Hi
The wife was driving back the other day in the 2014 1.6 TDi when she got warning lights come on. Tyre pressures, ABS , Stop Start couple of others.
I checked the tyre pressures first and fine. A neighbour checked battery and only showing 11.2v he said that's probably why!
Bought a new ABS battery slightly different from Ah 70 to 68.
I fitted it (Doh) not knowing it needs the values changing so car knows its a new battery. Anyway Warnings are all still there even after a run?
Got a OBDEleven but don't really understand it fully. Grateful for some guidance please.

Get it to someone who can code (adapt it). An OBDeleven can do it and remember there's more than just the Amp hours that need to be adapted. The dealer is the easiest. My dealer did mine for no charge.

It will need recoding all info in the first post in my 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

Quote:-
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!
