[Kev0607]

If I recall correctly & the car is due a service, the dash warning says something along the lines of "Scheduled maintenance due".

I think the error you're getting now would be "Engine System Service required", not "Engine Service required" - The latter isn't a warning that pops up to my knowledge. If that's the case, the message isn't telling you that your car is due for an oil change etc - Its indicating an engine system error.
