What is a mileage discrepancy?
A mileage discrepancy is where the mileage displayed on the car's odometer doesn't match what's recorded on the National Mileage Register or other records and sources, such as the information recorded at an MOT test. It could be a sign the car is clocked.
If you want to be just a little bit safer, then you could consider a mileage check from a company like Experian. These make use of information “from a vast database of mileage resources, contacting previous keepers where appropriate and investigating any discrepancies when necessary”.
Sometimes the mileage discrepancy is caused because of the number of digits that can be displayed as the indication for the distance traveled. For instance, most of the cars have five-digit (99,999) or six-digit (999,999) odometers.
Do car diagnostic tools detect mileage correction? The short answer to this question is No. The car scanner tool cannot really access the vehicle's actual odometer reading. It just calculated the mileage based on the distance between the start and endpoints of the road that you take.
Request a vehicle history report to check for odometer discrepancies in the vehicle's history. If the seller does not have a vehicle history report, use the car's VIN to order a vehicle history report online. If you suspect fraud, contact your state's enforcement agency.
The law in the UK creates a grey area in which legitimate companies offering mileage correction services can operate. Essentially, it is legal to alter the mileage on a car but it is illegal to then sell that car without disclosing known mileage discrepancies to the buyer.
Whether you need to correct the mileage on a car title because of a mistake or as a result of odometer tampering, your local DMV will help you move forward. Make sure you correct the title accurately and fill out the appropriate paperwork.
As a general rule, you should assume that the average car owner puts 12,000 miles on a car each year. To determine whether a car has reasonable mileage, you can simply multiply 12,000 by its age. That means good mileage for a car that's 5 years old is 60,000.
It is possible to tamper with the vehicle's odo to make its reading appear lower than the car's true mileage. It's important for buyers to check for signs of an odometer rollback.

What does it mean not actual mileage?
N=Not actual mileage (the odometer is broken, has been replaced, or the current owner is unsure of the true mileage).
The odometer reading recorded on your title will be branded “Not Actual.” This could greatly diminish the value of your vehicle. Allow DMV to hold your title while you collect evidence of the vehicle's actual mileage. Evidence may include inspection records, maintenance records, and work orders.

Mileage correction is the process of adjusting or re-calibrating the number of miles your odometer displays on your digital dashboard.
An engine swap or engine replacement will not reset the odometer as the odometer doesn't just measure the engine but all of the components of the car. In fact, it's illegal to reset the odometer as it would not accurately reflect the age of other parts of the vehicle.
The Federal statute is quite clear. 49 USC 32703(2) says a person may not “disconnect, reset, alter, or have disconnected, reset, or altered, an odometer of a motor vehicle intending to change the mileage registered by the odometer.”
Look for the obvious. Some signs of tampering include scuff marks around the gauge cluster, a set of gauges or odometer that looks newer or cleaner than the rest of the dash, or a trip odometer or other functions that no longer work.
Report the mistake to the Driver and Vehicle Standards Agency ( DVSA ) to get it corrected. You also need to email proof of the mileage, such as a scan or photo of: an invoice for the MOT. an emissions printout.

Inconsistent odometer readings - possibly around-the-clock, wound-back or human error. The vehicle's odometer readings appear to go backwards (a later odometer reading is lower than a previous odometer reading). Some possibilities for this could include: The odometer has gone 'around-the-clock' and reset back to zero.
If a more recent odometer reading is less than an older reading, then the odometer may have been tampered with and ""rolled back"". CARFAX analyzes the mileage history and the sources of this information to indicate a potential odometer rollback or mileage inconsistency.

What does true mileage unknown mean?
A “True Mileage Unknown,” or TMU vehicle has an odometer reading that is inaccurate. Dealers will “Roll back” odometers to increase the value of a vehicle. A 30,000 mile car has much less mechanical wear and tear than a 100,000 mile car. Digital odometers can be rolled back in a few minutes using a computer.
It is illegal for a car dealership to roll back the miles on the car for any reason. There are certain odometer statutes in effect that protect the buyers of vehicles if the miles have been set back. Sometimes this means criminal charges for the company or person involved in this illegal activity.
Can you reset miles on a vehicle? No. In fact, it's illegal to alter or tamper with your car's odometer, especially intending to deceive potential buyers or sellers about the car's actual condition. Mileage is one of the primary factors being looked at during vehicle appraisal and determining its sale value.
Sometimes with digital odometers, you cannot see the mileage easily if the backlight bulb has blown in which case you have the option to mark it as unreadable. If you go back with a small torch, you can sometimes get it in the right position to see the mileage.
Forget it. No legal requirement for an odometer in a motor car under Con and Use. Not testable under MOT.

Will a broken odometer fail MOT?
The speedometer will only pass the MOT test if it is complete, everything is neat and tidy, and there are no fluttering, sticking, intermittently working, or dead gauges. Your best bet would be to inspect your instrument cluster meticulously. If you notice any broken or faulty gauges, get the unit repaired immediately.
