Dang. Sorry to hear that. Would love to hear more detail if a post-mortem is done. Can't imagine that it would die without any prior indication from the oil analyses.

[///SY33]

Wow, very sorry to hear (I was considering buying your car a few months ago if you recall). Any idea what may have contributed to the failure?

[Sophisticated Redneck]

You might be able to get away with just new bearings and a crankshaft. You won't know for sure until you look inside though. Worth it to check out.

Curious as to what oil you were using and how many miles per oil change?

[bmwpower603]

Very unfortunate.

Was the vehicle running on stock ECU software?

Any recent services prior to the Rod knock?

A brand new engine is $19000 from the dealer. That is what I would do personally.

I have been considering an E71 X6 M for a while now and these scenarios make me say "hell naw."

And then I look for a Silverstone X6M and get pulled back in. Definitely conflicted.

If you find one that has fully documented maintenance since new; you won’t have any issues.

Also; preferably one that is stock. Or Dinan tune ONLY.

How about the Velos tune? How much power does the Dinan tune give you BTW??

Thanx

Performance tunes do not increase engine longevity.

These engine failures are not that common. I think this is the 4th case I’ve read about on the x5m. So it happens, but it happens to all cars. Especially when tuned and pushed when cold, too think of oil and etc.

Frankly if you want your x5m to last don’t tune it. If you want to mod it by all means but you’ve got to pay to play. Tuning means things break, the more tuned the closer to a garage queen you’ll have.

I’d only buy a 1 owner car, and with a good service history, stay away from 4-5 owner cars. The car had a problem, and clearly the owners couldn’t afford to fix it or maintain it so they punted.

WELL SAID. People would be much better off if they would digest these truisms.

The only thing I'd say is these statements not only apply to X5m's, but any car/truck for that matter.

I have no experience with the X5M... but the above is good rule of thumb for all used BMW's. More than 2 owners almost 100% of the time means "deferred" maintenance/repairs. Primary reason why they have such a bad rep on the used car market and with all the non-BMW specific YouTubers.

[X5 MAN]

Used BMWS are like hookers.
People buy them because they cannot afford new BMWs
Once they are unable to afford repairs, they get passed on to the next punter.

^With few exceptions, yes. Most of those exceptions are found on car forums and are gluttons for punishment (myself included). I have saved more than a few Bimmers from the scrapyard because previous owners drove them until they would drive no more. I just hate to see a good car (good interior and exterior) go to he scrapper because people bought them, who shouldn't have.

Good feedback from the latest round of activity. I purchased mine as a second owner and you really do have to keep up with the maintenance on these cars. Doing otherwise would be catastrophic, but it costs a pretty penny to be able to keep up. Regardless, I find that the E70 X5M hits the sweet spot based on my family's needs.

Agreed an i definitely took care of this car, and event went out of the way to have the oil analysis done, I was about 2500 miles from my next oil change, so pretty annoyed, but yea Lesson Learned always have your diagnostic tool in your car, and if you have a rod knock sensor trip, pull the car over and get it towed to get the bearings checked out.

How would you know when the rod knock sensor tripped? CEL and diagnostic tool?

Just wondering... Is that $19k just for the engine, or is that your estimate with labor? I truly have no idea.

Exactly I had a CEL, and while I was driving i whipped out my tablet and ran a check and it would keep coming consistently say rod knock sensor (1 and 3) and Carly said it was not a serious issue, i seriously disagree. So if you see this pullover get it towed to a shop and have them inspect and replace the RBs.

I was quoted $19k-21k for a new engine from BMW, and $3-4k for install (R&R), Ghassan has a pretty good deal with $8.5 rebuilt engine (W/$3k core, so $11k w/o, 4 month lead time) and $3k install.

I had Ghassan rebuild my X5M engine and it's held up well. It's been almost two years and about 10K miles. I had him upgrade the internals to forged and have since put a dinan tune on the vehicle. The process took a while, but I think Ghassan has improved since my rebuild.

Not sure where you are located but if you are on IG contact this guy https://instagram.com/gmi_autodynamics he is located in Cali.

He has fully rebuilt another members engine after it blew up, $10k for everything, removing engine, rebuild and install. I contacted him a couple years ago as I knew eventually my car would have the same issue as all s63 engines.
My wife went to drop off some stuff at goodwill a couple weeks ago and car died a block away from home. My friend who works on euro cars told me it sounds like a spun rod bearing. Luckily my x5m is not our DD and it's rare that it ever got driven. We usually drive our c63s amg so I'm in no hurry to fix the M, but I know it will be around $10-15k for a rebuilt engine and install. The ideal thing I would want is to put a s63tu engine and dme into the e70 to open up my options on performance but haven't had any luck finding anyone else that has done it.
