SOURCE: Porsche 944 S2 inaccurate petrol gauge reading and oil level warning light

This is not a known solution, but in general these cars suffer from voltage and current drops on electrical connections due to corrosion on contact surfaces. I cannot remember the number of times I have read about electrical problems on these cars, and the problem was usually solved by cleaning the electrical contacts or replacing a relay going bad (BTW, this car does use a lot of relays however I doubt there is one in the fuel gauge circuit).

Also, I have a spare gauge cluster for the 944 and when I look at it, there are some resistors on the "printed circuit" piece. If one of those were to lose tolerance, or burn open, it would no doubt have an effect on the accuracy of the circuit. I would check out that circuitry and test the resistor values as a last resort -- it is not likely the gauge itself if it is working at all. However, before doing that I would clean the electrical contacts thoroughly. I have not tried to gain access to the wiring harnesses for the gauge cluster while it is in the car, but I doubt it is possible. So, if you have exhausted all other ideas go to the Clark's Garage site for instructions on how to remove the dash, and just follow the portion that applies to removing the gauge cluster. Go to the local electronics hobbyist store, or online, and obtain a good contact cleaner and clean all of the electrical contacts while also looking for loose or broken wires. NOTE: Be careful and gentle dealing with the plastic connectors on these cars as they tend to be brittle and little tabs break off easily if man-handled. Go slow, be in the right frame of mind and use good lighting so that you can see what you are doing.

Dip stick shows no oil. No warning lights on at all. Oil pressure is good according to gauge.. car runs fine. What do I do?

hello,do be very careful,as without oil,you will destroy your engine within a minute or less! get some one to re-check your dipstick,is it the correct one for your car?leave engine off for a few minutes,make sure your vehicle is on level surface and not uphill or downhill ! it could be that your dipstick is exceptionally dirty,or your engine oil\'s exceptionally clean (new,and recently changed)that you are unable to discern accurately the presence or the level to any reasonable degree,get a local garage to do a pressure check with an auxiallary gauge to asess the real answer to this mystery.hope this helps,regards.

Light

This is the "Low Oil Pressure Warning" light. It is RED for a reason! When this light (or any RED warning light for that matter) comes on, pull over and shut the engine OFF at once. Allowing the engine to run with insufficient oil pressure can cause a catastrophic failure in mere seconds. Such a failure can cost thousands of dollars to repair.
This warning is most often the result of a very low oil level as indicated when checking on the oil dipstick. The engine oil level should be maintained as close to the "full" mark as possible - without exceeding it. Oil should never be allowed to drop below the "low" mark on the dipstick. If the oil level is shown to be between full and low, the light is probably coming on as a result of a faulty oil pump (the oil level should be checked with the vehicle parked on level ground, with the engine OFF). A faulty oil pump is unable to pump the oil with enough pressure to reach all the moving parts of the engine that require lubrication. Without proper lubrication, connected moving parts heat up, expand and seize. Moving parts are expected to move - not be prevented from moving.
If your engine shut down, it may be the result of some of the internal parts seizing. Hopefully, this is not the case. Check the oil level and top off as needed to bring the level up and attempt to start the engine and have the vehicle checked by a trusted mechanic.
Good luck!

How do i check a volvo 850 turbo's transmission fluid? do i have engine running? off? in park or neutral? thanks

Check the oil level as follows:

Park the car on a level surface with the engine idling . Slowly move the gear selector lever through all the shift positions and then to position P. Wait 3 minutes before checking the oil level.
As the illustration shows, the dipstick has a COLD and a HOT side. The oil level should between the MIN and MAX marks. Wipe the dipstick with a clean cloth.

WARNING! The oil may be very hot.



Do not use rags that could leave lint on the dipstick. The transmission is topped up via the dipstick tube. The space between the MIN and MAX marks on the dipstick corresponds to 0.5 US qt. (0.5 liter). Do not fill the transmission with too much oil, since this can result in oil being ejected from the transmission. Too little oil, on the other hand, can negatively affect transmission operation, particularly in very cold weather.

A Cold transmission: oil temperature 105° F (40° C). This is a normal temperature for the transmission after idling for about 10 minutes. At oil temperatures below 105° F (40° C), the level may be below the MIN mark.
B Warm transmission: oil temperature 169° F (80° C). This temperature after driving for about 30 minutes. At oil temperatures above 190° F (90° C), the level may be above the MAX mark.

Fluid type: ATF Dexron IIE and Mercon.

Oil press. stop motor is written on the dash. I'm due for a oil change...is it dangerous to drive my car with this notice?

yes, you are in danger of ruining your motor.. check your oil by pulling out the dipstick, wiping the oil of the end of the dipstick and replace it fully down again into the dipstick tube. Pull it out again and check the level of the oil. If it is low, add oil before driving. If it does not show on the dipstick, add 1 quart at time and check the level each time before adding more, until it is to the correct level marked in the dipstick

How do you check transmission fluid

Make sure the engine has been at operating tempurature for at least 5 minutes. Open the hood and locate the TRANSMISSION dipstick, this one is different from the ENGINE OIL dipstick. It is usually bigger and located closer to the firewall in the engine compartment, if you have any doubts about finding it, look in your owners manual, it should tell you where it is. When you pull the correct dipstick you can tell becuase the fluid is RED and not BLACK or BROWN like engine oil. The car should be on a level surface and the engine should be idling in PARK to check the fluid correctly. Pull the dipstick, wipe it with a clean cloth and then re-insert it and pull it out again. There should be clear markings on the end of the dipstick to show where the level is. Again, check in your owners manual to see where normal levels are marked. If you don't have an owners manual, just look to see if the level is at least between two marks; an uppper and a lower. If no fluid shows on the stick, you are running low on fluid and could damage the transmission, have it filled immediately.
Hope this helps.

Where is the oil dipstick on a 2003 E Class

The 2003 e-class doesn't have an oil dipstick. Engine oil level is gauged electronically. Park the vehicle on level ground and cycle through the display using the buttons on the steering wheel. One of the options there will assist with the correct oil level and let you know if it's ok, too much or too little. Do note that there is an oil filler tube with a cap but this is really for filling the oil as well as removal with a vacuum suction tool in the work shop. The cap doesn't have a dipstick at the end.

How much New oil should i put in to my 1992 Suzuki Sierra 4x4 Cheers Neil B

First make sure your drain plug and filter are installed and tight, then add 2 liters of oil and check to see if there is any showing on the dipstick. Add one liter at a time and recheck the dipstick. Bring the level up to the full mark on the dipstick. Now start the engine and observe the oil light(turn off) or pressure gauge(pressure goes up) then turn off engine. If neither happens after about 10 seconds, shut off engine and check for leaks or other malfunctions. If all is O.K. then recheck oil level on dipstick. It should be somewhere between the upper and lower level, usually indicated by crosshatch marking. Add oil to bring oil level to full mark. Small amount at a time. Most small vehicles only take about 3.5 to 4 liters.

Flashig oil light

You either have a loose/worn engine bearing or a worn out oil pump, do not drive the car this way, you will cause serious damage to the whole engine. A oil switch is for a light, it turns on the light when oil pressure falls below about 10 PSI, a sending unit is for a guage that shows oil pressure with a scale, it may have numbers on the guage or just green and red, or high and low.
