Warning indicator light

There is no warning light for catalytic converter heating uo. Brake light usually is a exclamation mark inside a circle inside parentheses. What you are describing sounds more like a temperature warning light for the cooling system.

Cluster warning lights

Whenever this warning or any other stays on in the dash it is indicating that the systems control module has detected a fault, it then disables the system as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

this light for coolant level indicator top up coolant level then s.w off and on , check for coolant leakage may be leakage from radiator sender.

Its a warning to check brakes,pads have sensors to warn you early
Get all pads checked
Look in owners manual so you know what all warning lights are

it sounds like you are talking about your "Tire Pressure indicator" light on your dash. you have to check your tire pressure and follow the instructions in your owners manual to reset your tire pressure indicator.

That is your Low Tire Pressure warning light. You need to get your tire pressures checked.

it's sounds like it's the brake pad wear indicator light. you probably need new brakes on either the front or rear of the car

Hi,
This is an indication of something having to do with your brakes. You need to check your brake pads incase they are worn out. If nothing wrong with it, then your car is likely getting too old....an you need to start ignoring some of those unnecessary warning lights....it happens when bmws exceed their "road life".

hi think its brake fluid warning light if it flashes if doesnt flas then it just parking brake indicator my i reckon it first one so check brake levels if necessary top up above minimum if not theres a fault either the light it self or braking system hope this helps

A circle with lines around it - depends where it is -
If its a top left light, then it should be a circle with an exclamation mark in the middle, and two lines running part way round the outside (1 to 5pm and 7 - 11pm). Thats the handbrake and brake fluid light which comes on for about 3 seconds when you start the engine ... if it comes on at any other time - seek help.
If its top centre, and has ABS in the middle, then its the anti lock braking light. Similar to above, lights up for a few seconds at start.

Muffler with lines coming off it - are they pointing outwards from the circle, (with a thermometer in the middle = transmission oil temperature guage), or are they on the left and all parallel (which would be main beam indicator, which lights up blue when on)
