The clip is the key. It should be on the side closest to the windshield. Simply grab the tip firmly between thumb and two fingers and lift straight up. You will probably think you are breaking it but it should just snap off...reverse the process to replace clip.

P0118 is an OBD II (on board diagnostic) generic code. It's explained as :

P0118 - Engine Coolant Temperature Circuit, High Input.

Hi yes you can run your car on bio diesel and it doesn't affect the performance of the car. we have a Volvo v40 1999 & v40 2001 running on 100% bio diesel.

But you will have change your fuel filter once you have done 200 miles which cost about £7 for replacement part and take 10 mins to change and you can use a oil filtyer remover tool to get it off. it is located under the bonnet on the passengers side at the back at the botttom screwed on side ways and it sshould be white in colour. as the bio diesel will break down the residue left from normal diesel in the fuel filter which could block the fuel pipes and injectors.

That's all you will need todo to run your car on 100% bio diesel.

Hope this helps

You need to look up codes using a scan tool, or better yet VIDA.

how do you change aligment the exaust canshaft on a volvo v 40

A check engine light displaying on a Volvo V40 means maintenance is needed on the car. Check the car's instruction manuals to see each mileage checkup recommended by the manufacturer.Ê

under the seat look for the plug and un plug it

no idea whats wrong but mine does the same.... it might be the clutch or the gear box.... took mine to a Volvo dealer.. they fixed something but it still broke down again on the way home... not sure they know what they are doing.. do you have any more info ??

Mode 6 is away to find misfires before a check engine light comes on. Useful mostly for Ford vehicles because not all manufacturers fully support this yet.

Hi All, I have a V40 Esate and having followed all the owners manual procedures getting nowhere was informed by the local dealership that the lights can only be turned off by them as it is a software issue and has to be limked to the Volvo manufacturers to comply with their regulations. Hope this helps, Barry

With the ignition off, press and hold in the reset button for the trip odometer, then turn the ignition on. Hold the trip odometer reset button until the service reminder indicator starts flashing (about 10 seconds). Release the reset button for the trip odometer within 4 seconds.

There's a screw down clamp on the front that secures the base of the battery. Unscrew that all the way and remove. Should come right out. Insert clamp over new battery's base on front and torque it down. Should not take more than 10 minutes.
