Hi Stacy Welcome to the Forum Are you aware of www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model. The small exploded drawings are quite helpful for seeing where stuff fits. The part numbers will help with parts .if needed double click the part number and it should bring up a list of alternates and other models they were used on Hope this helps Dave

Morning Paul Electrics and fluids never mix well, probably easier to change the controller get the part number of the unit fitted and Google for sources Good Luck Dave

Morning Philip Welcome to the Forum The spark plugs are fitted with their own compression seals so make sure they are (a) correct for your model (b) fitted and tightened correctly (c) Check the coil packs your misfire could be a failing coil pack (change all 4) What oil leaks do you have? Also at 92k the supercharger service is looming? Dave

Morning Bill Welcome to the Forum When was the coolant level checked? The fact that the hose is Collapsed when cold suggests to me that the system may need bleeding I take it the car doesn't overheat (temp gauge in the middle) has the Thermostat been serviced/changed? Dave

Morning Norm Welcome to the Forum Sounds Turbo related to me, turbo's lead a hard life and my personal feelings are extended service times don't help. Hope they get it sorted for you Dave

Morning Steve If your car is Xdrive I am amazed you haven't had transfer case issues? Check www.realoem.com for correct sizes whether yo choose runflat or not incorrect or mismatched tyres are the fastest way to damage the transfer case Dave

Morning Paul If changing the seals make absolutely sure all old material is removed or there will be leaks. I take it you have looked at www.realoem.com for any help Dave

Morning William Welcome to the Forum I can't offer much help other than this the rear light cluster will need a new gasket set if removed I believe the rear cluster is LED so a search for "How to's" on repair may yield something. Good Hunting Dave

Morning Joshua Welcome to the Forum Tasty car ENJOY Dave

So what was plugged in that wasn't there when testing? Phone charger? Rear entertainment system? Where did you monitor the current drain? At the battery or at the charging point under the bonnet? You have changed the battery is it correct for the car and was it registered to the car to ensure correct charging. Important point only ever charge at the charging points under the bonnet never direct at the battery or damage can be caused to the cars onboard systems. Dave

Talk to the seller (hopefully a Garage) and get them to fix it, it could be simply a low battery that needs a good run or charging. Or it may be something that needs more investigation. Dave

As the engine is not running in E mode it makes sense that if electric pump is not running the coolant won't circulate that is where I would start Dave

If you go back to Realoem first look at the Engine section you will see where the Waterpump and Thermostat housing are mounted To get to them you do have to take off acoustic covers and other bits. If you look at the Radiator section you will find the Electric Water Pump. As your diagnostics are showing 0 movement have you checked associated fuses and relays? One of the main advantages of using a BMW diagnostic program such as ISTA is it come with BMW workshop information and diagrams. Realoem is a part of the diagnostic as well making sure if buying parts you get the right part number. Slow warm up is normally a sign of a thermostat failed in the fully open position (or even a missing one) Dave

Main fuse relay box under the bonnet

Morning Dave A number of things to check (1) is the car going to sleep? When shut down and locked the "P" symbol remains lit while systems shut down it can take 15mins or so for it to extinguish. If it doesn't then some system is keeping the car awake and drawing power. (2) Have any toys or accessories been added ? The alarm bonnet switch has been a favourite over the years (unplugging it often sees the drain stop) as has the audio system pulling fuses is often the only laborious way to find issues. Dave

Morning Steve Take a look at www.realoem.com you can search by model or Vin number the small exploded drawings are very helpful Dave

I take it both new key fobs are Genuine BMW? Footwell Control Module been checked? Dave

Morning Julian While diagnostic apps are a good guide they don't fix things on their own. Take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model. Then search the sections for information, each section will provide small exploded drawings showing where things fit. I have never had an F45 to fiddle with but from memory there is an Electric coolant pump is that running? The electric coolant pump works alongside the main engine driven water pump and thermostat if the thermostat is stuck or failed it will need changing if I was in there I would change the water pump as a precaution. Dave

Hi Rod Welcome to the Forum Never tried, you may find information with BMW UK Classic section, or talk to an Upholsterer My experience tells me they will say try it on an area that isnt obvious first ? Dave

Morning Dee Welcome to the Forum To be sure you need a scan with BMW capable diagnostics the codes you have are Generic so while a pointer are not specific Dave

As you changed the Battery have you been into settings on the car and reset stuff in there also check the main thermostat Dave

Hi Bill Welcome to the Forum First Google BMW Specialists there is a register so yo should find one nearby who will have all the experience to diagnose your car properly fingers crossed it may be something simpler Dave

Top man Happy New Year Dave

Hi Lynda Welcome to the Forum The symptoms you describe are classic transmission wind up. The cause is almost always mismatched tyres so check that tyres are (A) Correct sizes for your rims (B) If tyres are correct and in good condition then it could be that the Transfer case fluid needs changing If he changed the the transfer case motor BMW advise the Fluid be changed at the same time. Hope this helps Happy Christmas Dave

Hi Mark Welcome to the Forum ENJOY YOUR BEEMER Oh and there isnt much wrong with Jap cars my wife's car is a Subaru Outback with a full Perrin engine upgrade (just over 400 whp) most of our local boy racers have learned what it is over the years 🤣 Happy Christmas Dave
