I have a vw caddy van 2.0 litre sdi,an recently the orange oil low level warning light has come on,the oil level is fine,I have replaced the oil sensor switch bolted to the engine an still the light stays...


I would recommend that you change the oil sending unit. When the oil sending unit is faulty, or simply clogs up, it will trigger the oil light because the engine is not registering enough oil pressure.
I hope that you have found this information to be useful, and if I can be of any further assistance, please let me know. Thank you for using fixya!

Oil pressure gauge not working and it has low oil level some please explain this to me


A low oil level will cause the gauge not to work or read "low" because the sensor is designed to read pressure of the oil as it travels through the engine. Are you getting a message displayed as well ? I would start by making sure the oil is clean and at the proper level on the dipstick. If the oil level is low make sure you first fill it to the proper level then look for a leak. If the oil level is okay then it is possible the oil pressure sender could be bad. Good luck ?

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

Coolant level low light comes on and coolant level is not low in reserve tank or radiator.


There is a TSB for this problem. Here it is.


Bulletin No.: 04-06-02-007

Date: August 11, 2004

TECHNICAL

Subject:
Low Engine Coolant Level Indicator Always On (Diagnose Low Coolant Level System Operation/Check Sensor for Oil Contamination)

Models:
2000-2002 Buick Century, Regal
2000-2001 Chevrolet Lumina
2000-2002 Chevrolet Impala, Monte Carlo
2000-2002 Pontiac Grand Prix
2000-2002 Oldsmobile Intrigue


Condition

Some customers may comment that the low engine coolant level indicator is always illuminated.


Cause

The cause of this condition may be due to engine oil contaminating the coolant. Possible sources of oil contamination are internal engine leaks, improper service procedures, or the addition of some types of anti-leak additives to the cooling system. Once in the coolant, the oil leaves deposits on the level sensor creating an insulating film. This film results in a false activation of the coolant level indicator.


Correction

Diagnose low coolant level system operation and check the sensor for oil contamination using the procedure listed below.


Important: No coolant supplements should be used in GM cooling systems, other than what is approved and recommended by GM. The use of "aftermarket" over-the-counter sealing and cooling supplements may affect the operation of the low coolant level sensor. Discoloration of the coolant recovery bottle is normal and does not necessarily indicate that coolant contamination is present. Flush cooling system only when instructed by this bulletin.

1. Verify that the coolant is at proper level in the radiator and the coolant recovery bottle. If the coolant is low, add proper amount of 50/50 water and DEX-COOL(R) mixture. If the low coolant light operates properly, diagnose the cooling system for loss of coolant as outlined in SI. DO NOT proceed further with this bulletin.

2. Remove the low coolant level sensor. Refer to Coolant Level Module Replacement in the Engine Cooling sub-section.

3. With the key on, the engine off and the coolant level sensor disconnected from the vehicle wiring harness, observe the low coolant light:


^ Light is on - Chassis wiring or instrument cluster concern. Follow the appropriate diagnostic information in SI.

^ Light is out - Proceed to Step 4.



4. With the key off, connect the coolant level sensor into the vehicle's wiring harness. Connect a ground wire (1) to the battery negative terminal. Using a sharp probe (3) attached to the ground wire, ground the coolant sensor probe (2) as shown in the illustration. Make sure a good contact is made. With the key on and the engine off, observe the low coolant light for at least 15 seconds.


^ Light is on - Replace the low coolant sensor and re-check system operation.

^ Light is out - Proceed to Step 5.


5. Using a small wire brush or emery cloth, polish the low coolant level sensor probe to remove any film or oxidation. The probe should be a bright brass color when finished. Use Brake Parts Cleaner to flush removed deposits from the low coolant sensor probe. Re-install the low coolant sensor into the vehicle and proceed to Step 6.

6. Flush the cooling system and install new DEX-COOL(R) mixture as outlined in the SI. Check the vehicle's warranty history to determine if any engine gasket had recently been changed. If there has not been a recent gasket replacement, locate and repair the source of the engine oil contamination.
