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.
