not the pump but air in the system or a broken wire to the coolant level sensor
that sensor at the top of the radiator tank has to be completely immersed in coolant or the circuit is broken and the light comes on
same effect id the wire to that sensor is broken in the insulation
vw beetles do not have a temp gauge so instead when the car is cold the light is blue at normal temp no light when over heating or low coolant red light and it beeps, you need the right coolant for your vw it is pink in color and some napas have it (Not DEX Cool) and you probably have a coolant leak, usually a plastic flang at rear of cylinder head goes bad
Check coolant level and top off with G12 VW coolant only or filtered water.
If you haven't replaced your water pump, chances are it could be the
original part (OEM). This use a composite material impeller similar to
hard plastic. They are prone to cracking at the shaft connection for
the pulley and doesn't spin with the engine. Replace it with an
aftermarket part which have metal impellers. I'd advice to invest on
replacing your timing belt at this time because the water pump is
behind the belt. Also keep in mind to use G12 only coolant (VW red
coolant), these are phosphate free keeping the system cleaner. Your A/C
when switched on automatically activates the fan to lower engine temp
when the compressor adds extra loads to the engine.
That is your coolant light. When the coolant is cold (car is cold) it is blue for a moment then goes out. When the coolant is too hot, it is red. When it flashes, you are low on coolant. Check the coolant tank level (it is the big ball shaped reservoir) and make sure you are within the operating level (about half way up, there are marks indicating proper level)
fan relay is under the frame on the left by the fans. but most likely the fans themselves have gone bad check the fuse panel on top of the battery see if it is burned or blown fuse this is caused by the fans going from stop to high speed to many times. you will flat 40 or 50 amp flat blade fuse and both fans sorry for bad news
Start with checking your coolant level( only use VW coolant if low). If full, change out your coolant temp sensor. Buy the one from the dealership. The others are ****.
If the light goes out after engine gets alittle warm, this is normal. Since there is no temp guage, VW uses this light to inform that the engine is cold. When that same light flashes red, it means that the coolant is low or the engine is overheating.
From what i read, the flashing temp light means the coolant level is low. Check your coolant reservoir. See this webpage for more information: http://www.newbeetle.org/forums/showthread.php?t=31569&highlight=flashing+temp+light
