Hi Ian Welcome to the Forum Try www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model then search for what you need, this is a BMW online parts list as used by BMW Dealers so it should have what you need. Try the Audio section but also check the trim and body sections BMW don't always put stuff where you think is logical. If you double click the part number it will call up any alternates Hope this helps Dave

Morning Mark Welcome to the Forum Just look for the Tyre Pressure plate it has all the information you need you should find it on the Drivers door pillar. Looks like this Dave

Forgot to say Android up grade is the way to go got an Erisin Android screen in my X5 E70 Dave

Morning Will Welcome to the Forum A very nice looking motor, the brakes though !! That rotor looks like its been parked under water the inner half of the rotor looks thinner (if it isn't an illusion) possibly the calliper is or has been binding. I would check all the suspension bushes front and rear as my experience is their life is 80 to 100k. I am half way through a suspension rebuild on my X5 3.0d at the moment Brakes I changed last year. My brother inlaw has always run 5 touring's as his business car, on his 6th now (2nd 540d) he has all his cars stage 1 mapped from new all his cars have been run to 150k+ without any dramas. So I say work through the niggles and ENJOY Dave

Hi Paul If your checking filters when was the fuel filter last changed remeber an engine needs Fuel Air and Spark so if the spark is there ? Dave

Whoop Whoop Great result Nathan

Morning David Welcome to the Forum BMW Dealers or the normal on line auction sites would be my starting point. As always look at several make sure they have the accessories you want and everything works as it should. Then History History History Good Luck with the search Dave

Morning Antony Welcome to the Forum Th A pillar will have airbag and wiring behind it I would think or even one of its own holding clips not fitting correctly. Check www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model. Then check the body and trim section so you can see what is in there and how it fits Good luck finding it Dave

Morning John Welcome to the Forum Are you sure it is the Module I changed the sensors on both my X5's with sets from Amazon all worked straight from the get go. The faff was Wheels Off Tyres Off to fit them. If your certain it's the Module check www.realoem.com, put the last 7 digits of your Vin into the search box it will bring up your model then find the item you need. When you have found your item double click the part number and it will show a list of alternate numbers that can be used and models they were used in. Then search the Net using the part number/numbers for what you want. Check the specialist dismantlers also. Good Luck Dave

OK so when you upgraded to Xenon did you use OEM parts or Aftermarket? If the parts are OEM are they correctly coded to the car? If not that is probably where the issue could be, the other culprit is in the wiring I know from helping several people who upgraded 5 series to LCI lights that often the correct connectors are needed and poor modification of the lighting loom was often a nightmare to correct. With your conversion you probably need a wiring modification to the Earth plus an inline resistor to stop flicker. I have also read that the Light switch may need changing, in earlier cars the FCM may need changing and re-programming. If you are OK with DIY on your car and know how to use a Multi Meter you should be able to sort it. You will need either a laptop with INPA/ISTA diagnostic software on it or the help of someone who has if any coding/programming is needed. Dave

If a connector is not fully home or has a poor connection vibration can cause intermittent contact. A lamp (the Bulb) can suffer the same sometimes a lengthy period before total failure Did the technician suggest a cure ? Was the technician a BMW one ? If you turn on the ignition don't start the engine and turn on the lights what happens with out vibration.

The fact the MAF was changed doesn't mean it's working (Been there) so I would double check, 1 is it the correct part for the car and 2 that it works. Throttle body I believe were pretty unchanged from 99 through to 2005/6 they were also used on many other models so check realoem Good Luck Dave

Morning Randy Welcome to the Forum Depending on the model/year the type of transfer case changed and they don't use the same Fluid You can check www.realoem.com (if you aren't aware) just put the last 7 digits of your Vin into the search box it will bring up your model. Early transfer cases the chain can stretch at high mileages or where incorrect tyres are or have been fitted which could be the cause of your vibration. I have rebuilt 2 Transfer cases (both on X5's both victims of incorrect tyres) there are parts available from several sources the job is straight forward but needs the case on the bench. Also worth checking the transmission mounts if they are starting to fail that is another cause. Hope this helps Dave

Morning Nathan From the 1st video it seems the right hand outer lamp is flickers but the left (drivers side) is out 2nd video left lamp is on but after restart not Have the Lamps (bulbs) been changed/checked? It looks as though that is where the issue is I would check all connections make sure all connectors are fully home same with the Lamp (bulb) connectors Dave

