2002 530i bmw, has a double car symbol on the dash.

The AC dash light in your 2020 Isuzu NPR indicates that there is an issue with the air conditioning system. This could be due to a number of reasons, such as a faulty compressor, low refrigerant levels, or a bad relay switch. It's important to have a professional technician inspect the system to diagnose and repair the issue as soon as possible.

It is the defective bulb warning light. It is a warning that a bulb has failed and needs to be replaced.There is a similar symbol that is an automatic transmission warning light but from your description I believe it is the bulb warning light. Hope this helps.

You can go online and find the manual for it at BMW's website. It should be fairly easy to find. Wish I could help more. Good luck.

Here is a fix >

Security and Immobilizer System Indicator Symbols Symbols & Tell-tales
These are Security and/or Immobilizer System Indicator symbols used by manufacturers. One of these symbols lights momentarily to indicate that the ignition switch is locked and will need the proper transponder-equipped key to re-start. The vehicle is immobilized otherwise. Green symbols will flash when the vehicle is immobilized.
If the symbol is visible when the vehicle is on, it indicates a malfunction in the security system. If the engine does not start with the correct key, and the security indicator remains on, the system may have a malfunction. You will need to contact your dealer in either case.
Keep the Symbol meanings with you!

You have a tail light not working or a brake light not working.

The vehicle owner's manual will contain that information.

Brake pads warning or something wrong with the sensor good luck we had the same problem

That's your brake pad wear indicator ---means you need to have your brakes checked / replaced either in the front or rear.
It's a wear sensor wire ooked to the brake pad and when the pad wear down to the wire it lights up the dash warning light.

check your owners manual it should give u the meaning of this symbol If u don not have the manual call the dealer asap

I know your problem has been fixed by now, but I wanted to answer in case anyone else is looking for this. That symbol is indicative of a TPMS (Tire Pressure Management System) malfunction. It more than likely meant that one or more of your tires were low. But could also mean that your car's onboard computer can no longer monitor the system at all and needs fixed.
