Bmw M6 640d

[Doretta Castoe]

Ive got a bmw 2012 640D (diesel) 130k km. I had recently bought the car from my brother so. ive known it to be problem free for a year. It has a full service history. It recently developed a knock in the front bottom end. When I looked into it I found that it was leaking oil from the front end seal, and it had sheared the brass seal and contaminated the oil. When I looked further I found that it had spun a bearing.

I had the car remapped (no other mods) shortly before hand the knock, well there was a bit of time between but I had very little driving for a while due to covid and working from home. Shortly beforehand noticing the issue, I also had the car out for a spin all warm etc. I gave it a hard pull tipping just over 250km/h

1. Keep the car, frequent oil changes, possibly monitor the timing chain with a scan tool (if possible?). To do this I would remove the map, and go to darkside development get a new remap from them, along with their fmic.

2. Sell the car and buy something else. I'm not too interested in in removing the remap and driving it stock, in my opinion any issue there will just take a little longer to happen if is no remap on the car.

What is it that could have caused this failure, I have read up and can't see much in the way of remaps causing this problem, but the high speed, hard pull seems to fit the root cause a bit more. I have yet to further investigate into the internals of the engine. But what are your thoughts on this?

I think the 640d has the N57 engine which unfortunately suffers from the renowned BMW OEM bearing issues which are usually down to quality, clearance and oil starvation issues. In addition the timing chain and tensioner suffers with lubrication issues. These issues also tend to raise there head around the 60-70k mark which aligns with your current mileage.

regular oil changes will help reduce carbon deposits which lead to build up and restriction in the galleries as well as managing oil temperature, it could be worth monitoring and increasing oil cooling capacity to help this.

Yes they do the job of thinning the oil and making it easier to drop it out and get rid of any gunked up oil - if I was to use a product to do this I would then run the car on a sacrificial oil and swap that out after a few hours of running to make sure all of the flush has been removed.

You can find that with a flush some of it stays in the system (in lines and coolers etc) which when you then add fresh oil dilutes it slightly. It is ever so slightly and I have never heard of issues coming from using a flush product but for me I would use two oil changes to be sure.

That said I would only do that to an unknown engine, so when you get yours rebuilt just keeping on top of regular oil changes should be enough to make sure it stays clean and fresh without deposits building up.

Also as Scott mentioned you can send samples of your oil off to be analysed to see what is going on internally, this will let you know if there is any excess of bearing material getting into the oil; as Scott mentioned would hint to oil starvation to the bearings.

it can also be a great tool for peace of mind, so once your comfortable with the oil results from tests; happy with the choice of oil you have made and you have data to back it up you can sleep easier if that makes sense.

And being logical for a moment, leaving aside the fact that we think the Gran Coupe looks significantly better than its two-door counterpart, the four-door model has much more interior space and it has proven to be better to drive in the past too, the longer wheelbase endowing the chassis with more stability without detracting too much from agility. This is, after all, a large luxury car with sporting pretensions, not a sports car with luxury pretensions. Hence we're not sure why anyone would bother with the two-door model. Sales figures around the world show that we're not alone.

So that's one decision we don't think will take too long. Next up, the engine. The 'entry-level' 640d is the absolute star of the line-up, regardless of how much money you have burning a hole in your pocket. It's powered by BMW's venerable turbocharged 3.0-litre straight-six diesel, which now produces 313hp and an astounding 630Nm of torque. The latter figure in particular means it feels fast from any speed in any gear. Effortlessly so, suiting the car's demeanour. Yet it also sounds great, animalistic almost, especially if you extend it. On top of all that of course it costs criminally little to tax each year and, if you have a light foot, you may see 40mpg occasionally. Honestly, there's little reason to choose the petrol-powered 640i or 650i, so tick the 640d box on the configurator and move on.

Yes they look stunning and really fill out the arches, giving the Gran Coupe's bodywork added presence. BUT (and it deserves to be in capitals), the ultra-low profile tyres have a ruinous effect on the ride comfort. On anything other than glass-smooth tarmac the firm suspension picks up on every little ripple and bump. On really poor roads it means an uncomfortable experience that really is not in keeping with the exceptionally high quality and comfortable cabin. So what to do? I'm torn and I'm only reviewing the thing; I can't imagine how an actual buyer must feel. The larger wheels really do suit the car in design terms.

