it means the 02 sensors are dead. (them or worse) 62 seems way way too high , the service manual tell you spec on this keyon,, idle and WOT, pressure spec, only that matters as does injector leakdown tests and injector balance tests. learn this the O2 sensors can only do a fine tune on fuel. if there are exhaust leaks, o2 lie if there are stuck head valves 02 lie (each slug of air does that) gross misfiring, P017x codes trim error.s that means the PCM can not do trim at all. the engine hot is not in closed loop as it must be. for this above reasons. no vin told no country told no full engine spec name told at all no service manual to read for sure injection and pressure test. and FPR tests for proper regulation at all engine loads. cant be done blind, zero books./ 5 engine there are for 325i no 325XI, 2.5L engine gas. the new FPR page shows 51PSI not not 62 FPR has 4 nippples n it, 2 for fuel and 1 vacuum it seems if I am right on this FPR, there are 3 pressures to test, keyon, idle and WOT vacuum in the plenum does that and is engine load. at key on and wot psi is highes and idle lowest. and is in the manual and my one line BMW pages stinks to high heaven. zero FPRR chapters there, sadly here is fprif vac hose 4 falls off PSI is max. due to vac MIN>port 1,2,3 , one is pump input, one is to rails and one is return to tank line my best guess. which one is which IDK. rail pressure is what matters,key on pressure is highest and idle is lowest.if not fuel trim fails hard. no 02 can cure insane high fuel pressure. the PSI drop is about 5psi.sorry i do not have the real service manuals5 psi less than atmospheric pressure (keyon) also called "constant differential pressure" on the injector and FPR does that magic. on newer cars have FPR sensor and can correct pump or FPR errors. but not yours.
