I don't think that's enough for me to spend $2k.

I'm going to go to the dealership tomorrow and talk to the Service Manager and see if I can get them to do anything. The way I see it, I buy a new car every couple of years so it would be in their best interest to work with me somehow. I don't think that's very unreasonable.

Any advice on dealing with BMW NA would be greatly appreciated.

Then start making waves in local media, they like stories like this, and BMW will hate it.

If BMW NA isn't going to help, then tow it to the road infront of the dealer, buy a big big ballon, paint it yellow, make it look like a lemon. Then make a sign letting all the would be customers know how many miles your car has on it and how much help BMW is being to you..

Guarantee that dealership would loose about 5K a day in sales. If NA doesn't stand up, the dealer would be obligated. THats what I would do. Not sure what town your in, but that may make the local paper and radio too.

It makes me mad just thinking about it. Sorry dude...

Those are both great ideas.

I'll see how everything goes when I talk to the service manager and then act accordingly. I'll keep everyone posted.

Find a used motor get it installed and move on. Mentioning future sales to the dealer won't mean much.

Mentioning future sales to BMW NA is what hits home. I've been a SA for 5 years, and whenever anyone reports to HQ shit goes down.

They understand the logic, one unhappy customer will detour six potential buyers (by statistics).

Sure, millions of cars sold - but when it becomes one in every 5 people who are completely unsatisfied with the company as a whole you will see car sales hit the floor.

If you put a hole through the side of your block you would have probably found metal on the ground... or if you're eastern european, you'll find a connecting rod.

The smoking gun is the rod. 2K seems like a lot to drop the oil pan and pull the remains of the bottom half of the rod and do an evaluation. Seems like that number (+/- half way to an engine install at the dealership) is being used to coerce you into just giving up on your claim.

You do have a leg to stand on if it's determined that the rod was improperly cast or suffered from fatigue cracking.

Sorry for the late reply, I've been out of the country.

The shop said that the failure was due to a bent rod. The only thing that could have caused it was a puddle I went through back in August so my insurance ended up covering the engine replacement. All in all, it worked out and I couldn't be happier. The fact that I drove my car with a bent rod for 7 months is a testament to the strength of the N54. That fact alone has me rethinking my "no mods" policy on this car.

I guess the moral of this story is if you're driving a car and hit anything on the road ie pot hole etc etc get a police report. It can always save you later. I remember when I did an engine swap on my 3000GT because I soon a bearing and told my insurance agent, he asked did anything on the road caused that to happen? I said no, he said if that was the case, my insurance would have covered it. At OP, glad everything worked out good for you.

Wow.
If the tech heads could explain how a puddle can bend a rod that would be useful.
Thanks!

Hydro lock in that cylinder due to getting water in the intake when crossing a very deep "puddle"/lake. It has happened a couple of times to others on the forums.

water is nasty to a motor. The hydraulic forces will surprise you. Here in Florida we had some heavy rains which lead to a lot of flooded streets. The local BMW dealership took in 114 cars during that week for hydro locked engines. My dealership I work at, took in 0. Regardless water plus engine equals a lot of bad things for pistons and rods.

Glad everything worked out for you OP, but that must have been one hell of a puddle. I've seen a hydorlocked NA motor before but the path to the motor is short. It happened to my friends Cobalt whose CAI was routed to the bumper.

With an NA it's filter, pipe, manifold, motor then boom and it doesn't take much. With the N54 the water has to pass the intake and filter, turbos, intercooler, and up the charge pipe before even hitting the motor.

You'd think with that amount of water that the turbo's would fail first seeing as it has to go by it first or actually if the motor was at operating temp that the turbo would evaporate the water before even making it's way to the motor.

Pretty amazing, actually.

Looks like I was right, huh?
