY which is keyless entry & start).....you need at least an EFB type & pefferably an AGM type.

 

This is what VAG fit at the factory:-

For cars WITH "Start/Stop” eco engine shut off (BlueMotion II):-
59Ah/320A (DIN), H5 size, EFB type
69Ah/360A (DIN), H6 size, EFB type
68Ah/380A (DIN), H6 size, AGM type

 

H5 is the mid sized case, H6 is the biggest case size.

 

Varta who make some of the batteries for VAG confirmed that standard battery case sizes are used to make the VW factory batteries, but that the Ah capacities are “special” to VW for those case sizes. Basically, VW are confusing us to make sure we end up buying a direct replacement battery from them when in fact a standard battery which is available from any auto parts supplier will fit & do the job!!

 

So long as the case size is the same or bigger than your factory battery & the Ah/CCA is better then buy what every you can from any car parts supplier...

 

VCDS coding required
From the Main screen:-
Select Control Module [Select]
[19-CAN Gateway]
Advanced Functions screen:-
[Adaptions-10]
New value choice screen:-
Change the following four channels, inputting the relevant data about the new battery.
IDE03256-MAS06105-Battery adaptation-Rated battery capacity
IDE03256-MAS06106-Battery adaptation-Battery technology
IDE03256-MAS06107-Battery adaptation-Battery manufacturer
IDE03256-MAS06108-Battery adaptation-Battery Serial Number

When you click on "Battery technology" (using VCDS 21.3.0) a drop down list appears with the following options (= actual meaning):-
Wet = Standard Lead Acid
Fleece = Standard A.G.M.
Wickel6V
Wickel12V
Ultracap
Gel = Standard Gel Lead Acid
Lithium ions = Standard LiFePO4
EFB = Standard E.F.B.
Binary - AGM = "Bipolar" A.G.M. type
EFB+ = E.F.B. "Plus" type
Not_assigned_10
Not_assigned_11
Not_assigned_12
Not_assigned_13
Not_assigned_14
Unknown

According to various sources of information, including numerous car scans & threads on Ross-Tech, "Fleece" is for standard AGM batteries, "EFB" is for standard EFB batteries, & "Wet" is for standard lead acid batteries, as these settings are used at the factory. The setting of "Binary - AGM" is apparently for specialist "Bipolar AGM" batteries! Also the drop down list is from VCDS & not generated by your car's BCM, therefore, your car may not support all the options on the list, & the BCM will reject the value when you tell it to accept it!

Battery BEM codes are now redundant with the above separate channels. The most important channels are:- Rated battery capacity, Battery technology, & Battery Serial Number. For the Battery Serial Number, just change one digit of the old one. This channel tells the BCM that a new battery has been installed & to relearn the new battery & forget any “learnt values” for the old battery!

Thanks for that @fabdavrav, just need to find someone local and online here who could assist with having vcds

You would need to tag a few names in this post, and see who responds.

You are in a little bit of a desert there, and hopefully someone will respond.
