Very possible but start looking for a vacum leak 1st and check long and short term fuel trims |

can the sport breaks system be bleed like a normal car or will it have to be done by diagnostic like the p38 ? |

I think it depends on how much of the system you have disturbed, if just replacing fluid or fitting new flexi brake pipes etc. can be done the old method with a jar and tube, pressure bleeder or vacuum pump etc. If the hydraulic control unit etc. has been removed, replaced for example I believe it has to be bleed via diag. equipment to I assume open various valves/solenoids. I am in the near future about to change the fluid and renew the flex pipes on mine so did read up on it a bit. As a point of interest when I replaced the accumulator and steel brake pipes on my old P38 certainly never connected it to any diag. tool to bleed the system.
