2010 X3 3.0d E83

[Gert Moller]

Good day everybody.

I purchased a clean X3 3.0d in 2025, with only 165 000km on the odo at the time of purchase. The vehicle has full service history. It is now almost a year later. I have done a oil service with various filters, last year af the purchase.

I need to do the next service and need advice what do I need to look at. The gearshifts are smooth, it pulls like a train. This is also my first diesel vehicle.

I have read a lot on DPF, EGR and swirl flap delete with a stage 1 tune. Would it still be beneficial to do this and what are the real life pro's and con's to do this.

Any additional suggestions or advice would be appreciated.

Wow car looks super clean!

I am not too familiar with the M57 but probably have the vibration damper inspected for cracks, change coolant and brake fluid. I am not sure what the gearbox history is but might be too far along to get it serviced at this mileage (ZF will test before advising you). Also worth doing the diff and transfer case oils.

You don't have a DPF but definitely remove the catalytic converter and replace with a downpipe which you can read up on the benefits of.

Thereafter have an ECU remap done to disable the EGR and Swirl flaps you mentioned so you reduce the chance of them breaking and causing expensive repairs later on.
