M340d with low miles

[Motoman]

I apologise if this topic has been already addressed, but having had an exceptional M340D Touring for the last two years, I am becoming concerned that our low yearly mileage may lead to future problems. My wife mostly operates the vehicle, doing a daily round journey of around 8 miles to her business, with occasional longer excursions on weekends, resulting in an annual total of 6,000 miles.
This week, during the 30,000-mile service at BMW, I expressed my concerns about the DPF/EGR, only to receive contradictory opinions: the service manager indicated that short journeys are detrimental to the vehicle, while the technician who performed the service reassured me that modern diesel engines do not present significant issues. I am becoming increasingly perplexed and would value any sincere feedback to guide me on whether I should consider exchanging my car for an M340i, which, while not the worst option, may not match the versatility and torque of my current vehicle that we truly appreciate.

The optimal approach is to operate it at a continuous speed of 40 mph or higher intermittently; this will allow it to reach optimal temperature, and you will see the regenerative effect when the exhaust sound changes somewhat.

If it is not malfunctioning, do not attempt to repair it.
If, after two years, you have seen no problems with the DPF being obstructed, it indicates that it is reaching sufficient temperatures and doing enough passive regeneration to remain unobstructed.
An economical BMW-specific code reader will provide back pressure readings and indicate the last active regeneration, making it a valuable addition to any BMW glove compartment.

The EGR may ultimately obstruct the intake manifold, but it will just need cleaning in another 50,000 miles.
A clogged DPF and a blocked intake are only cleaning tasks that will not damage the engine.
Disregard the computer's recommendations for service and do an intermediate oil change annually or every 10,000 miles at most. The expenditure on oil and a filter is a prudent investment.

As already said.
The infrequent extended run on weekends should suffice.
If there were an issue, you would have already seen a notification on the dashboard.

I appreciate your insights; they are very beneficial in alleviating my concerns and assisting me in the choice to retain our vehicle.I would consider exchanging it for an M340i one day, only to appreciate the amazing B58 engine.

Generally, service managers lack understanding.

I accumulated just 6,000 miles annually in my 640d. As long as one undertakes a 20-minute drive sometimes, my journeys often lasted 20 to 30 minutes three times a week, supplemented by other short excursions. The vehicle remained in optimal condition, as I consistently monitored its status via diagnostics.
