Timing chain for the 2014 X5

[Anabroo]

During a recent repair, my technician said that the timing chain on my 2014 X5 3.0 L diesel SE was "loose," albeit not critically damaged. I have completed 224,000 km, and it has not yet been changed. He now asserts that it is unnecessary to do the task since the N57 engine does not have timing chain issues. I suspect he may be reconsidering his decision due to his undervaluation of the job. Do you have any recommendations?

One is not obligated to honour a quotation till the commencement of the task, hence it is improbable that this is the explanation. Consider obtaining a second opinion.

Indeed, it may be true; I just want to ascertain if other BMW consumers would find it bothersome to change the chain. No discernible indications of rattling or similar disturbances are present from the engine.

It depends; if you have invested a substantial amount and want to retain it, then I would recommend having it serviced, similar to the maintenance of the gearbox and transfer case.

[Anabroo]

Thank you, and indeed, I want to retain it. My technician has also advised that I do the ZF gearbox service for 950 euros as part of 'future proofing' the vehicle. Is it what you refer to as the gearbox and gearbox case?

N57 still operational; I completed a task last week.
