Indicator light for a 1997 bmw 328i

These cars have a LKM light control module know for failure. Tons of relays and brain boxes also common failures. You need a BMW expert, and maybe someone here knows more.

Sounds like your battery is weak. BMW's don behave like other cars when the battery is weak. The BMW will prevent the starter from engaging, but leaves power to the interior.

Alternator. Have it tested with a voltmeter while on the car and running. Or take it off and have it tested. The current to run the car and the accessories is from the alternator when the engine is running. The battery light coming on alerts you that the alternator is not doing its job.

Check the blown wire on the plug connection of the tail lights. They usualy burn. Then you just have to cut is off and give it an earth on the light circuit board.

check the fuses

You have oil leaks getting on the exhaust system, they are getting into the car, have the car checked over to find source of leaks.

It sounds like you may have a poor connection in the ignition switch. When this occurs move the key a little and see if problems clear.

I *think* that's the solenoid on the charcoal canister which is part of the vapor return system. Do you smell fuel? Probably should get a pro to diagnose that one. However you can find the canister under the spare tire if you want to have a look for something obvious.

sounds to me like the refrigerant is low,when the compressor turns on and off this is usually the issue.have the system charged.
