Last week it started posting 'Check Coolant/STOP' on the digital display panel. The message is only displayed after a cold start and if the engine is turned off/on, it usually disappears.
I started the car today and in addition to the above, a new message is being annunciated: 'Emissions Workshop!'. The car has lost performance (it's sluggish) but otherwise sounds and drives normally.
I plan to have it looked at by a professional asap. What might be causing these errors? Could it be sensor related?
Thanks, Jez
