Engine management light stayed on, reset by dealer now OK.
Rear N/S tyre very noisy; found problems with inside tread lifting. Awaiting comment from Dunlop.
Excellent performance.
Fuel consumption getting better; now averaging 45-50 mpg.
With reference to your tires, get the suspension geometry checked, as there have been a few recalls on this, causing the tire treads the wear in an unusual manner on the rear. The dealer should really do this, they may tell you it doesn't affect the vRS, and you might be able to get the tires replaced for free.
