From memory when mine displayed the 'emmission service required' message it was just that and an orange check engine light - the car didn't go into limp mode as such. I don't remember it mentioning anything about the engine either. If it is the emission service it's a fairly common one and the warning can be switched off via a cheap OBD code reader and the torque app or similar (that's how I did mine), however anything other than that you should definitely get checked out!

Really need the PCodes to understand fault.
£20 scan tool from Halfords plugged into engine diagnostic connector (drivers footwell, plug closest to steering column) and list out the series of PCodes. But a limp mode is usually throttle pedal or throttle body related.

Thank you Dr. Steven.

I am greatly relieved now, but how did that happen?

Just to add my experience to this.

I had the yellow emissions warning a few times, on and off over 4 months. When it's just the yellow warning, occasionally - it's time to get the code reader and see what's going on.

I bought an ODBII reader for £4 from ebay, which pairs with your phone and that was able to to read and reset the codes just fine.

After another couple of months, the warning light came on more consistently, so pretty much every day, but again, easily cleared from my ODB reader paired to my phone.

At this stage, the warnings went from yellow to red, I got the same warning as the OP. When the red warning was on, I was running on 7 cylinders, so I would stop the car, pause for a moment, and restart. Oddly the red warning completely disappears after a restart, no ODB reader required

In my case - it was simply the two front O2 senors which were faulty. I found NGK replacements (again on ebay) for £52 each, and my local superb Aston garage fitted them for me.
