The blue temp light indicates that the engine is cold and has not yet come up to optimal running temperature. When the car shut off, were there any warning lights on? It could have overheated, the red temp light would have been on. Is the check engine light on at all?
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
I have a 2001 Beetle, the transmisson seen to have a pause and then engage when driving normaly and it's worst on the hills, after driving a distance it smells some kind of quemical that is not oil or gas, the beeping sound and the engine light on the dashboard goes on when stopping (may be the motor) and the temperature blue light goes on constantly. Are all of this related? to transmission? separate issues? The dealer and 2 other private mecanics don't give a perfect diagnosys they are all the time guessing. What's wrong? please advice.
Not certain, but you may be referring to the blue light that indicates when the water temperature in the cooling system is "cold". It's typically blue when the car first starts, then changes color when the water temperature rises. If the light remains blue the water temperature isn't heating up, and you may want to have the cooling system flushed and checked. Depending upon the cars mileage, it may be time to flush the cooling system anyway.
For general awareness, the outside air temperature sensor is located above the inside mirror. Try to reset the temperature measurement unit:1. Switch engine on.2. Press and hold clock minute (min) and hour (h) buttons simultaneoutly longer than 3 seconds. The display will show new temperature measurement unit.
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.
Hi Lori . Sorry but it sounds like your water pump inpeller (The internal part that circulates the water) has broken off or come lose . But i would recomend changing the cambelt and tensioner as well . Regards VW Audi tech
