Where is a 2003 bmw x5 e53 3.0L starter relay location, under the hood on top of the fuse box in glove box??
get the service manual.
the users guide does not cover relays.
or 2 persons find it.
one key start (cranking)
other one finds the relay that clicks cranked
bingo found, and can click even bad. (contractor burned inside) or starter is bad. ever hot wire a starter , keys in pocket?
or of all are dead , chances are the relay is good and
problem is up stream.(from relay)
PRNDL switch bad, in Park and Neutral both?
key switch failing (bet not)
IMMO lamp glowing wrong and engine is DISABLED.?
try both IMMO keys yet, it came new with 2 keys
battery is bad and dead
battery is only discharged
battery lugs, rusty and loose all 4ends good, 2 cables.
scan the PCM yet, see if it tells you what died?
no country told, and scanning is not the same outside USA.
it is based on secret country you. for sure. 2003
all ours 1996 up is OBD2, we invented it here. EPA.gov mandated. other countries lagged till 2003 or 07 or beyond.
not posting the country makes answers super hard and most times dead wrong.
your X5 has many Range rover parts. 99 up
best is check all fuses first
then scan it, never miss out on the chance it tells you
for example TRS (tran, range switch) errors (PRNDL)
be a shame to mis out on that.
or not cranking? is it? (is cranking dead? or just slow)
shift to Neutral and crank, to see if that works is really first.
covered this is , in the users guide, crank in park or N./
