My 4S ST has done 10,722 miles. It says next service due in 17,650 miles or Dec 2026 (in MyPorsche 'Service Intervals'). When I bought it, there were 9,500 miles on the odo.

I have a PDF of a 111-point check from 31/12/24 that states 9,487 miles. It was supposedly serviced at the same time (I've seen a screenshot of the service history from the CPO) at 9,487 miles, but although the service book also lists 9,487, the entry is meant to be km. And the car itself says 5,899 miles on the PCM at service in the 'Smart Service' section.

Any ideas why there might be a discrepancy? I can only think there was a km/miles mix up at some point (5899 miles is 'about' 9493 km).

Should i worry about it? Can my local CPO change the milege value on the PCM as to when it was serviced (the CPO I bought it from is 300 miles away)?

In my previous car the smart service record of milage via the PCM never matched when it was actually serviced. Dealer tried couple of times to correct it but failed so I gave up and asked for a print out of the service record.
