Engine light warning light comeing on?

There may be a fault in your Totally Integrated Power Module. Are the signals coming on and just staying steady? Are yourvparkkng lights working? Hazard warning? If so, I'd start looking at a defective turn signal switch.

* needs new fuses * needs more freeon * and you might need a new car batterey.

any time a warning light comes on there is a problem that needs to be checked out. you don`t say what warning light comes on, oil light, check engine light, coolant light.

Sounds like a wire was not re-installed under the hood. When the alternator or battery were replaced, there are several power wires under the hood that attach to the same power terminal. Look for a RED wire with a large round connector, that is just hanging out in the open air. You need to install it back onto the post that it came off of. good luck.

The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

warning lamp some used for warn low oil pressure, etc.
Wtith the bulbs use for most warning light circuit it is hard to determine whether or not the filamente is good. Will be a good idea to replace the bulb.
For test the faulty warning lamp, turn the ignition switch to START, this light the warning lamp. I f the light does not come on , disconnect the sender switch lead. . Use a jumper wier to connect the sender witch lead to ground. With the ignition in RUN the warning lamp should light. If the lamp is illuminated replace the sending switch. If the light does not come on,either the bulb is burned our or the wiring is damaged.Use test light for confirm voltage is present at the sensor terminal connector. If there the bulb is bad.
God bless you

You'll have to have the computer scanned to get the trouble code to find out.

check the blend door actuators and for a vaccum leak to the hvac

the coolant level is down, add more freeon.

Probably nothing whatsoever to do with you checking the dipstick. On the golf when the warning light flashes, you reset it by opening the bonnet. That is why you think that when you check the dipstick it resets, when in fact it was opening the bonnet. Check your bonnet switch
