Part of the current diesel MOT is a single rev to the limiter.
My first one blew apart in side and part of the 6th gear was rattleing around side the bell housing!.
Second one just had some sort of internal linkage failure not quite sure as I didn't want to pay out my own pocket for diagnosis. They refused warranty under the grounds I had a GSR induction kit and painted alloys
... not covered due to the ECU logging 251 over revs which in validates the box warrenty. Now if it was 1 or 2 times that this had been brought up then fair enough but with it happening on every box that goes it is slightly suspicious no? ...
A rev-limiter cannot stop over-revving due to down-shifting at too high a speed.An over-rev is when the rev limiter is reached. Isn't that a contradiction in terms?
I hadn't heard about this specific problem, but its a known fact that any manufacturer will try and get out of a warranty claim on any defect. So its only natural for Fiat to try and claim an over-rev caused the damage. If that is the case then their self imposed limit is in the wrong place. So should they recall all cars to lower the rev limit in the ECU? No.
Well spottedThe number was 255, and it's not that suspicious as that's the highest number a computer can store in an 8-bit counter. Once the count reaches 255 it must stop counting.

As already pointed out by ducasi that simply means the engine has been over-revved so many times that the counter has lost track. It would translate to extreme abuseMeh close enough. The point was that every time Fiat have used it as a reason to avoid paying out it has been the same number.
Pretty easy I'd think - although it would be a pretty dumb thing to do - and I certainly haven't got any intention of giving a demoI'm not surprised a Jtd would'nt have any logged, can you even hit the limiter in a diesel?
Why is it a "get out" if the engine has obviously been abusedFiat have been using this get out for years.
But it hasnt that is what we are saying. Fiat use it on every claim that has popped up on here. Do you not think that is even slightly suspicious that its the same for every box that goes?
Thought I hadWhat would be significant is if they never reject (or at least warn about) engines in the range of say 50-100 or 100-200 times etc. This would be statistically significant and might indicate a software glitch exists :chin:
Exactly soWhat we do need to find out is if FIAT are rejecting claims where the ecu has logged less than 255 over revs...

It might also help to find out what kinds of repairs are being rejected - are they just powertrain faults or drivetrain etc also ? How about copy and paste from people who have had rejected claims based on the 'over-rev' counter and what fault they had with the vehicle ?
This was the idea when I started the thread.
In the particular case I have started digging a bit deeper. It is claimed that the car had 3 over revs of 1800 milliseconds at 6500rpm on a Diesel. Also it emerged (much later although they knew it) that the rpm sensor had a fault. Still warranty warranty is refused.
Next step is hitting hard. But would help to get more cases together and it will go to the relevant authorities.
