Check Engine Light Problems S40 2002

The only place to go is to the dealer, the software should be somewhat cheap. I would guess around 100.00

Before you follow up on the software, check if the thermostat is working. The engine should reach normal operating temp (middle of the guage) at idle. Then drive down the road, the guage should remain in the same position. If if falls to the left, then replace the thermostat. If it remains constant do the software.
