What is the warning when the gauge looking like a little engine, between the battery and oil gauge is on?

forgot to say temp gauge jumped UP, and is way too hot
and the overflow bottle is empty (and eng. oil is too thin to hot) _
heater dead, means engine coolant is mostly gone
let engine cool fully,
rad cap off, see rad is super low or empty, so put in 50% AF and top if all off, then run engine only in drive say, do not drive it until repaired.
cap back only idle engine for up to 1/2 hour to get 180f temps.
the thermostat may be bad, it is too old that old..
after idlng , look for leaks to ground, to cab foot wells (heater core leaks) and leaks to oil pan. (oil looks like chocolate milk)
see steam at end of tail pipe< bad that on a fully hot engine.
that is the tip of the ice berg, we do tests based on what seen above.
and serial process of tesst. and I uses RAD leak down tester.

This vehicle won't have an amp gauge but might have a volt meter. A battery should have about 13 to 14.5 volts present when the engine is running and the alternator is working properly. Fair warning: the gauges are notoriously inaccurate so the best way to check the charging system is at the battery terminals using a simple good old fashioned hand held voltmeter. A fully charged battery, with the engine off, has 12.6 volts. If you have only that amount of voltage or less with the engine running then you have a charging system issue.

Engine would be very noisy, oil pressure gauge would show little or no pressure, warning light (if any) would be on about engine or oil.

Sounds like a bearing starting to go somewhere in the driveline; assuming the differential and transfer case are full. As to the oil pressure; If you have the correct weight of oil in the engine and it has been changed on schedule; the higher the better.

I Would Say It Means Automatic Transmission Fluid Is Hot ,So Check Its Level There should Be a Dip Stick For This If Not Then i Would Think something Is Wrong in The Gear box Or The Gearbox Oil Cooler If Fitted Could be An Integral Part Of The Radiator.

Could be a few things, first Get it checked with a mechanical gauge to test low motor oil, clogged oil filter, bad oil pump, clogged oil sump (pick up tube) or bad oil sending unit. Then replace sending unit sensor.

First, do not keep driving if the oil warning light is on or your oil pressure gauge has dropped. Stop the engine, let it sit for a few minutes, then check the oil level.
Don't ignore it. An oil pressure warning light (or low gauge reading) means one of two things: either your engine has dangerously low oil pressure, or the oil pressure sending unit that triggers the warning light (or operates your gauge) has failed. I hope this helps.

If you put too much oil in an engine it will exert excessive pressure on the oil pump which can lead to pump failure and/or failure of engine seals. I am not very familiar with Audi/VW but the warning light could mean not enough or too much oil in the system. Start the car and let it run for about 15 to 20 seconds then turn it off and check the oil level. If the level is over the fill line you will need to drain some of the oil. As odd as it sounds it is better to have too little oil in the engine than too much. PLease rate me on this answer.

It's not good news when there's engine oil and coolant in the same sentence. Don't drive it anymore and have it looked at by a trusted mechanic. Good Luck.

I have a 2000 polo with the following service alarm SERVICE OIL The oil has been topped up but the service message still remains
