$21k is just the cost of replacing the short block reusing heads turbos etc

The only safety may end being to buy a new motor from BMW and have them install it. Good luck.

May have to eventually buy out the lease and call this your track car...

Sooooo…. There is no fucking chance I am paying nearly $30k for a new motor. It is a lease. I did mod it (stage 2 bootmod3, catless dp, ap intake). Warranty will not cover it.

My options? I have a couple… Rebuild the motor, or buy a wrecked car with a usable B58 in it. Dealer quoted me $7,150 for the swap labor cost if I brought them a used or rebuilt motor. I’d say a 3rd party shop could do that for $3k including the DME coding right?

So I think I can get this done for somewhere in the $7-10k range. Hopefully.

Damn, another B58 bites the dust with the cylinder liner plasma coating getting destroyed from fuel dilution. This coating is the B58's Achilles heal. There is no fix as the B58 doesn't run iron cylinder liners. It's a stupid design and those that modify B58s should be very careful and have a small fortune set aside for a short block replacement or used motor swap.

OP - Your cheapest and safest bet is to source a used B58 from a reputable company like LKQ, car-part, etc, and find an independent BMW shop to swap it in. The difficult part will be confirming that the used B58 is correct for a M240. I'm not sure what differences, if any, there are among the first gen B58s across the model lines with the exception that the B58 in the M240 has an M Performance tune which would be contained in the DME. Buying and swapping in a used B58 including the necessary coding for the valvetronic and electronic wastegate systems will likely cost around $9-11K all in. I would think there are a number of independent BMW shops in your area. I'd start there as they could likely source you a motor.

[WolfGTI]

The car is already logged for the engine failure and noted as being tuned in BMW's systems - he's probably going to have an issue on lease return.

PTWA is also used in the S58, as well as by other manufacturers.

If you are modding I would suggest regular oil analysis to look for indications of abnormal cylinder wear.

Also, cylinders can indeed be re-sprayed and this is becoming more common in the remanufacturing process. YMMV

Generally, this is one reason I went with a Dinan Stage 1 – not that I imagine there are any guarantees beyond Dinan's basic warranty.

It would have been helpful to provide that little tidbit of information in your OP (lease) so at least we could save the effort on posting a real response and just laugh (at your expense).

You are screwed! You just bought yourself a car! Dealer isn't obligated to fix it and without fixing it then the vehicle is unsellable, so you own it!

Washed cylinders? Hmmm, and how do they know that?

And yes, who's tune were you running?

Is a bad tuner that dumps fuel... Anyone can do that. But it may not be the tune, what was the commanded AFR, etc? Running lean dumps fuel, and some tunes early on had issues with leaning out on #6... What supporting mods were installed? Again, who's tune? Was it tuned "on car" or boxed... Blah blah blah...

Bottom line is you will be busy and spending some $, whether it's for a lawyer to fight the dealer or for a new engine!

Good luck!

Edit to add... $7k to do a motor swap is nuts! I'm sure you could find an indy shop much cheaper. Real problem is the engine, BMW controls this... Not sure what parts you could even get. I did read that the engine design left no room for cylinder sleeves either, so you couldn't even bore it out, sleeve it, replace rings, bearings, etc. and have a "built" motor... and quite frankly, I would imagine the wash effect if that's what happened wouldn't have been just a geeee it happened kinda thing. It would have been washing for a while, taking the line with it and whooola!... Thsi is why it's important to KNOW all the parameters of the tune, not all will even tell you and that's BS. In addition, I'll ask again, were you scanning while running the tune? Curious... If not, tisk tisk. If you were, you would have seen an issue maybe early enough to prevent the disaster.

See, even engine is different, every injector, every gas station... There's too many variables out there. And what boost were you running?

Just going to drop this here..

Hope your bank account can handle the damage.

[Sail Boat]

Wow, what a complicated situation.

I have no idea how leases work, but am I right to assume that the OP has no choice but to pay the $27k because the dealership owns it, very much in the same way if a tenant breaks a landlord's refrigerator?

