Error message
 

Just had my 2008 V70 estate serviced & now I've got an error message: "Engine System Service Required".
Questions: What does it specifically refer to as surely it shouldn't appear just after a service (last Thursday)? Is it safe to drive it with this message showing?

I think this needs to be reset using Volvo diagnostic tools, (main dealer job) but it's just to tell you it's overdue for a service, nothing to worry about, mine was on for ages...
Also you may get better answers if you repost in the section for later models.
