Thank you for your question. Please try the following.
With Ignition OffHold Trip Reset In (keep held in)Turn on IgnitionStill Hold Trip Reset for approx 12 seconds, the service light should change.release trip reset.switch off ignitionswitch on ignition and check.
This should remove the service light. If not please get back to me and I will advise further.
Ok, I'll check at work and let you know later.
Hi again Neil.
I have spoken to a colleague who used to work for a Vauxhall dealer. He states that the method that I have given you is correct. However, he also says that the service light can illuminate if the ECU has a fault code stored, so it sounds like this is what has happened. You will need to have a diagnostic check done to see if a code is stored.
I'm sorry if this is not what you wanted to hear.
