Battery light disappear when I rev to 2000rpm

J’ai actuellement un batterie AGM pour le start and stop hors il ne fonctionne pas ma question est batterie défectueuse ou il faut une EFB/EFB+ ?

They told me at Autozone that the alternator was not charging the battery,
When I put the battery in and after driving for a few minutes the battery light comes on on the dashboard for a few minutes

When I disconnect the battery terminal, the car turns off every day for some time, approximately hours, as the car runs on battery power only. When I disconnect one of the battery terminals, the engine is cleaned immediately. When I move the positive terminal wire of the car with the green fuse box and I start it and disconnect the battery again, the problem goes away for a short period and then returns on its own after four to five hours, or usually in the morning.

The electrical system goes off when I try to start the ignition thereby causing the engine not to start and all lights off untilk I touch battery head before light and electrical systems come up again but still won't start

Hello everyone, Can i get a help regarding an issue recently I changed the alternator so I had to drove to the house with no alternator only battery power source so when I replaced it all good but when I drive for 1h the ESP light comes on on my dash with amber color and don't go until I turn off the car but again when I drive almost 1h/ 45min comes on again what's the issue here?! What should I do ?!

I have a Golf 5 GTI with DSG transmission. Yesterday, when I stopped at a traffic light, the engine suddenly stalled. There was still power and the lights were working. I later noticed that the negative battery cable was slightly loose.
After that, when I tried to park, the gearbox started behaving abnormally. It was shifting freely between R, N, and D without proper engagement. Then it got completely stuck in P and cannot be moved anymore.
I have checked all the fuses and none of them are blown.
A diagnostic scan shows multiple errors including communication faults, implausible signals, and ignition interruption.
Could this be caused by the loose battery connection, or is it likely a mechatronic/DSG failure?

Golf 5 1.9 TDI Difficulty starting the engine after being parked for a long time but The battery is working fine. I think the problem is related to the fuel.

Good morning,
Basically the car is perfect, nice start, no problem at all but when I leave the car on the sun (I'm on Sicily/Italy so for now outside we have like 42/48°) the car won't start and does some noise, other than this if it start and I turn on the AC or the lights it will stop them off but not just them but also the arrows sign, clacson, lights and comfort buttons and at the very end the dashboard will turn off and give absolutely no sign, for have new life signal from her I have either to wait or leave it away from the sun

We tried changing the piece behind the keyhole, we created a new negative for the engine, we changed every fuse and relè but still nothing

One thing that I can say is that when the car won't start the battery sign doesn't appear

Good day. I noticed when the idling increase the alternator voltage decreases and sometime times it happens when I turn the heater fun to max. I changed the alternator and battery the car charged yup to 14 volts. I switched of the car after 2 hours I came back and turned the engine on and the alternator was not charging anymore the battery was also drained...

In the last few weeks, I replaced two wheel bearing hubs and a door lock actually hit a module, but all went well. It seems.
I wanted to try to clear any errors on the instrument cluster as well as a add blue will not stop in 500 miles era which previously I went 1000 miles over that 500 and all is well, I disconnected the battery pulled one fuse or relay at a time and reinstalled once complete. I tried to start the vehicle it fires up and runs for two seconds always the same just a couple seconds as the service break light came on and then dies. I know it’s not the engine. It’s a clean start and shut down. I’m thinking it may be electrical. Any help would be greatly appreciated before I take it to the garage.

Battery not charging error

Battery discharges too quickly, completely flat if not driven for 3 days. Parasitic draw somewhere, all fuses seem ok, resting current is roughly 500mA, rather than 15mA. Cigarette lighter doesn't work but fuse is fine. Where do i start?

There is water on the driver's feet and the passenger's feet behind the driver, the floor is completely wet. Can anyone help? The water that runs down the windshield is clogged, the water runs normally, there is no water in the battery, but whenever it rains, everything gets wet at the feet of the driver and the passenger behind, and the passenger door behind the driver also stops opening. How can I fix this?

Hi, i recently got a golf 2 from 91 with a 1.3l nz engine. A little backstory to this: befor i started to work on it i cranked the car over and gave a little gas via the intake to see if it starts. Well to my luck it started without a problem (i want to make it into a low budget rally car and i found it abandoned with wasps in it and mice). Now, i repaired the fuel system by replacing the fuel pumps with just one from bmw that makes 3bar of pressure. I bypassed the high pressure fuel pump tank so it goes directly to the engine. After that i changed the battery terminals because they were broke… Read complete

The cluster will not come on when turning the key even though battery is connected and the starter works when testing alone.
