Welcome to the Forum Enjoy

Car designers engineer them to be easy for the Production line to build not for us to work on Try disconnecting the Neg on the battery as said it is a Dealer trick to clear glitches ? Also check locally for a BMW Specialist they may well be less cost (hourly rate) than the Dealer but should have the correct Diagnostic Kit Dave

Morning Rod BMW used to tell owners "Gearbox is Sealed for Life" in fact what they mean is the normal 60k/3years Warranty responsibility ZF who make the boxes recommend service at 60 - 100k/km at 190k/km I would find a ZF specialist and get them to look at it. They can run a full diagnostic on the box and give you a better feel for whats going on. Get the gearbox mounts checked I have seen a failed mount which gave odd behaviour Dave

Get a second opinion on the turbo normally an oil seal gives Blue smoke not white plus it wouldn't clear Dave

Morning John Welcome to the Forum The simplest way would be to talk to your nearest BMW Dealer it wont be the cheapest but they should be able to help Dave

Then you might need someone with BMW ISTA to run a scan and reset If your car is 2020 it is still under Warranty so can't/won't your dealer help? Dave

Morning Gary Welcome to the Forum When the car battery went flat was it (a) replaced? (b) charged ? (c) jump started ? If it was Jump Started where the jump leads attached in the correct place at the under bonnet charge point if not damage can occur If it was charged it should have been at the same charge under the bonnet or Battery removed for charging If the Battery was replaced has it been registered correctly to the chassis It could be the fuse in the back of the radio You could try disconnecting the Neg lead for 15 + mins that is a Dealer trick to clear faults and reset stuff Hope some of this helps Dave

Morning Steve You should have 2 Diffs Front and Rear, the Transfer case is on the back end of the Gearbox and splits drive to the Front and Rear Both Diffs will use a Synthetic Hypoid 75-90 type oil check your handbook The Transfer case will use a Special DTF type Transfer Case fluid again check your handbook or www.realoem.com Dave

Try this 1. Without pressing the brake/clutch, press the start/stop button 2. Wait for the service reminder to disappear 3. Press and hold the odometer reset button. ... 4. At the value you want to reset, press and hold the odometer reset button. ... 5. Press and hold odometer reset button again until value is reset

When I have done this I always use the button in the bottom left below the speedo never needed to go into I Drive ? Have you checked You Tube ? Dave

Morning Dan Always try the low cost simple things first Once things are clean and operating correctly if you still have the smoke something is worn, split or broken. An engine at higher mileages could have worn Turbo seals or worn Valve stem seals it doesn't take much oil to give a cloud of Blue smoke. With the crank pulley is it worn or loose? I have seen 2 loose ones 1 caused a lot of damage when it threw its belts Dave

Morning Steve BMW tell people they are sealed for Life but for Life read end of their warranty responsibility ?? ZF who actually make your Gearbox advise Fluid and filter changes at 60 to 100k intervals, personal preference is I change the Diff oil and Transfer Case fluid at the same time My X5 4.6is has 164k on the clock and I have just serviced the Gearbox Diffs and Transfer case for the second time changes are smooth and I tow a horse trailer through the summer months. My E70 has just had its 1st transmission service in my ownership at 117k Dave

Morning Michael Try this, Turn the ignition to ON and press the odometer reset button located on your dash. Hold down the button. Your display will show a yellow triangle with an exclamation point inside. Then, it will enter the service menu. Use your turn signal stalk to find the brake light setting. Press and hold the BC button on your turn signal stalk to reset the light. Dave

This car is going to keep you out of the pub Dan Dave

Hi Dan Operating the Turbo actuator doesn't mean the Vanes are working what you describe is classic worn turbo seals Dave

Thanks for the update Julian Now enjoy your Beemer Dave

Top Man Great information on FRM repair/re-mapping service Dave

Morning Skevos P12BA is a Generic code which points towards the inlet manifold, so check carefully for any air leaks split hoses and gaskets. It could be the pressure sensor or MAF. A scan with a BMW capable diagnostic program would tell much more. Take a look at www.realoem.com put the last 7 digits of your Vin into the search box it should bring up your Model then search the engine section. There are small exploded drawings that will help identify parts and where they are. Dave

Morning Paul I have seen split Filter housing's on an E46 and E53 almost identical to your pictures, both cars had dripping heavy oil leaks. Neither had anything as catastrophic as you had. The guy with the E53 had managed to paint the engine bay with Castrol though where the fan had thrown it around. Good result on the save matey Dave

Welcome aboard Dave

Plus one for Dan Though the job can be done right it brings to mind the old saying "If you think professional is expensive wat until you have paid for amateur" Don't let them off the Hook Dave

Hi Paul Use the last 7 digits of your Vin to search www.realoem.com it will bring up your model the look in lights Before spending your hard earned are the lens's clean? Not clouded. A bit of elbow grease could be the answer Dave And yes the old saying is right

Perseverance pays well done Richard

Hi Dan White smoke is normally fuel or water vapour but I have seen one where a leaky brake master cylinder was was letting fluid into the servo worth a check Fuel Pressure checked? When was the fuel filter last changed (if ever)? Mass air Flow meter? Any chafing or pinch marks on the engine loom Thinking out loud Dave

Hi Dan Never heard of any one trying (I have used a Local Diesel specialist to refurb injectors) I guess you could try soaking them in something like Redex Injector Cleaner Dave
