2 Months and 4000 miles on, when switching the engine off this afternoon I got my first 'Engine Performance Reduced' message in the display.

I had just driven 20-odd miles without a hitch, and sure as eggs is eggs, when I switched it back on, no message and no reduced performance to boot.

Is this a typical electrical gremlin on these cars? I've had other Marques that throw a wobbly periodically, so it doesn't concern me too much....just wondered if it's a common issue, and whether or not it would store a fault code off the back of it?

Any input gratefully received.  Foraging near Gaydon....

MY13 HSE Lux SD4, Baltic Blue - current, 30,000> miles without fault
MY12 HSE 2.2 SD4, Sumatra Black - gone after 10 months/43,000 fault-free miles

Hard to say if it will throw up a fault code but hay, I wouldnt worry to much about it unless it pops up and decides not to leave then it would be a good idea to have it on a diagnostic meter

Could just be a DPF sensor blip, making the car think it had a fault for a second. Keep an eye on it and if it does it again pop it in to dealer to have any fault codes read.
