e92 m3 motor plan cancelled

[Hotclutch]

This is worrying for anyone considering buying a used M car with some plan left. May as well look for one without plan if this is the case.

Sorry to hear this man, it really kills the joy of owning such a car.
How can they attribute a current issue to something which happened so many KM ago when no problem was noted at that time. seems a bit touch and go to me.
I would definitely try another dealership.

They will have proof if they are claiming a exact milage of the over rev. The Fasta Data print out will show this. If you feel this did not occur get someone to issue them with a legal directive to provide the proof. A letter from a legal firm will suffice.
If you can remember this occurrence happening only other chance you have is to check if your car had the bearing recall done if it's from the early models that qualified. You then got to way legal costs vs repair costs.

Potential claims over a certain amount are referred directly to the regional motor plan representative. Since two years ago all M cars that go into dealers are electronically checked. This started due to abnormal engine claims prior to that period caused by the tuners.

Here is what a typical print out looks like on a V8 that has over reved. You can see the evolution of the software in it as the rpm limiter was raised.

So much for some tuners claiming that applying software is undetectable and won't void motorplan. I think the question that needs to be answered now for the OP is at what point the software was applied. Would be a bit unfair if he bought the car in good faith and did all the necessary checks wrt to mplan and now have to deal with this.

I think in the OP's case its not software that is suspected but a mis-shift.

 

[Hotclutch]

I dont see how a missed shift can cause a bearing knock. And if the factory limit was in place then how was the car able to over rev? Perhaps the OP bought the car unknowingly with software, that was not detected with the transfer of MP.

still sounds to me like bmw are sure of their claim. how can a mis-shift cause you to lose MP. if that were the case, there would be thousands of M car MP cancellations and it would be public knowledge. no-one in their right mind would ever buy a BMW. then again, i must admit to having limited knowledge on the subject, but it does sound all a bit weird to me.

:sorry:

I have to agree I can't see how a stock car with a rev limiter could destroy the engine with a miss-shift? This really sucks though and I can just imagine what an engine on the V8 M3 costs if the short block in my humble little N47 tractor came to 121k .. best of luck I really hope you can uncover exactly what happened!

Guys, read my post below.... Stock and remapped cars can overrev !!!

A manual can over rev, say if you change from 5th to 2nd - by mistake. (at high revs)
Even though you have a rev limiter, a missshift from 5th to second will force the engine speed to conform the wheel speed for that gear, as they are connected mechanically.

Cool my bad must have missed this.. Makes sense, I thought that you would blow the clutch or gearbox before you damaged the engine if you tried this?

Nope, it's the downside of having good synchros.

thanks for this. in that case i would never ever ever in my life ever buy a bmw whose MP stated this. one lapse in concentration and you have no MP for a very expensive car.

:thumbdo:

 

[Crash_Nemesis]

They call it the money shift...

Driving hard and shifting into 4th... suddenly the car screams and the engine over revs... OH SHIT... that wasn't 4th... that was 2nd...

This is how you over rev a car with a rev limiter... Mechanical over rev...

I don't believe I need to explain why it's called the money shift.

 

[Fordkoppie]

Maybe this is why BMW does not want to make a proper gearbox (read manual) for their M cars anymore.
It is to idiot proof their cars. Bunch of Americans.....:fencelook:

I was making an exaggerated case of 5th to 2nd, but say you are in a hurry, you downshift from 4th to 2nd at low revs, and miscalculate the anticipated revs, and you mistakenly overrev it to 9000 rpm. This is the more likely scenario. You many not see any damage immediately, but the ECU will log the over rev.

Am not saying this occured with the OP, just want to shed some info, on the mechanics involved....

 

[Demon tweaked]

ah makes sense, i know a couple people who shifted from 4th to 2nd and it was not pretty at all.

So it can be said that changing from 3rd to 4th and missing "4th" altogether isnt an "over rev" in this context as an example but rather a drastic "4th to 2nd" scenario based on what 444YYY said?

PS: i thought bmw only picked up rev and speed being changed with sw?

 

[SKYF]

Bmw picks up everything, they can even tell you how many times you farted in the car, at what speed and at what gear all this was done

 

[moranor@axis]

I have only ever had a money shift once from 4th to 3rd(was supposed to grab 5th)

lucky i felt it was not right before i let the clutch completely out so the RPM did not go off the clock... :flyfun:
