If you have a multimeter remove and test the fuses for continuity (OHMS) as fuses can look OK but they have blown. If your replacing fuses ONLY replace the with one of the Same colour and Amp rating.

Question edited for clarity. changed your Poly Vinyl Chloride (PVC) into Positive Crankcase Ventilation (PCV), and added some punctuation to make real sentences. Your car is run by computers, the computers have diagnostics and will tell you what's wrong. You can't guess faults like you have. A Professional Grade Scan Tool computer can diagnose all the computers, modules, sensors and systems in about 40 minutes. It can even record what happens and what goes wrong as you are driving! https://www.google.com/search?q=mobile+auto+electrician+near+me ..

https://cararac.com/blog/bmw-no-crank-no-start-problems-and-solutions.html This will give you a few ideas of what to look for. Make sure you are getting battery voltage to the fuse box.

To turn off HDC on a BMW, all you have to do is press the HDC button located on the center console. The button will have an image of a vehicle going downhill with a speedometer above it, and you'll know it's off if there are no lights illuminated above it. If you ever want to turn the system on again, just press the button again.

Since you fixed the fault by scan advice and was ok and on testdrive another limp mode came up, just check again with your scan to see what is the possible cause for it. Probably the crank sensor.

6 years different and a different series? If only life was that easy! Some BMW have a mechanical pump driven by the serpentine belt, and some have an totally electric powered pump. Just buy one for the model you have. https://www.google.com/search?q=2012+BMW+535i+water+pump or https://www.google.com/search?q=2006+BMW+330i+water+pump Rock Auto are a good suppliers, have images and different makers and 'qualities'. https://www.rockauto.com/en/catalog/bmw,2006,330i,3.0l+l6,1431850,cooling+system,water+pump,2208 ..

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?

linkage bad or PRNDL switch failure. the service manual covers this, get i?

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.
