BMW Low Miles - Mileage blocker risk

[jaisingh340I]

Dear Fellow Forum Users

I wanted your valuable opinion.

I won't say which dealer and exac model- but they have advertised a Diesel BMW 2019 with only 30,000 miles.

4 Owners - with the 1st being BMW.

My friend pointed out to me that this seems very low for diesel and its age, and suspects the milage may have been tampered with.

Is he correct in his reasoning to be suspicious or could this be overthinking things?

And is there is anyway a consumer can mitigate the risks of buying a car that has been tampered with, or is the only way is to buy the newest car possible? As this obviously comes with a premium.

Do the miles tally up with MOT's or service history?

I bought a 2002 Jap import E39 540i with 53k miles on it in 2023... Loe mileage can mean nothing if it's been a car that's been lightly used... No need to go cynical from the off

Due diligence is what's needed to begin with

First MOT 2022 = 23 k miles
THEN only shows MOT in August 2025 = 24,600 miles (+ 1500 miles)
2026 = 30,000 miles (+ 5700 miles)

Mileage blocker or not I would not touch a low mileage diesel with a stty stick.

A Carly ODB reader will check the mileage stored in the control modules around the car. Whether the mileage blocker has affected these or not I don't know but there are enough BMW diesels out there that you can afford to walk away from one that doesn't pass the sniff test.

I buy cars for a living, for dealers.

I would not buy that car.

Thanks Trevor

Do you suspect it's been tampered with mileage blockers ?

What mileage would you say a 2019/2020 diesel should have ?


Im confused on what happened as first owner was BMW who did the first MOT in 2022

But then there was no MOT until 2025... Which does not make sense as someone would not buy the car off BMW to not use it/SORN it


Then last MOT was this year

I can't comment without seeing the car, and paperwork.

But it's what we call in the trade a "story car"

There's a reason there was no MOT's, and the low mileage between.

Plenty of cars for sale out there, don't buy one that's got too many questions attached to it.

None of my dealer friends would entertain it, remember that when you come to sell it.

Presume you've asked the dealer why the MOT gap?

What did they say?

And if they say it was illness, car sorned, then a death, then keeper changes due to bereavement to sell. I'd need very solid proof of all that.
