How do you reset the service light on a Renault traffic?

In order to reset the service light you need to have either a stand-alone OBD II or an OBD interface for a PC/laptop and suitable software. The idea behind this is that you will go back to the main dealer to get you car/van serviced. The equipment is available on eBay etc., although it is a bit expensive just to reset your service light. It might be worth your while checking with a local mechanic as they may have equipment to reset it and they won't charge a arm and a leg.

Hope this helps.

AddendumI've found that mechanics charge anywhere from $20 to over $100 just to read the codes. I ended up getting an OBD II off eBay for $55 and it reads the codes and resets the light at the same time. If you choose to go that route, you need to be careful that you get the correct OBD II for your model car.
