Hi,

On my 2007 RR Sport SC, DR light turns on Red as soon as I go around a corner. Indy shop read the codes (C1119-09, C1119-62, C1B11-62) and found very little to none fluid contamination in the reservoir. The filter in the valve block was crushed and had to be replaced. They suggested I replace the valve block, as the system shuts down right away and doesn't allow further testing.

Now 2 codes C1119-09, C1119-62 are related to hydraulic pressure and C1B11-62 is pressure control valve. Does it mean pressure is not building up because of bad pressure control valve, a stuck valve inside valve block or is the DR pump not building up the pressure.

I want to understand the error codes to figure out what could be wrong with the system, instead of start randomly replacing expensive components.

I would great appreciate suggestions, if I should replace the valve block or the DR pump?

Thanks
