Well 500 odd miles seems to be the accepted norm for regen intervals. But 60+ miles/1h 40 mins sounds an awful long time for it to complete. Actually your "usual" of 30 miles/40 mins seems quite long.
Has it had any (many)aborted/partial regens (since the last one)meaning the DPF was more "bunged up" than might normally be expected ?