Either tribe may institute such further original, ancillary, or supplemental actions against the other tribe as may be necessary or desirable to insure the quiet and peaceful enjoyment of the reservation lands of the tribes by the tribes and the members thereof, and to fully accomplish all objects and purposes of this subchapter. Such actions may be commenced in the District Court by either tribe against the other, acting through the chairman of its tribal council, for and on behalf of the tribe, including all villages, clans, and individual members thereof.

[A] plaintiff who merely claims that a defendant violated a statutory duty does not necessarily satisfy the requirement of injury in fact in article III. Instead, we hold that the crucial inquiry in such a situation is whether a statute that imposes statutory duties creates correlative procedural rights in a given plaintiff, the invasion of which is sufficient to satisfy the requirement of injury in fact in article III. In determining whether a given statutory duty creates a correlative procedural right, we look to the statutory language, the statutory purpose, and the legislative history.

Specifically, they claim that appellees 1) failed to submit to Congress the type of detailed plan and report required by 25 U.S.C. 640d-12; 2) failed to establish a uniform policy for the fair and equitable treatment of Navajos displaced as a result of 25 U.S.C. 640d et seq.; and 3) are purporting to carry out the relocation of Navajos currently residing on Hopi land in the absence of statutory authorization or in a way not in compliance with the dictates of 25 U.S.C. 640d et seq. They also claim that the United States 4) violated the due process clause by including a change in the method by which relocation benefits are determined in an appropriations measure, or, alternatively, effected a taking without just compensation by failing to compensate them separately for their habitation and improvements when determining benefit levels; 5) violated the equal protection clause by passing 25 U.S.C. 640d-10(h), which creates "a sub-class of relocatees who are the only Navajos eligible to move to the 'New Lands.' " Finally, they claim that 6) the Relocation Commission has failed to provide the preferential relocation assistance mandated by 25 U.S.C. 640d-14(f); and 7) appellees' fifth amendment violations constitute a breach of the government's trust and fiduciary responsibilities towards native American Indians

The Settlement Act requires the Relocation Commission to reimburse heads of households required to relocate as if they were displaced persons under the URA, 25 U.S.C. 640d-14(b) (1), and to "establish standards consistent with those established by the implementation of" the URA, id. Sec. 640d-14(c)

Of course, Benally can appeal a benefits determination pursuant to 25 U.S.C. 640d-14(g). See Bedoni, 878 F.2d 1119; cf. Begay v. United States, 16 Cl.Ct. 107 (1987) (broad challenges to Settlement Act procedures made in context of claim for money damages in light of benefits received pursuant to relocation), aff'd, 865 F.2d 230 (Fed. Cir. 1988). But were the broad challenges asserted in this case the only ones made in such an appeal, we would again lack standing because it would be wholly speculative whether we could redress Benally's injuries. As Walker illustrates, submission of an accurate report and relocation plan to Congress is not a necessary prerequisite to the ultimate award of relocation benefits. Thus, even were we to conclude that the Relocation Commission violated its statutory duty, we could not be confident that the Relocation Commission would alter its award in a subsequent benefits determination

The situation thus would be distinguishable from those in which we have held that parties may challenge agency action on the ground that judicial relief would make them eligible for benefits they otherwise would have no chance of being awarded. See, e.g., Bullfrog Films, Inc. v. Wick, 847 F.2d 502, 506-08 (9th Cir. 1988) (film makers and companies may challenge United States Information Agency's regulations governing certification of films since such certification is an essential prerequisite to obtaining benefits under the Beirut Agreement governing educational audio-visual materials). It would also be distinguishable from the situation presented in Preston v. Heckler, 734 F.2d 1359 (9th Cir. 1984). In Preston, we approved standing where an agency's failure to promulgate statutorily required separate and independent standards for evaluating the employment qualifications of Indians made it impossible to say whether, had the standards been established, the plaintiff would have been eligible to compete for a job as a social worker. See id. at 1365-66. Nonetheless, it was clear in Preston that the plaintiff had no chance of being considered for the position of social worker without adoption of separate standards. Here, by contrast, Benally would be eligible for adequate relocation compensation even if the Relocation Commission had failed to submit to Congress the report and plan required by 25 U.S.C. 640d-12.
