Hi Guys

My current setup is;

03 S60 D5 with recon 185 injectors, Hybrid Turbo, DO88 intercooler, 2.75" downpipe and exhaust.

On the flat it runs great but if it's under load especially 4th / 5th or going up a hill, I get 'Engine service Urgent'.

The error codes relate to fuel rail pressure too high or too low.

I've replaced the fuel filter with a genuine unit and tested the in-tank pump (which is set to run constantly). I get a decent flow at the High Pressure pump.


I'm wondering if the standard 163 high pressure pump can't cope with the demand of the 185 injectors? Or maybe a dodgy regulator?

Has anyone swapped the 163 pump with a 185 pump (0445 010 111)? I know there different sensors etc but would the black part of the pump swap over?

Thanks
