2000 vw beetle 2.0 L, low level coolant light...engine mil code 1256

Shortly after blue water temp light goes out and engine beginds to warm up, red blinking low coolant level light comes on. Shortly thereafter coolant expands and over flows from expansion tank. Does not show overheat light. Changed thermostat,coolant expansion tank, and coolant temp sensor. Added compatible coolant. Still have blinking low coolant level light. What next, water pump even though it shows flow from the top hose of the expansion tank????

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

SOURCE: overheating problem

water pump. water pump. water pump. i am a vw dealer tech and on 2.0 and 1.8t beetles the water pump impeller is plastic, and what happens is usually another component, fans, fan control module (under battery tray), thermostat, fails and because the impeller is plastic with just one overheat the plastic becomes brittle and shatters, pull the water pump out and you will see the impeller in 3 or 4 pieces. replace water pump and make sure t stat opens, fans come on (a/c off) and proper water pump flow.

SOURCE: OVER HEATING

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

SOURCE: overheating problem

looks like you have done everything but the problem with your car is that the cylider head gasket has gone have a look at the dipstick or remove the oil filler cap if it looks like mayo then 100% head gasket has failed you said no water on the floor so it must have gone into engine only way this can happen is head gasket failing, if you have put lot of water in to the cooling system then your sump will be full of oil water mix.

let us know your findings so we can help you more if you need it

The hose is an over flow drain. If you've seen no signs of leaks then most likely your radiator cap is bad. The cap helps to pressurize the cooling system, if it is bad it allows to much coolant out to the over flow tank and the extra is dumped while your driving. When you turn off your engine the fluid is drawn back into the radiator and your coolant mysteriously disappears.

I have a 2000 VW Beetle, the blue temperature light is on all the time, it is kangerooing with no acceleration when cold, nothing shows up on the code reader any ideas Laura


There are probably two coolant temp sensors--one for the dash display and one for the ECU to do fuel trim. Unlikely that both have failed at same time, but possible. First, insure coolant thermostat is not stuck open preventing normal warm up, then test or replace coolant temp sensor for the ECU.

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

Temperature light flashes red and beeps when first turn on car after a couple blocks - goes off


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.

2003 Volkswagon beetle temp light is red. (Usually starts out blue and then goes out when the engine warms up.)


A red light indicator may signify a hotter temperature, but may not necessarily indicate an overheating condition. A couple things can lead to this condition - low fluid level (check the fluid resevoir), the wrong coolant being used previously, a weak or failing water pump, a plugged or partially plugged coolant radiator, a bad fan, or a bad thermostat. I'd personally check the coolant first, usually needs to be replaced at about 100,000 miles or so, then check to see if you have any leaks if the fluid level is depressed. Then allow the car to operate from a cold start in the drive while observing the performance under the hood and compare it to the dummy light.

Hope this helps.

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:
