Default 98 New Beetle flashing blue cooling system light

hi, this is our first VW, just bought it with 87k miles. drives great, but it intermittently displays a flashing blue cooling system light. the manual says it could be low coolant or a malfunction. the coolant level seemed high, so i drained some off to the max level. the light goes out when the accelerator is pressed and flashes again at idle.
also, i noticed lots of old coolant dried up (pink paste like) on top of the transmission housing, with some more liquid type fluid (still old looking laying deep down there). i can find no evidence of recent leaks, but i am just learning may way around the engine compartment.
lastly, there is either oil or trans fluid leaking in small amts (hard to tell just what it is or where it is coming from). do these cars have any noted problems with seals i should check?
thanks much, this is a great car which my daughters will enjoy driving.

Hi! You likely have a bad coolant tempature sensor if your fluid level is inbetween min and max; or a bad sender in the tank. It's a $6 part.

I know my buddy with a 98 said his whole coolant system just deteriated... all the plastic hoses and the like. He had it all replaced over time at about 80-90k, if I recall right. So the residue could be leftover; if you don't see any new it's pretty safe to assume they've replaced the hoses (but you can look and tell how worn they are yourself, too). The obvious one is a lose bolt on the oil pan; park the car on a tarp and catch a sample.. you can basically look/smell and tell if it's trans fluid or motor oil. I would suggest replacing the auto trans pan and auto trans fluid... dealers will say that it's not necessary; but it is. DO NOT flush the system!! Good luck!

Default follow up question

thanks for the reply. i will order a new sensor i guess via an online source. not clear on the transmission recommendation and oil line situation. you suggest not flushing transmission, but rather to drop the pan, replace the filter, install a new pan and top off the fluid? just curious, why not flush the trans?
also, i did notice the lower radiator hose seems a bit soggy right under the oil filter area, where oil has dripped down during changes. i will replace that hose. by doing so, do i need to remove air from the radiator after i replace the hose or will it naturally purge itself?
thanks for the advice.
