Thanks @SRGTD - it was indeed coded (type changed from EFB to AGM, correct Ah capacity and the BEM code changed). The battery seems good - health test shows 91% health, and the voltage I'm seeing never dips below 12.5v (according to the tracker). Start/Stop also works as expected...
This is the ...

Amber LIM warning sporadically appearing (DSG Polo AW, 2021)
Wasn't sure if this belongs in the electrical bit of the forum or here, but decided here is likely best.
Got my Polo (2021, AW DSG) in April 2024 approved used. Everything was, and has been, great. However, there was an intermittent fault with the speed limiter, where !LIM would display on the ...

Re: Changed battery, now alternator won't charge...
Small (good, albeit confusing) update - I swapped out the battery terminal on the positive side so it fitted better. Tried using the jump pack to keep car settings (unsuccessfully, it turned off). To my surprise, car sits at 14.6v at idle and charges. For comparison, I was at 12.5v when idle before ...

Re: Changed battery, now alternator won't charge...
Thanks John - that's interesting about the SOC around 80-85%.
I've taken the car around (put 430mi on it over the last couple of days) - I think the alternator may have a problem. Looking at the speed vs power line graphs (I've tried to overlay the two but looks like a mess) - the points when I'm ...

Re: Changed battery, now alternator won't charge...
That is another thing that I witnessed after fitting that cheap DVM to the 12V power outlet, even with my old 2011 Audi S4, if I have not used it for a couple of weeks, I'll connect it up to a CTEK charger, after it has been charged fully up by that CTEK, if, a few hours later, I drive that car ...

Re: Changed battery, now alternator won't charge...
did you check the fuse? i think it would be good to change the battery type to AGM in your coding. otherwise the car will charge it like an EFB. that's not very ideal.
I wasn’t aware there is a fuse - fuse box diagrams show nothing for the alternator. In any case, the link between the ...

Re: Changed battery, now alternator won't charge...
Update from this morning: alternator terminal cleaned but no difference! Though I’ve observed something a little bit interesting:
The charge voltage (with engine running) jumps about. Sometimes it’s at 13.5v (this is after the car has sat for about 15 seconds with headlights on to remove surface ...

Re: Changed battery, now alternator won't charge...
Cheers RUM4MO - wanted to make sure it was done as close as to how it would be done in a workshop so sorted the BMS before first start!
Charge light behaving exactly as before. Comes on then goes out alongside all the other warning lights. Diagnostics throws up no codes to do with charging status ...

Changed battery, now alternator won't charge...
I'm having a weird issue with my 2021 Polo AW - the old battery (original WAG) was knackered so thought it would be an easy enough job to replace it. I've changed it out for a 092 Bosch AGM (had a 027 WAG EFB+). Everything fitted fine, just needed to add a 2AWG cable to connect the positive battery ...

Re: Match vs SEL, Facelift vs not... what to choose?!
@strategygoose - welcome to the forum.
I’m pretty certain the very last of the pre-facelift Polos had the centrally positioned ‘Polo’ badge on the tailgate. I think those cars also had the same in car tech that the facelift cars got.
As for alloys on the pre-facelift SEL; they have a painted ...

Match vs SEL, Facelift vs not... what to choose?!
Hi all,
This forum has been incredibly helpful in giving me a tonne of info about Polos. I'm stuck so thought I'd come here for some guidance. I'm especially lost as this would be my first car (ever) and while I know car stuff, the longer-term considerations, like resale value/depreciation, trim ...
