WHAT'S THE DIFFICULTY IN SWAPPING MY OLD VVT VALVE WITH A NEW ONE
Very easy to swap the vvt valve,but that will not guarantee to rectify the problem,more than likely it will be the vvt pulley/timing unit,this will involve the timing belt coming off.
The vvt valve is located under the upper timing cover,remove the cover and you will see the valve situated on top of the head,undo the connector and remove the 4 bolts and the valve will come off,alittle bit of oil will come out on removal.
remove gasket and ensure the area is clean.
Re-fitting is opposite procedure,ensure a new gasket is fitted.
Hope this helps

I need an assembly diagram for the trunk lock assembly from a 2001 volvo S40. THe trunk wouldn't open, so I pulled the lock assembly out. I found which bit was broken, but I don't know what the piece looked like originally.
My son was missing with the valet parking key while I was driving. When we got home and tried to open the trunk it wouldn't. It also made this buzzing sound when I push on the trunk latch.

trouble code P0015 (camshaft position actuator, timming overretarded bank 1) How do I find and repair the problem?
This is a common issue particularly with vehicles that have had some neglect to the oil change routine. The VVT solenoid on the top of the valve cover gets clogged with thickened or sludged oil.
Replace the VVT solenoid and gasket with a new unit and clear the codes.

Hi,I bought my car with only one set of car keys, it usually comes with 2 keys and a remote to lock/unlock. I called the volvo dealer they said I need to pay $225 for the key and another $225 for the remote. Any idea if I bought another S40 remote if I can program it myself or I still need to take it to the dealership. Also concerning the key, where can I find the key code so the keysmith can make me another key. Thanks...
You car has an integrated key and remote.
There is a software that needs to be downloaded to the car. When the
remote is purchased at the dealer it comes in a plastic package. That
plastic package has a sticker on it. The sticker contains id codes.
There are two codes one is 16 digits/letters and the second one is 8 digits/letters.
Without this sticker the dealership can not program the remote/key to
the car. If you buy a key elsewhere, make sure it has the codes included.
Unfortunately you cannot program a remote yourself.
