Restricted performance

This morning on way to Birmingham after about 150 miles I got the red warning triangle and restricted performance message, a bit further on the yellow triangle came on as well as the red one.

having read the fault codes I had
P006A manifold absolute pressure mass or volume air flow correlation (pending)

P0528 fan speed control circuit no signal

P2456 diesel particulate filter differential pressure sensor circuit intermittent/erratic

does anybody have any pointers as to what is wrong. I have cleared the fault codes and will take it for a spin later today to see what happens. don't fancy being stuck 179 miles from home

at the moment RAC reckon it is a split in a pipe, possibly air inlet manifold so it is getting recovered home.

then I have to find a way to get myself home on Friday Smile
