Check the basics first. Is battery fully charged? This is the most common reason for a no crank, no start. What exactly does it do when you turn the key? Nothing at all, no lights, no 'click' as you turn the key. A slow lazy crank?
no year car told at all.
using voltmeter
what is battery voltage at idle.?
not told' 13. to 15vdc is par, if below the alternator is dead or its fuses blown.
if ALT is dead, driving the car , far (30min) will make engine stall and be dead,until battery is jump started or charged.
that lamp comes of a reason, it means
fully load test the battery and test the alternator correctly
check all fuses
scan the OBd2 port with a scan tool for charge system errors.
If the battery is bad,the alternator can in fact refuse to charge it.
intermittent battery cell shorts or opens can do that.
batteries over 7 years are , love to fail.
"it turned on after oil leaked flashy/, "
i am not sure what flashy means.
DId the PS pump fail and leak and squirt PS fluid to some electronics
under the hood, that can be vary bad, if did.
be more clear on PS leaks, leaked to where. ? matters
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./
Hi I have been told that the first thing to do is to check thr power steering fluid level, if not that then you should check that battery voltage is ok and alternator is working ok, hope this was some help all the best.
all cars made for 100 year like to short
cheap harnesses. that rub, fray and short from VIBRATION not more it does the worst it gets.
my buddy captain Dick almost died in C5 Galaxy with short;in the harness mid cargo bay.
he saved the day by pulling the connector there and the fire ended. ( got burn hands doing so but lived)
on your car pull the loads to HVAC controller
may be the blower motor shorted.
test and isolate related parts and the actual shorted device is found, and fuse holds
or is wrong fuse there. oops use correct amps rating only.
2009 is the year of BAD CAPS PLAGUE. so the controller caps may be hard dead shorted out
as they surely love to do. then. (cloned caps H3LL)
The codes you provided suggest that there may be a problem with the throttle position sensor or the secondary air injection system in your BMW 325i. However, it's important to note that these codes alone may not be enough to diagnose the exact issue.
Here are a few possible causes and troubleshooting steps you can take:
Check the throttle position sensor (TPS) - The TPS is responsible for communicating the position of the throttle to the engine control module (ECM). If the TPS is faulty, it may cause the engine to not start. You can use a multimeter to check the resistance of the TPS and compare it to the manufacturer's specifications. If the TPS is out of range, it may need to be replaced.
Check the secondary air injection system - The secondary air injection system injects air into the exhaust to help reduce emissions. If there is a problem with this system, it can cause the engine to not start. Check the air pump, air pump relay, and check valve to make sure they are functioning correctly.
Check for loose or damaged connections - A loose or damaged connection can cause electrical problems that may prevent the engine from starting. Check the battery connections, ground connections, and all wiring harnesses to make sure they are secure and free from damage.
Check the fuel system - If the fuel system is not functioning correctly, it can cause the engine to not start. Check the fuel pump, fuel filter, and fuel pressure regulator to make sure they are working correctly.
If you're not comfortable performing these steps yourself, you may want to consider taking your BMW to a certified mechanic for diagnosis and repair. They will be able to use diagnostic tools to pinpoint the exact cause of the problem and make the necessary repairs.
the cooling system needs service .
get some?
do you want 25 guesses?
or all tests to find it.? and tools and how to use those tools.
never run sans STAT it can cause big turbulent problems at the pump impeller. (an new one is what we do, for sure 10 years old is its engineered life span so is DUE.

1,2,3
new cap , new STAT
step 3 is find leaks/ on ground or on passengers toes?<heater core.
and lots more sorry not typing them again and did so way too many times here.
the hot coolant is under 15psi, and if there are any leaks
this magical fact (physics) allow you to find leaks easy, .
parked hood up. leaks. find them. even take your time and look hard.
