It appears to be a common failure of the Aisin gearbox. You may consider servicing the gearbox; however, I remain sceptical about a permanent resolution.

Faulty bulb or grounding issue. Exchange the bulbs laterally to evaluate that component.

Firstly, I greatly appreciate your response! This situation is overwhelming me! I verified the electricity from the fuse through the firewall connector. From that point to the trans connection plug, power was sent to the GCS. I was attempting to ascertain which pin directed to the subsequent location and what that entailed. I am presently attempting to identify the CAS module to confirm the power and signal to it at this moment.

My X5 intermittently displayed "transmission malfunction" on the dashboard for approximately four months. No drivability concerns were present. Suddenly, it failed to crank, start, or activate the accessory lights upon pressing the start button. I scanned it and discovered a trans code indicating a voltage of less than 6.7v. I examined the battery and measured 12.43 volts. I charged the battery nonetheless. I subsequently verified the power flow from the battery to the fuse box and then to the transmission connector. I replaced the starter as planned, and I also replaced the GCS/valve body under the assumption that the transmission computer was defective. Unsuccessful. What should I do next?

Indeed, you have initiated progress! As I mentioned, acquiring quality wiring diagrams is essential, although they are more difficult to obtain in the present day. The subsequent steps will involve verifying continuity and voltages, which is somewhat time-consuming. It is advisable to inspect the passenger side in the same manner as the driver's side, as the CAN bus also operates on that side. If it fails, it will affect the entire system. I shall continue to contemplate.

Hello, I have encountered similar issues previously. I must assert that the switch packs on E90 models are often quite reliable, therefore I personally doubt that this is the reason. CAN bus systems are quite problematic, as they are dispersed throughout the vehicle and are easily disrupted by moisture. Begin by disconnecting the harness from the driver's door; there is an 8mm bolt on the vehicle's body side, after which you may detach and unplug the multi-plug. Inspect for moisture, visible corrosion, etc. If it is a connectivity issue, a thorough cleaning and manipulation may suffice. If acceptable, I will likely examine the harness behind the door panel. To proceed correctly, a wiring diagram is essential; nonetheless, these prevalent concerns may suffice! Best of luck

Greetings to all, I possess a 2001 BMW 530d, which I imported from the UK to Zambia in 2012/2013, and it has significantly influenced my automotive experience. I have consistently found pleasure in mechanical work on automobiles, and recently I have developed a profound interest in diagnostics and ECU systems, which has led me to this point. I anticipate acquiring knowledge, exchanging experiences, and engaging with the community. Thank you once more for hosting me!

Perhaps a minor fissure in the catalytic converter or manifold?

Greetings, everyone. Thank you for the responses. I received one email back indicating that my model is Enavevo. To upgrade to ID6, including VIN matching and coding, the cost will be £1,095.

Thanks for the advise guys - I have searched, and the only model numbers I can locate are in the attached photograph. Looking around it says that an obsolete software version, presumably belongs to NBT EVO system?? A new display will presumably require programming, correct? Should I also update the obsolete software, in your opinion? It is uncertain whether it is relevant, but the radio does not include a CD/DVD player.

I have Bluetooth connection which works ok, only dont have the sat nav and dab, which I would like to upgrade but unsure as to which Idrive I have currently.. I have verified the VIN on several websites, which indicate that the DAB and satellite navigation are standard features; however, I find myself perplexed and suspect that the dealership may have misled me. The dealership stated that the vehicle did not possess satellite navigation and was in poor condition upon receipt as a trade-in.

Greetings, I am seeking guidance on upgrading the navigation and DAB system in my 2019 BMW 520 G31, which now lacks these features. Any assistance would be appreciated. Currently looking at ebay, do I need a new display screen and radio unit? Would it be more advantageous to acquire a new Android display unit radio? For your information, my current display unit lacks touchscreen functionality, and the radio does not include a CD player; I am uncertain if this is relevant. Thanks for the help!

