Please check CEM (module with fuses and relays) because sometimes connections get loose and cause those issues.

Have you checked the front wheel balancing?

If Volvo customer service deny there is a recall it is possibly something that has been misreported or misunderstood or perhaps it doesn't apply to vehicles in your country or region. If in doubt I suggest you contact a motoring forum or a motoring organisation or any big newspaper or magazine with interests in consumer rights and/or motoring.

The service indicator can be reset as follows: Place the key in position 1, push and hold the trip odometer reset, the trip odometer will zero, turn the key to position 2 while continuing to hold the trip odometer reset. The odometer number will return to the previous value and the service indicator will be reset.

There was no slatted cover on my S40,the slatted cover on yours sounds like a custom filter put there to prevent any foreign object from falling into the engine space, don't remove it . If you do remove it remember to put it back

Hi Samantha go to someone and get it diagnosed it will cost a fortune otherwise. It's likely to be the fuel pump or filter. The pump can be tested easy enough. Regards Jim...

replace the fuse,or the switch

Press and hold trip reset button until you'll see code of this message. Most common it's 019 - "Engine service required".

Which one? There is one at the front of the engine by the timing belt, one at either end of the cross member that runs from under the radiator to the base of the fire wall and one at the rear of the transmission. I have had to replace all of them on my 2000 S40

Ignition timing is controlled by the engine management computer and is not adjustable. Valve timing is set at a fixed position when the timing belt is replaced and not adjustable.

There is no "map". Crawl under the car and in the center you will se a bar/cross member that runs front to back. There is a mount towards the front and another at the rear. You will need a flashlight and a prybar. Pry up on each mount and look for cracks/splits in the rubber. You usually need both because when one goes bad the other takes all the torque and splits.

What year is it?

You may have triggered the immobilizer when the battery got hooked back up. Try cycling the key in the driver side door lock a couple of times and try it again.

No pattern of failure with this item. Check fuses first. Then you would need to check for power from the switch and thru to the motor.

The engine control module (ECM) checks the signal from the by-pass valve in the thermostat housing. The diagnostic trouble code (DTC) is stored if the signal from the by-pass valve is too high. The fault is diagnosed by the engine control module (ECM) when the ignition is on. Check for short-circuit to supply voltage in the signal cable.