The only way out of that is by purchasing the car from the dealership at market value for a similarly equipped, functioning 2019 M240i. Based on an average lease rate and 28 lease payments (based on join date), that's roughly $12k into a $49k MSRP, or roughy $42k at current market rates meaning $30k to buy out the car today. A used M240i engine is going to cost anywhere between $8k-12k (lesser B58s are a non-starter) and labor at my shop would cost about $3,000 plus outsourced coding at $1,500. All in, that's $44,500 - conservatively $46,000 - to get this car running again... Therefore $58,000 out the door with an independent shop including payments made. I assume the car could then be sold for slightly below market, or $38k for a loss of $20-25k.

Yikes. That's a hefty price to pay for a $500 piggyback tune.

But, that seems like a better deal than paying $27,000 to repair, plus a full 36 months worth of payments at $43,200...

OP... you're obviously young, I'd guess very early 20s, so you've got a lot of financial runway ahead of you. Everyone on this forum has made dumb decisions at some point, so don't feel too bad. Just no more cheap tunes or modifications on your future car and never on one you don't own.

[aerobod]

If there are any plans to mod a car it is definitely unwise to also lease it, unless you can be certain it can easily be returned to it's original state. This is impossible with any tune, as once flashed (or in the case of a piggyback detected) it is not possible to meet the lease usage and lease-end return conditions.

Depending on the strictness of the lease-end inspection, you may also have to ensure, for example, the tyres have the BMW "star" logo on them too, as even the same tyre without the logo doesn't strictly meet the lease return conditions.

Better to finance the car instead of leasing in the case of wanting to carry out mods to it.

[AleksanderSuave]

the long and the short of it is, you wont be returning this car to BMW at lease end, unless you plan on handling the repair through them.

Your best bet at this point is to decide now if you want to keep the car or sell it. If its the latter, get the cheapest engine swap possible done, and then ship it to some third party buyback service.

If you want to keep it, jump in the B58 groups and find a reputable repair shop. It may be worth your money to pay $500-$700 to have your car transported to a shop that specializes in b58 repair work, that can source you a donor engine AND handle the full repair without making you pay $10,000 plus. Maybe even consider having it built up, if you plan on tuning more.

[swc5150]

You can get a new (remanufactured) B58 for your car for $4,995 with 2 year unlimited mile warranty from Ghassen Automotive. I'd drop one of those in and buy the car at lease end. Perhaps this is the cheapest route?

Do not do that.

[XutvJet]

The OP is figuring out how to safely wrap the car around a tree at the moment.

[swc5150]

Why not? If a guy doesn’t have $20k+, aren’t options limited?

[pashad13]

[swc5150]

If Ghassan is so bad then find another rebuilder. My point was not to spend the $21k at BMW when you can buy a rebuild for a fraction of that.

[pashad13]

Hey guys. so here's the story (abridged version). My lease buyout was $27k, and carmax valued it at $41k. So what did i do? Bought it out, swapped in a used motor with somewhat similar mileage for just over $7k. All in all, was in it for that point at $34k. Then flipped to carmax for $7k profit.

God bless covid chip-shortages for covering my *ss with used car prices through the damn roof.

From there, bought a 996 Carrera 4s 6 speed coupe for 33k. sold the next month for 45k

then got into an old range rover, built it out as an offroad truck & sold it. Got myself in a 3rd gen tacoma, built it out, and now trying to sell it.

In the meantime, i have re-entered the bmw family as a new owner of a f31 328d m-sport wagon, with all the fancy packages and under 100k miles, for $19k. With 55mpg on the highway and the way gas prices are, i am a very happy man

so luckily it all worked out. but sh*t, what a mess that B58 was.......

Awesome that it all worked out!

You also dodged a HUGE bullet with that 996. Those engines very often suffer the same exact fate as your B58 did. Rebuilding those motors is $25k+.

Luckily mine came with a receipt for an IMS bearing replacement not too long before my purchase!

Thanks for catching us up on the story. You definitely lucked out with the nearly historic pricing of used cars during Covid. Nice job getting it all to work out.
