I have a 2003 ML 350 and the oil light on the dash came on, I had the oil changed and the light is coming on again. I was told it needs a oil pressure switch. Does anyone know it that is possible and what the cost should be to replace it.

It can be the oil pressure switch or the oil level sensor or both. The pressure sensor is the easier to get at and cheaper labour while the level sensor means the oil pan needs to be dropped. If you can do it yourself you can save a bundle on this repair. Any independent shop should be able to do either repair so you won't have to go broke at the Mb dealer so you have lots of options on this.

Hello, yup sounds like the oil level/quality sensor is bad. Its not a hard fix, raise the engine and remove the lower oil pan, then 4 bolts and the sensor is out. Its a common issue and I guess around $500 parts and labor, again that's a guess. Cheers!

SOURCE: Resetting Oil Service indicator lights on 1995 e300d mercedes

Hi Mike,
I'm in the U.K. and your Quarts are of a different measure to ours, I would say that is about the right amount, however careful topping up on level ground and monitoring the dip stick should get you there? anyhow where you bought the oil will have capacity details.
As for oil service light have you tried holding down the trip reset button whilst turning on ignition? Keep it pressed for about 10/15 seconds.
Good Luck!
Press the Blue button please if helped by my FREE Effort, Thank You!

Its on the screen - if I remember correctly, you go to the Nav menu and you'll see a "main menu" button (it may say "settings") on right hand side (forgive me I am doing this from memory)... press the button, it will give you the "set clock" option; select daylight savings time or whatever corrects your settings and it will move the hands automatically

Check first the condition of the oil. It may be low or need replacing. When you do replace the oil include the filter as well.

I would suggest to have a scanner connected first to the car to help you accurately diagnose the problem. Some shops would let you borrow their scanners or have your car scanned for free. This is the best way to avoid unnecessary expenses for repair.

Usual cause of failure other than bad fluid are, velocity sensors that may have gone bad. A dirty or bad solenoid in the transmission and debris in the gear valve of the transmission. Other errors may cause you to be limited at certain speed and engine condition for safety reasons which may lead us back to identifying first the possible error stored at the car's computer.

  • When you get a message that says "wait" it is because the wrong code was entered incorrectly. Each time the word "wait" appears the wait is a little longer. The radio must be on during this "wait" time. When it goes away then enter the code correctly and you will have no problems.


  • Hope this helps.

AFTER OIL CHANGE MY ML350 OIL HI LIGHT IS ON AND WHITE SMOKE IS COMING FROM THE EXHAUST

They may have added too much oil -- a 2004 MB ml350 with a 3.7L engine should take only 8.5 Quarts (including what goes in the oil filter) -- Exactly 8.5 Quarts, no more, no less. You may be able do check the oil level by using the onboard computer - pushing the buttons on the steering wheel - follow the directions in the owners manual on how to check the oil level.

Toyota dyna oil light reset

After changing the oil and filter on a 2008 Dyna, the "oil change" light would not turn off. On the plastic dash screen, there is a small circular rubber plug just above the rev counter. This plug can be prised off. Prise off the plug, insert a pin and press the button. Oil change light turns off.

A week ago my 2003 CRV suddenly had the check engine light on, then stalled at stops on the way home. I took it to a Honda dealer who ran the codes. I was told the oil was low (1300 miles after the last...

THAT PARTICULAR CODE IS CAUSED BY A CATALYTIC CONVERTER DEFECT. YOUR OIL BEING LOW SOUNDS MORE LIKE IT COULD BUT MAY NOT POSSIBLY BE YOUR STALLING PROBLEM. IF THE CAT IS STARTING TO GET CLOGGED U WILL START TO GET STALLING MORE ON THE ACCELERATOR THEN OFF. YOUR BACKPRESSURE FROM THE ENGINE NEEDS TO BE CHECKED. THEY SHOULD HAVE NEVER LET U TAKE THE VEHICLE HOME WITHOUT FINDING THE SOURCE OF YOUR OIL LEAK. THE ONLY FLUID ON THIS EARTH THAT DISAPPEARS OVER TIME IS WATER. YOUR OIL IS GOING SOMEWHERE AND IT NEEDS TO BE FIXED. SORRY TO SAY BUT U HAVE MORE THAN ONE PROBLEM. THE CATALYTIC CONVERTER ISSUE NEEDS TO BE FIXED AND YOUR OIL LEAK FOUND. SOME OF THESE DEALERS ARE CROOKS. IF YOUR CAR IS STILL STALLING ALWAYS TRY TO GO BASIC FIRST SOME OF THE SIMPLEST THINGS COULD BE CAUSING YOUR STALLING.

On 2003 Buick Century had the oil changed but the change oil light comes on when I first start the car and stays on for about 3-5 min. Is it supposed to do that or does it need to be reset?

It just needs to be reset. Turn the key on with the engine off fully depress the accelerator three times. The dash should say "engine oil life reset" if done correctly.
