With the imminent arrival of my V40 I think my V50 has got the hump. It went into limp mode on the way home from work yesterday and is now at the dealers ready to be looked at on Monday. In the meantime I have a poverty spec focus for the weekend.
Check with your dealer again on delivery times. There's a new company doing all the transport and, as at 1st March, they aren't tied into the Volvo systems fully yet. Mine was booked for 18th March delivery and suddenly appeared on the 1st March without the dealership knowing. Worth a call
