my 2003 330Ci engine got busted after a downshift. the exhaust valves got misaligned, and the pistons were damaged. the cost of repairs is around $12000, including replacement of valves and pistons and inspection of cylinders

i only got 14000km on the car since driving it off in november.

my dealership said that this is not covered under warranty, and the cost of taking apart the engine for analysis is already $900 right now.

i have 3 choices:
1. put the engine back together (it still runs, but with a high risk of further damage later on)
2. repair and replace the parts for $12k
3. sell what is left of my 330 engine and replace it with a new/used m3 engine

since i'm gonna pay $12k to get it fixed, i rather spend more and get an engine swap

anyone here knows of or have an E46 M3 engine for sale? My dealership quoted me for around $25k for a new one. Any comments or suggestions?

thanks.

dealership explained that since it was a manual downshift at such a high speed and the impact was so hard that caused the severe damage, BMW Canada will certainly send someone down to investigate and most likely won't be under warranty.

i'll call BMW Canada and see wut they have to say.

anyone experienced this before?

how much of a downshift did you do? 5500rpm in 5th to 4th or what? musta been quite a major downshift to **** up the pistons and most likely crack/damage the cylinders

There're many cases like that in E46Fanatics and those people DON'T get engine replacement under warranty.... because of mis-shift ... you may take the chance of calling BMW Canada but I can see the chance is dim ....

If they don't want to replace your engine under warranty ... get a new engine !!!
a M3 engine would be great !!

Did you go from 5th to 2nd? If you did, BMW will do nothing because they will not warrenty any damage caused by a miss-shift.

That's pricey. If you decide to get the engine rebuilt I can recommend some better car shops. BMW is a total rip off. That price is at least 3 times the price of what other car shops will charge. Just to take the engine apart for diagnoises usually runs around $300 at car shops.

Does the e46 have similar onboard self diagnostics like the e36 does.

On the e36, you can run through a routine that lists faults codes like if the engine has ever over heated, or if the engine was ever over revved. I believe you use the trip odometer reset button for that (it's been a while since I tried it).

On the e46, I believe it involves depressing the accelerator 5 times, but Iím not sure if it will indicate an Over Rev.

Iím just wondering if an over rev was ever flagged on the ECU. That would determine if itís under warranty or not.

The only one who can do a proper diagnosis on the car is the mechanic from bmw canada, hes the only one who can do a DME on your car to see what happened... it will tell you exactly how long the engine has been over its redline since the engine had 1km on it..BUT IT WILL NOT TELL YOU WHEN it was over revved!!!!!!
you shouldnt tell them you mis-shifted though, jsut say you dont know what the hell happened..
AND when he says its been over revved, tell him this
THE CAR HAS (XX) KM ON IT WHEN I GOT IT, HOW THE HELL DO I KNOW A SALESMAN DIDN'T OVER REV IT, OR A TRUCK DRIVER THAT LOADS IT ON/OFF THE TRUCKS.
believe me, its a good argument...

if you end up going the new engine way, you can find a e46 m3 engine on ebay for around 5-10,000 u.s....or call bavarian motor exchange, turner motorsports, or simple call the wreckers...

get a lawyer, your car has only 14,000 on it. I misshifted before in my 320i and nothing happened, I went from 5th to 2nd. BMW has to cover man or take it to court. It 's a ****ing high end car, you don't pay over $60,000 for a car that will literally break at 14, 000km

Here is exactly what the DME shows, but its in german, sorry its all i could dig up while im @ work..
it shows the maximum speed this car ever reached was 209 km/h
the max rpm ever reached was 8460, and since 1km, the car has been @ 8460 for 13.1 seconds, not neccisarily all at once, could have been 50 or 60 times, that had added up to 13.1 seconds..
anyone else that can understand what the hell this thing says feel free to comment...

SMG330? i thought SMG prevents downshifts that will rev to high and it waits till a safe engine speed?

Hate to be the bearer of bad news, but I think you are out of luck. I hope I'm wrong.

Classic 'Money Shift'. No warranty...

2nd needs a better lock out.

Good luck.

argue it, one thing for sure....DONT SAY YOU MISSED THE ****IN SHIFT ARE YOU INSANE! they will right away tell you your out of luck....
argue it and completely ignore the shifting scenario
good luck

P.S. seems like that RSX premium scenario where his pistons were turned into eggs

i think rolled_out has a good arguement for the dealer.
strange my friend showed me on 403 exiting the hi way on his 2003 325i from 4th at 120km slam it to first and clutch didn't engage untill the rpm went lowered. .. is that somekind of new system put in it ?

I dont know where alot of you guys are coming from and getting your info but if he mis shifted he is out of luck.

The dealer service manager and Bmw rep are not idiots. They know when you have mis shifted and they will definately not going to buy the story that you were driving the car and all of a sudden I heard noises.

Yes the DME from 96+ OBD II will store the max rpm and for how long.

The driver normally can not over rev as it has a rev limiter.

So if you have a rev limiter then you can only over rev by a mis shift.

There has been many E36 M3 that has mis shifted and the damage has never been covered under warranty.

You can not say that the delivery person or sales person did it as you dont get bent valves 12,000km later.

When you over rev and bend valves you will hear it right away not tomorrow or a few weeks or months later.

Bmw will stand strong as they will document that they have no other issues with manufacturing process resulting in failures in valve train being bent under normal use.

I have read on other boards that dealer read some forums and then they are not liable for covering damage under warranty if it was driver related.

So you should not have posted saying that you mis shifted. This is not to say that they are onthis board but you have to be carefull when it comes to warranty as most dealer will try and screw you out of it.

Sometimes if you and the shop foreman or service manager or friends they can try to help you but not when it comes to a new engine under warranty Bmw Canada is going to want to see that motor. :(

If you have to pay for the repairs dont use the dealer there are many shops that can do the work.

They are correct in saying and I would not be driving the car as you can damage more pistons and the cylinder head. If the values breaks off and gets into the chamber its lots of $$$

To buy the exhaust valves they are not that expensive but maybe the pistons are.

Remember dealer loves to change parts withour using old ones if they can be used still.

The E46 M3 spinning a bearing is a different story and Bmw has increased the warranty on those motors.
