Now if you think about this on a logical stand point the ECU regardless of why, when you change your CLUSTER will always keep the original mileage starting form ZERO! So lets say that the cluster was changed for god knows what i highly doubt it would of kept saying 49K "IF" and that is a big IF the ECU had an internal reading of 84k. So all in all i doubt you have any worries.

If your crazy about it take it to a diff dealer and have them scan the ECU for the "said" mileage. If it is diff from your cluster then well you were Banged hard by someone. If it is all the same cluster and ECU then move on with life.

Also make sure the letter does not say TIME FOR YOUR 89K Service..LOL!!!!!

Thats the onlyway a Nissan Dealer can sell a cluster...

ALTHOUGH, those of you who know of the NISMO cluster that is imported from Japan, you put that on, your miles are at 0, and you calculate your distance and speed in KPH...

ECU has nothing to do with the odometer...

I'll paint you a picture of what I think probably happened.

Previous owner has his car repaired and a new gauge cluster installed. Odometer starts at 0 again.

Years later he trades it in and the receiving dealership records the mileage. The owner forgets (maybe for his own convienence) about the odometer swap and signs the odometer certification with the current mileage.

Dealer submits the title along with odometer certification to the state department of motor vehicles.

In the meantime, you come along and buy the car. The dealer has no reason to suspect a problem with mileage and neither do you.

Some clerk with the state DMV is processing the title change and it pops up a warning that the mileage doesn't look right -it's less than a previous recording.

They do some investigation and find out that a repair was done and the odometer reset. They notify the dealer that the odometer certificate was false and the dealership notifies you.


If you had gotten a Carfax, you probably would have spotted the problem since they access the same records as the DMV uses and it would have shown a mileage discrepancy.

Find out the facts. Like I said before, a legitimate dealership is not going to risk their business on odometer fraud. There's a record of it and a paper trail to follow. Somebody got it wrong and I'll bet it wasn't the dealership that sold you the car.