Morning Dave Welcome to the Forum The fact that codes are self clearing would indicate they are symptoms not the cause. Check the Mass Airflow Sensor and the Throttle Body I have experienced faulty units with both that didn't throw codes. Your restricted performance would make me think first throttle body or throttle pedal position sender as a starting point. When you scan are all control units seen or are some not responding? (Greyed out) Good Luck Dave

Morning Nathan Welcome to the Forum A little confusing above you say you replaced the right light and the right light is flickering but not the one you replaced?? A quick look at Realoem tells me the part number was for the Left hand lamp. Is it the DRL (eagle Eyes) flickering or the Xenon Headlamps. Flickering could be a failing lamp (Bulb) or an issue with the Control unit First check all the connections pay attention to the Earth points both sides the Xenon control units are high voltage so if you don't know what your doing get either a BMW Specialist or Auto Electrician to help. A Diagnostic scan may help as well. Hope this helps Dave

Morning Welcome to the Forum I take it your US based but the same rules apply where ever you live in the world when buying a used car. A car can have several owners and if just one doesn't care there could be a legacy of wear and tear that isn't obvious at first. So History, History, History and then History. With around a 100k on either car if properly maintained they should both be reliable however Suspension Bushes Shocks Brake Discs and Pads will be suspect unless they have been changed during the servicing. Gearbox normally the most abused part of a car as they are rarely included in service schedules so check that. That would apply to both cars What ever your choice ENJOY Dave

Morning Wayne Welcome to the Forum 1 When was it serviced last ? (not just an oil change) 2 How many miles on the clock ? Black smoke is over fuelling or unburnt fuel, you say the back of your car is covered in soot which would indicate there has been an issue for some time. The jerking could be related or it could be Tyres that are causing it. Your X3 is AWD if front and rear tyres are not matched then damage can be caused to the AWD system. Have you had tyres changed recently? If you are not able or capable of doing the work your self you need a Good Garage or preferably a BMW Specialist to help diagnose and fix it. Dave

You hit the nail on the head it is addictive 😈 I have a neighbour who has a Tesla incredibly quick when its in "Insane" mode but absolutely no soul

Now that sounds like a plan 😁 you should be able to get a solid 400+ whp without waking the neighbours up (much) 😇 Go for it would be my thoughts My X5 4.6is has Dinan Throttle Body Dinan Cams (all 4) and a remap 407 whp after a Rolling road session. The X5 3.0d has a bigger intercooler and remap and has 355 whp but with the diesel its the increase in torque that is the biggest plus. My wife's Subaru Outback has a full Perrin engine upgrade with well over 400 whp 🤣😂 Dave

Morning David Sorry never seen them on a 135i so cant comment I have fitted 100 cell cats to a 4.4i X5 for someone as the old cats were blocked and causing issues. He chose them as they were a far cheaper option than OEM or even aftermarket items from an Exhaust centre, the car runs great and passes it's MOT OK I also had 100 cell cats on 3 of my Volvo T5's but with a stage 3 remap and 3" downpipe (gave 360bhp at the wheels on a rolling road) The tuner advised they were not needed until Stage 3. Dave

Morning Brian Where did the refurbed unit come from are you sure it's OK If the unit is OK are the fuses OK check them all even the one under the Quad lock connector on the radio it's self. If the BM54 and all it's fuses are OK it could be a fault with the FCM (Footwell Control Module) BMW and several specialists will tell you the only answer is a "New FCM" Not so a used FCM can be used but you will see a tamper dot by the mileage as the Mileage stored in the cars IKE and the new FCM wont match. Everything will work though. If you invest in a copy of BMW 1.4.0 (about £30) or know someone with a copy the FCM can be reprogrammed (Many Specialists and BMW will tell you it can't be done) It takes longer to swap the units than it does to reprogram plus if you have your own copy you can run diagnostics whenever you wish and program functions in the car. Good Luck Dave

Great result Andrew What fault did BMW find/fix Dave

Hi Chris If you aren't aware look at www.realoem.com (BMW Parts List) put the last 7 digits of your Vin in to the search box it will call up your model. Then search the brake section if you double click the part number it should show any alternative Part Numbers and Models they were used in An alternative I have used on a 325i that had a handbrake not holding because the teeth on the quadrant had worn was 15mins with the welder and a file to build up and reshape the worn teeth. 3 years later it is still working fine (our Sons friend) Stu is right about Quarry Motors but if they can't help try Googling BMW Specialist Dismantlers there are about half a dozen from memory worth an email or two Dave

Morning Welcome to the Forum If the Z4 is a drop top you have the weather for it 😅 Dave
