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.
It will need recoding all info in the first post in my thread here:-

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

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!
