troll alert, seems fishy

[AlpineG05]

yeeeeah 8800 rpm? if my dealer told me that lie i would go insane.

[D335I]

A blown engine in a new car is somewhat uncommon and should be subject to all kinds of questions threats etc...

Get your facts together, demand proof and be ready for a fight its all business to them.

If you made a bad downshift and it blew the motor I would think there would be damage or ware to the gears, thats a lot of force.

Cant believe a new motor is 19k thats assuming you need everything. A block cant be 19k and you should be able to reuse external parts.

Some forged parts and turbo upgrades may an option if you end up buying the car.

Maybe an alternative would be a E46 M3 motor with a turbo or SC would take some work but may end up being cheaper and would be pretty cool.

Hope it all works out for you...

the synchros should really prevent extreme downshifts. I've driven manuals since I was 16 and always had a vehicle that would grind to prevent extreme downshifts. I noticed these transmissions can go easily into gears even though they shouldnt go into gear (3rd gear while going 80+, granted I didnt release the clutch at these speeds) If the ECU datalogs the MAX RPM into flash memory, I would hope our wonderful code Guru's could find a way to find the memory location this data is stored and clear it. I've made it a point to only take my car to the dealer and no where else....If I ever ran into this situation I would have them prove it by showing me a date that the MAX RPM was reached to prove it was indeed me driving the car....In my situation, I bought a used 335i from carmax....so I've that MAX RPM didnt have a date next to it, I'd blame it on CARMAX.

On a side note...I think there was another case of this that happened on an M3 and the dealer printed out the data to prove the high RPMs. Good luck with your case bro, BMW is just trying to save there own ass, in the end, they dont give a fuck about the customer and try to fuck them every time. This is the first BMW I've bought, and will probably be the last one.

hope I have enough credibility here for you to believe me

[mkPOTO]

not to be a jokester but what if it the guy who was bouncing off the rev limiter in that video for break in..


if not best of luck you should complain and get them to show you proof

[Tortfeasor 335xi]

The first thing to do is to get BMWUSA involved and work with them towards getting this covered by warranty. If they persist in this you get a lawyer and pursue legal means of protecting your rights.

[onefastman]

The first thing you do is get a lawyer, explain to him how things work with the car, have him go with you to the dealer, keep your cool, be nice, and just observe as he requests information. Being nice will get you more info to use against them. Also it would seem that the clutch would likley slip before it would allow for that much force to be exerted on the engine; I dont have the exact specs but if you shifted from 70mph to 1st or 2nd gear the force would be eneormous and would result in something breaking before the engine (drive shaft, clutch, transmission, etc).
Long story short getting upset now is not going to do you any good. Just keep your cool, do your best, and things will work out. Best of luck man.

[Spydeputy]

lets put the name of the stealership up for view, that is jerking ur chain.

[Potty_Pants]

A couple of things...

1. We know the ECU is PERFECT w/o any flaws.... NOT
2. The dealer/service/tech needs to buy christmas presents... dont trust them.

good luck !

No, if you mishift no amount of electronic limiting will stop the mechanical pieces of the engine from reving that high regardless of what your tach says.

It's not like a motorcycle where your back tires will lock up at high downshifts. In a 3000lb+ car there will be no locking of the back tires. Your engine will give much sooner.

[TurboSid]

yea electonic rev limits wont do shit for a mechanical over rev. if anything the rev limiter is good to stop people from accelerating past redline, but when a misshift occurs there's nothing stopping the rotating assembly from over reving.

Ever heard of a mechanical over-rev? That doesn't appear to be the case here, but technically there is no computer that can keep an engine under the rev limiter in a missed downshift situation.

[Zeph]

Sorry but I have to go with a +1 on the money shift. There is no other way to hit and/or log 8800 RPM's. Probably racing and went from 3rd @ 6500 to 2nd gear... or 4th to 3rd. I would ask for proof and try to fight it too but I just don't see any other way (and neither will BMW). If they show you proof I would drop it there because further legal action will just cost you money that you won't recover or win back.

[eurodriver]

Yesterday when i spoke with my service advisor he stated a service tech from BMW North America came out and actually looked into a "black box" that shows what caused the car's engine to blow. Thats what he claims shows that i hit over 8000 RPM's. My service advisor told me I had to take this up with BMW of North America. I called them and they said it was up to thier dealer and service tech. There giving me the run around. My car is a Manuel and i know better then to go from a high gear at a high speed and down shift. I did not do that. i did go from 1st to 2nd and then to third pretty fast but not red lining it. The highest i have probibally ever gone on RPM's in this car is 6000 max; and i really doubt I did that. This car has NO mods and ever since i put the rims on i do not even drive fast. Anyone know of a good auto attorney to fight this matter in Southern California?

[Rob@RBTurbo]

what exactly is "blown" on the engine? I can see the mechanical over rev happening, but cant really see what it couldve "blown"- did the valves float and hit the pistons? If so that wouldve done instantaneous damage. You would be left with very little to no compression in at least 1 of the cylinders. Another long stretch would be a bent rod. I really dont think the lubrication or bearings wouldve taken it that badly.

Also, as stated before, make sure you get the proof that they really have data suggesting your vehicle has seen the stated RPM.

Reminds me a lot of the infamous money shift on E36's.

[migue90]

poor manuel

[Canadian-eh]

Valet parking??

[David1]

You can do the money shift and have no imediate ramifications and forget all about it. It can take a few thousand miles for damage to show or be instantanious.

[Ricky Bobby]

If you went to downshift...say from 5th to 3rd and managed to push it into 1st...then the engine WILL go to 8800rpm mechanically. This is known as "the money shift"

[BavarianBullet]

If it's blown, what mechanical failure is BMW claiming- spun bearing, dropped valve, completely grenaded bottom end etc?

Based on your description the engine just made some minor noises and cut out. If you really mechanically over-revved or otherwise got it to 8800rpm and it actually failed there, the failure would probably be a bit more spectacular than that.

I guess it could have hit 8800rpm from an over-rev, lived a little while on a spun bearing and then seized up later. Any other info you could provide would be helpful.
