hi all the service light has just come on my 1996 850 cd 2.5 10 valve do i need a scanner to reset this as there is no diognostic sockets under the bonnet but there is a socket under the ash tray . the car has just been serviced by me but somone said it comes on every 5000 miles if not reset is this true, also any idea where and what prtice a scanner would cost of needed.

 

It will always come on every 5,000 miles. You need a special tool to reset it.
Search the net for Volvo Service light reset tool.

 

Hope this helps:

RESETTING 5000 MILE SERVICE LAMP ON 1994 + 1995 850

NOTE: This function is for the service reminder lamp, be sure you have performed the proper service such as changing the oil before resetting. If the check engine lamp is illuminated when the car is running, you'll need to have the car looked at by the Volvo dealer for proper diagnosis.

1. Turn on the ignition to the KPII position so the warning lamps on the dash are illuminated. Do not start the car.

2. Open the bonnet of the car and locate Diagnostic test port (A) behind the driver side headlamp.

3. Remove the cover and pull the jumper wire out of the holder in the cover.

4. Insert the jumper into terminal #7, then press button 4 times, wait approximately 5 seconds and the red lamp should glow continuously. You are now in the data reset mode.

5. Press the button 1 time and wait approximately 5 seconds for the lamp to glow again then press the button 5 times. After about 5 seconds the lamp will illuminate again, press the button 1 time and you will see the lamp flash repeatedly for a couple of seconds indicating that the service lamp has been properly reset.

6. If a mistake is made, simply switch the ignition off and back on to reset and start over.

1996 Model (Some of them)
On these models the diagnostic socket is in front of the gear stick. Switch the ignition on. As you look at the speedometer on the dash, beneath it opposite the trip reset button is a rubber plug. Remove the plug and with a thin pointer such as a ball point pen, depress the pin. This will reset the service light.

 

my car has no rubber plug looks like i have to buy a reset tool

 

You may need to buy the tool, yes. I'm sure you can easily find one on eBay.

 

found a reset tool for my volvo £20 think thats about $38 sounds ok cheaper than volvo

 

Thats a decent price go for it.

 

just an update have reset my service light geez it was easy hate to think what volvo charge

 

In my car (SW turbo 95) after initiating the resetting, the LED did not ligh-up. Any suggestion?

 

Does the speedo cluster have a rubber plug in it?
If so remove the rubber plug and with the key on press the button in and that should reset it.

 

The one mentioned by tech is Yazaki (Japanese), and the other is VDO (German).