I understand your perspective and your justified caution. My perspective is that a car valued at over £60,000 is unlikely to be test-driven by seventeen-year-olds, though I may be mistaken. According to TDudette, the running nowadays is not really necessary. Only a genuine M automobile need a break-in time, as the other models have not undergone the modifications by the M division.

The few instances in which I have observed the N47 producing that error, despite an adequate oil level, occur when the oil has not been changed for an extended period, resulting in sludge accumulation. I do not wish to be pessimistic, but it often did not take long until the bearings failed.

Run-flat tires will adversely affect whatever vehicle they are installed on.

Additionally, which vehicle and engine?

The issue with selling to any trader or dealer is that they will prioritise condition, mileage, and service history above any modifications made, thereby offering a trade price based only on those factors.

I have just seen an email from bimmerforums today. Regrettably, I spent excessive funds without achieving accomplishment, leading to my decision to desist. Thank you

Thank you for your response, PixelMaster. Apologies for the oversight; the fuel filter has been replaced in conjunction with the air filter for the standard air box. Additionally, I neglected to note that the charge pipes have been inspected and are functioning well, with no splits present. The low-pressure pump has been inspected and is functioning properly.

Greetings everyone, I sincerely apologise if I am violating any regulations. This is my first experience on any forum, so I appreciate your patience. Initially, these are my specifications: BMW F20 116D 2.0 Diesel Decat / DPF Removal (Downpipe; the original DPF is still available) EGR Deletion (Software and Blocked) Stage 1 Tuning Short Ram Air Intake Enhanced Intercooler I am seeking advice or insights about my BMW. I am repeatedly seeing the problem code: 247500 Rail Pressure Plausibility, Quantity-Controlled. Positive Control Deviation: Insufficient Rail Pressure. This issue arose during an enthusiastic drive when I passed another vehicle and thereafter had a complete loss of power. Notably, no drive-train issues were shown, and the vehicle entered a limp mode. This incident occurred around three months ago. At that juncture, my BMW emitted black smoke from the exhaust at wide open throttle, and upon reaching elevated speeds, a drivetrain fault would occur, resulting in limp mode activation. This is perplexing, as black smoke typically signifies over-fueling, yet ISTA codes indicate insufficient fuel supply. I already examined the forums and discovered that another user had a same problem, which was attributed to a defective remap. In my situation, all modifications and enhancements were finalised over a year ago with few complications. Regardless, after perusing that thread, I resolved to revert my vehicle to its original configuration, reinstating the DPF and EGR, removing the remap, and reintroducing the original airbox and intercooler; however, I had no success. I consulted a local mechanic who originally diagnosed the issue as the MAF sensor, which we changed without success. He conducted testing and saw that the High-Pressure Fuel Pump (HPFP) exhibited decreased pressure. Subsequently, I reluctantly replaced it with a new unit; nonetheless, the issue continued. He considered that the problems may stem from the fuel rail and injectors; so, I replaced the common rail and all the injectors. The common rail was new, but as expenses accumulated, I chose to get reconditioned and tested injectors. Once again, the same issue. We then considered the possibility of a failed turbocharger, so he removed it; nevertheless, the turbocharger was in good condition. I am now at an impasse, both financially and emotionally; I have an affection for this automobile, however I am experiencing the sunk cost fallacy. I am open to any suggestions you nice people may provide; else, I will regrettably have to relinquish it. I apologise if I have violated any regulations and would really appreciate any assistance.

I checked for any codes on INPA, but found none.

Indeed, it was. Exploring several options seems to be a viable endeavor; it is certainly worth doing.

I am certainly inclined to do this task and possess the capability to do so; but, I now lack the necessary resources, namely the ability to elevate the automobile and position it below. I donned a new headgear after the service. This model has an electrical system instead of a dipstick. One possibility is that BMW performed an engine decontamination procedure, which involves flushing the engine by connecting a pressurized machine and a filter. They advised proceeding with it...
