Don't know about comparitive prices.
The warning does suggest that the particle filter is partially
blocked. This will affect the performance and efficiency of the
engine. However it is an expensive thing to get changed, you won't see
any change out of £300, assuming the dealer fits a recon unit. If he
fits a new one, double that.
The message CAN also come from a faulty pressure sensor on the
exhaust, there are two, before and after the filter.
I took my filter off, and reverse flushed it with several kettle-fulls
of boiling water, wa****ng out a fair amount of white ash.
Haven't had the message since in 4k miles.

I will get the garage to confirm it is not a faulty sensor before they 
change the filter. I was told this filter usually gets changed around 45k

mine's done 57 now. Thanks
