Drivetrain malfunction alert

[Accomis]

Greetings, everyone, I received the aforementioned warning on my 2016 BMW 218d Active Tourer, automatic. Upon taking it to BMW for a diagnostic examination, they indicated a fault code related to the torque converter lock-up clutch, stating that a new gearbox is required, with a cost of £10,000.My vehicle is eight years old with 36,000 miles on the odometer; there must be other solutions available. Any recommendations? The vehicle operates normally, and the warning indicator disappears for many days after the engine is turned off.

Do you reside in proximity to a reputable independent BMW specialist? Considering the persistent EGR valve problems associated with that engine—Mrs. XWV own the same vehicle—I would certainly prioritise eliminating that issue before allocating funds to other repairs, since I presume the recall has not been addressed either. She has already replaced the EGR valve twice under warranty, and BMW has now extended the guarantee to around 15 years. On both occasions, the problem was preceded by drivetrain malfunction alerts.

Thank you for your response. The message was received, and shortly thereafter, I received a recall notice about the EGR. I drove the vehicle to the main BMW dealership, where they performed the EGR repair and conducted diagnostics on the drivetrain problem. It was then determined that a new gearbox is required. I am awaiting a response from an independent establishment but thought I would seek advice here as well.

If the gearbox is an Aisin, it is known for its poor performance, often exhibiting additional symptoms beyond drivetrain alerts, such as hard shifting and rev hunting. It is advisable to get a specialist's opinion, as previously mentioned. Conduct a search for "Aisin" here to find discussions related to that gearbox.

It is plausible that your drivetrain faults stemmed from the EGR problem rather than the gearbox. Your BMW dealer likely did not investigate the issue thoroughly, but rather formed an assumption based on the error messages they retrieved. While there is a possibility they are accurate, I assume that the most of us would estimate it to be below 50%.

It is commendable that they successfully executed your recall; we only get biannual correspondence informing us that they do not anticipate the vehicle igniting.

Clearly, I failed to push the Reply button after all.

If it is an Aisin automatic gearbox, it is likely that the gearbox is defective, since it is notably substandard. Before exploring choices, I will definitely have another individual connect BMW diagnostics to get a second view.
