You need a diagnostic session with someone who has BMW ISTA/INPA There are pressure sensors on the DPF on the Fuel Rail on the Inlet manifold if one or more has failed it could cause your issue. I would start by getting a diagnostic done and checking the engine sensors Dave

Morning Julian Not a Bimmerlink user as I have my own diagnostic program but some thoughts are How is the car running? Do you have any Dash or I drive warnings? On start up you have a massive quantity of Control units all trying to talk to each other you only need one to timeout and it can give a list like yours. Remember it takes your car around 15/20mins to close down completely after engine stop key out car locked. Small variations in voltage are often mis read and show as faults so (1) Is the battery in Tip Top condition? (2) If the battery is good you should read around12.8 +v at the charge points under the bonnet engine off ignition on, around 14+ v engine running As your car is 2016 is it still on the original Battery? Dave

Morning Paul I cleaned and polished the Lens's and renewed my HID lamps with Osram Night Breakers and Main beams for LED H4 Works well for me Dave

Morning A diagnostic scan needed to be sure, have all the injectors been tested wiring loom checked Dave

Not heard this one before what mileage has the car covered? I would have expected some other symptoms if the DPF was restricted. Can't discount it though as recovery drivers tend to see more issues than us Dave

Morning Not just you all models with them turn off on car shut down and key out Dave

I know what you mean, when I upgraded the Front Callipers on my X5 4.6is to Brembo the service manager looked down his nose and asked me if I realised my front callipers were "non standard" and incorrect so could be unsafe?? I asked him why BMW used Brembo on their competition cars ? He gave a condescending smile and walked away, that was 2004/5 he still doesn't talk to me leaves me to his colleagues. Find a good BMW Specialist there is a Register so you should find one near you Dave

Welcome again Dave

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
