2006 Volvo S40 - Answered Questions & Fixed issues

You can only check in hidden menu which modules have some errors (DTCs). Then you need to visit your Volvo dealer.

maybe the brakes are dragging? check for a hot wheel when you stop

Not familiar with volvo but had a pontiac years ago that had a shift up/down light that was only to maximize fuel economy (standard transmission)

Just here and there , you hear a "click" while a.c is on... Ok, turn the a.c off , see if the "click" disappear's ??.if so... I,m guessing it's the a.c compressor clutch kicking in and out of the system as it is required to do. turn the a.c off , if not , you need someone in person to search out the "click" , past that ... turn the music back up and cruz !! , lol... good luck !!!!

Well, did you do the next thing and check for spark? Coil?

If the clutch is engaging while you are pressing the pedal and you are losing fluid either the clutch master cylinder or the clutch slave cylinder is bad. If the fluid is leaking from the firewall on the drivers side its the clutch master cylinder. If the fluid is leaking from the transmission area its the slave cylinder.

Mode actuator bad

Volvo stopped using Gear to Gear Timing when they switched to the B23 Engine and have used Belt Timing ever since.

Use a small electric heater on low with the windows barely cracked open.

It means you need to get it scanned. Foxwell NT 300 Diagnostic Scan Tool

Yes

Should be a test port with a cap on it on the fuel rail. Remove the cap and there should be a valve like a tire valve in it. Put on eye protection and depress the valve with a pocket screw driver. Then cycle the key and do it again until you have fuel and no air. Do not do this if the engine is hot or there is an ignition source close by. Have a fire extinguisher available.

You need to have your problem fixed, if already fixed and engine still stays on then, you need to have the error code deleted on the ECU (electronic computer unit). You can do this with a ODB port reader if you have one or have it done in a workshop.

try turning the key the opposite way when locking or it could be the power cable is not connected or broken

You can check fuses, but most common issue is the microswitch in the trunk that need to be replaced.

Remove door handle, you will find some screw under there, some on the bottom of the door trim. Mostly it's hanging on clip-ons.

Try this procedure. It works on some models.

1: Turn key to position #1
2: Push, and "HOLD" the Trip Reset button.
3: After 2 seconds, keep holding the trip reset while turning the ignition switch to position #2.
4: Keep holding the trip reset button in for about 15 seconds, the amber triangle in the dash should start flashing. Release the trip reset button when it does. Turn ignition off, on, then back off.

If that doesn't do it, you may have to see a dealer. Good luck.

Hi,
I've reset this particular model I held down tripmeter button turned on ignition whilst still holding it down for 20 seconds at least then Bingo sorted.
If unsure hold all buttons on speedo face down.
Good Luck!
