I don't think it's related but have you topped up the oil?

    I don't know what they charge per scanning but at least you'll know what is wrong with your car. You could try removing the battery terminal for 10 minutes abd then refitting if and letting the car idling for 10 minutes and see whether the check engine light goes off.

    Let us know how you get on.

    Cheers.

How to read oil filler levels


Hi Dave the capacity varies from vehicle to vehicle. If it has a dipstick there is two marks on it a about 1.5 inches apart, the one near the end of the stick is the mimum level, and the one higher up is the maximum level. If you are changing the oil drain and refill with 4 litres or 2 quarts. Then check the level if its below minium add around 1 litre and keep checking until the the level is at least between the two marks. Regards Jim...

After filling up petrol to the brim the yellow malfunction light came on and it was computer checked.After three bottles of fuel treatment the warning light comes on and off. Service manager informed that...


Filling to the brim is not recommended. North American (possibly European cars also) cars have a charcoal (carbon) canister in the pollution control system to filter fuel vapour. Overfilling will cause this canister to also fill with liquid fuel when it is meant for vapours only. When refueling in the future, do not top up to the brim, but stop when the nozzle automatically shuts off the flow. Driving for several tankfuls may purge the liquid fuel from the canister and solve the problem. You may need to reset the OBDII (On Board Diagnostics) system to verify and clear the fault code. OBDII readers/resetters can be purchased for as little as $50, or get your dealer/mechanic to do it.

Hi there,

An orange warning light which is a picture of an engine = Engine Check Light. Most commonly known as the Malfunction Warning Light (MIL).

If this light illuminates while driving, it means your engine computer has detected a malfunction somewhere within the vehicle's electronics. The computer monitors hundreds of components & circuits. Some of these are critical in nature.

For this reason, it's important you make arrangements to have an authorised Toyota service agent (or Auto Electrician) scan your vehicle's computer for diagnostic codes. This process takes only 15mins or so. If you have an Autozone nearby, they sometimes do this for free, otherwise find a service agent who can do this check for you, at little cost.

I have a 2005 kia sorento and a light came on today next to the fuel it is yellow im not sure what the light means


There are many yellow lights on vehicles. They can be different on the same make and model of any particular vehicle depending on what option packages your vehicle is equipped with. Your best bet is to look it up in your owners manual. If you do not have an owners manual, I offer this advise: On all vehicles with the warning lamps in the instrument cluster, the yellow lamp are advisory lamps. ie. telling you that there is a malfunction with a system or letting you know that certain systems have been disabled. It is usually safe to operate the vehicle with the yellow warning lamps illuminated long enough to get the vehicle to a repair facility. (Check Engine Lights, Airbag Lights, Low washer Fluid Lights, etc.)The red lamps on the other hand, mean that the vehicle is not safe to drive before the cause of the lamp coming on has been resolved. (examples are the red Brake Warning Lamp, The Engine Teperature Warning Lamp, The Oil Pressure Warning Lamp.)
Since you stated the the lamp is yellow, I would say that it would be safe to drive the car to your local repair facility and ask them about it and get a professional opinion of what to do about it.

Yellow light on dash with flashing exclamation point inside it, what does this mean?


Hi !
The Yellow Exclamation Point is the indicator of malfunction in the Power Steering system.
1. Check the Tension of the Power steering Belt.
2. Check Oil level of Power steering , this must be below MIN level.
This is in a white bottle next to Break fluid.

Cannot find the oil dipstick on my renault kangoo


2002 Kangoo Trekka 1.6 16v petrol dipstick.
Open the bonnet, go to the drivers side front wing and look down to the front of the engine. You should be able to see the oil filter at the front of the engine.

With the engine cold put your hand on the oil filter and the dipstick is just over a hands width towards the front centre of the engine.
Also where it says 16 valve in yellow on the top of the engine cover follow a straight line down towards the front of the engine and that's pretty much about it's location.

When the "oil ok" light is displayed on the dashboard, press the trip reset button there should be six 000000's displayed.

This lets you know if the engine oil is at the correct level.
These zeros decrease as the oil level goes down. I reckon It's about 250mill - 1/4 of a litre of oil for each zero.
So let's say if you have only three zeros displayed, then you would require about 750mill of oil to reach the correct level. It's best to add a small amount at a time using a measuring jug.

Hope this helps,

Ian.

Lacetti Chevrolet. Malfunction Indicator light is on.


It may be the same problem as my 56 plate Lacetti. The yellow malfunction light came on two weeks ago and two days ago, both times shortly after filling up with petrol to the brim, and I suspect it is the petrol sensor as I only clicked the petrol cap once after fitting it back - the handbook says click it several times. The yellow light also came on yesterday after taking the car a short journey so it is likely that the sensor is still picking up a small escape of petrol, but the car has been fine today with no light appearing now that the fuel level has dropped a bit. Like you, I have not noticed any drop in power with the light on.

Inspection light on


The green bar is the service indicator bar. The bar shoulld decrease every 1500/2000 km to indicate still how far you can drive before the next service. It will evetually change to yellow and then red. This means the service is overdue. When my 1995 318 went for a service the dealer reset the indicators to full green bars. A week later the bar was in the red. Some computers are prone to this fault due to low ore loss of battery power. Just make sure the physical km of your inspection is still maintained. BMW SERVICE RESET Take a small wire, paperclip, or elect wire and bend like a horseshoe. No light or equipment necessary Open the diagnostic data port, the one were the little pacman centre is located. Turn the ignition to position 2, don?t start. Connect pin7 always first and then pin 19. Hold for 4 seconds. Remove wire and settings will be reset. Warning if you hold the wire longer than 10 seconds you may reset inspection intervals 1 and 2. I?ve done this twice and it definitely work on my E36
