Morning Michael Not good news and that has been going on for some time I would say so the seller wasn't truthful Check the Transmission for any sign of leaks especially around the Mechatronic Plug it may be worth carrying out a Service (Change fluid and Filters) see if that cures that issue. Your car was built in a time when BMW were saying Transmission was sealed for life !!! What they meant was sealed for the length of their Warranty responsibility (60k miles) ZF who manufacture your gearbox recommend service between 60k and 100k km dependent on use and climate Unfortunately if a service doesn't do it then the box will need a rebuild or changing, that wont be cheap either way I would expect a Specialist to charge around £2k + may be as much as £3k to fix it Good Luck Dave

Thank you, Dave.

Dave Thank you so much for your advice, I have checked the voltages with my ancient, analogue, meter and they appear to be in line with your numbers. I’ll get my son-in-law to bring his digital one round but it’s comforting to know that at the moment the battery is ok. Reckon I’ll still be ordering the charger though. Thank you again. Stuart

Wow, where was the bulge? I've never experienced those issues with a bulge on the tyre and had them on the inside and outside.

Thank you, and the same to you. Yes, the battery is under the bonnet and well hidden (why?!) so I must assume it is an AGM as I cannot access it to see. I can use the + and - to charge as the 12v is not constantly live unfortunately. I just wondered if anyone had a similar situation but think I will proceed with my first thoughts and invest in the appropriate Ctek.

Hi Nichola Welcome to the Forum and Happy New Year As far as I recall there are two parts a narrow tray and the lifting section. Just a thought does your car have rear seat adjusters if they have been moved that could be your problem Hope that is the fix Dave

Hi Dave, happy new year to you also, thank you for information, I’m sure it will be sorted

When it cuts out like that, especially quickly, it's a terrible feeling. Well done for persevering and ultimately figuring out the cause. Hopefully, the new injectors will resolve the issue so you may resume enjoying the X5 stress-free.

Morning Andy Seasons Greetings and Welcome to the Forum A bit more information if you can, what are the symptoms exactly ? You have had a lot of work done and parts changed has the EMF control Module been checked/changed ? Has the EMF actuator been checked/changed ? I assume all suspension parts and wheel bearings have bee checked ? Tyres are they all the same make and wear rate ? Sorry about more questions than answers Happy New Year Dave

BMW M Sport Coupe - Satin Black 78,000 miles Cream leather interior in great condition, no rips or tears. Drives beautifully - smooth handling, quick acceleration, and excellent on fuel. Recently had a full MOT and service (June 2025) and runs perfectly with no mechanical issues. M Sport Package - Heated Full Leather Seats - Cruise Control - Steering Controls - Automatic with Paddle shifters - Low mileage for its age Swansea, UK

Excellent explanation. A lot of the anxiety about DPF and EGR concerns is greatly reduced by real-world instances such as yours. Frequent maintenance and safe driving practices have a significant impact. I appreciate you sharing your story.

Morning Peter Most tyre places will write off the tyre if Goo has been used even if the puncture is in a repairable place and your quite right they hate the cleaning it needs That was one reason for me moving to the plug system simple to use and a permanent repair As said used it more on friends neighbours and family's only once on my current E70 X5 Good luck with the car ENJOY your Beemer Dave

Morning Ali Welcome and Seasons Greetings It could be a sticky or failing Hydraulic cam follower or a sticky Vanos solenoid. Clearly difficult to diagnose without being around the car If you use Cruise Control and feel a lurch when turning it off/disengaging it I would suspect the Vanos solenoids Dave

Well spoken, Dave. I've observed the same thing with prolonged service intervals: if minor seepages are ignored for a longer period of time, they grow into larger issues. Without the main dealer price tag, a competent independent BMW specialist can typically determine if the problem is actually a turbo or merely a seal.

I agree. I've also used a square configuration in the winter and found it to be very effective, particularly in the snow. In addition to making life easier, going a little narrower with the appropriate offsets typically results in cost savings.

Morning Christopher Welcome to the Forum and Seasons Greetings Not sure where you are but if your in the UK you could talk to ECU Testing or Cartronix to see if they could help. I take it you have searched for a second user Speedo or Binnacle ? That gives 2 possibilities strip it to get the part you want or swap the lot, you may need a Diagnostic like BMW 1.4.0 to register a changed unit and correct mileages Dave

Morning Welcome to the Forum and Seasons Greetings I would guess that if your seeing 10v at the signal wire then either (a) the sensor is toast (b) there is a short in the wiring loom to test at the DME you will either need to trace the signal wire back or get your hands on a Pin Out for the DME. I have seen corroded pins at the DME but that normally shows as no signal I assume you have checked the Crank sensor ? What Diagnostic system are you using Dave

Morning Firat My thoughts are that the trans codes are communication errors triggered by low voltage and or Can Bus issues. How is the transmission running ? Is it sticking in gears ? Are changes jerky ? Any other trans issues leaks etc when was it serviced ? My actions would be to start with a Fully Charged Battery, clear down the codes check the battery voltage was still at full charge 12.5v minimum Then put a clamp ammeter on the main starter feed and start the car measure the amps drawn stop the engine and check battery voltage. As I have BMW ISTA/INPA (I also have iCarsoft BMW V2) I would then run a diagnostic and record all faults I suspect the Trans Faults are not all that are there. Remember a Fault Code very often is a symptom not the cause Good Luck Dave

Hi 90 k is not a lot of miles when was it last serviced ? Are there any leaks anywhere? So the vapour does it smell ? Sweet smell (could be anti freeze/coolant) has it needed topping up? Oil smell is obvious Next check and test and change if required the Oil Temp sensor I believe it's on the Filter body on your model. See if that stabilises the Gauge Dave

Morning Nathan Welcome to the Forum and Seasons Greetings Sounds like a stuck lifter Dave

Hello mate thanks for the reply and sorry for lack of information. I think the engine is a n13 I had the car serviced in may and when I pick the car up and looked at the invoice they hadn’t change the fuel filter when I questioned the garage they said the fuel filter is part of the fuel pump so I said don’t it have a in line filter and they said no Thank you

Thanks for the reply. I've replaced the battery several times with new ones ( I should have mentioned that in the post) and unfortunately I lost the other fob. I've been procrastinating replacing it due to the cost. So I guess the next step is the scan tool. I'll let you know what I find out. Thanks.

Depending on engine, it could be a failing glow plug? Or maf leak? A misfire will cause a random jump and affect fuel consumption. Do you notice any fuel smell when the juddering happens?

Morning Mike Fuse box should be near side of the engine bay against the bulkhead so easy to get at with a couple of main loom penetrations into the Cabin. Never liked hacking into cables with splices etc 😁 Dave
