Bjork Bjowlob posted:Fellow E9X M3 owners - how graunchy are your rear diffs at low speed? I've been noticing more and more noise coming from the back during tight low-speed turns and was wondering if it was a sign that the diff is wearing out. It's specifically worse with a small amount of throttle applied, but it's present with no throttle as well. My E90 is totally stock when it comes to belt/PS stuff so I don't have much info there other than to say if you have the original parts throw them back on and see if you still end up with the noise. That would isolate the pump being an issue. For the diff, I believe there was a TSB update for the fluid used in early model year E9X M cars. Something to do with a different weight + friction modifier additive. If you have high miles then it could be time for a rebuild. Like Ether Frenzy said these take time to warm up and if you are doing tight turns at low speed you will hear a "clunk". I would inspect your rear diff mount bushings as well. Age and mileage might have had their way with those and the "normal" amount of clunking could be exacerbated by your diff moving around a lot more than it should. the milk machine posted:my e39 m5 is coming up on needing a clutch; my mechanic predicted it and it's started to noticeably slip in higher gears Do the master and slave cylinders for the clutch. Probably a rear main seal on the engine since you are already in there. Just buy OEM transmission and engine mounts and have those done at the same time. Compared to the cost of what you are doing it will not be any added labor time. I probably wouldn't replace the fluids if they are 10K miles and a couple years old. Definitely watch the cooling system. When one thing fails with that era of car it is worth it to just replace every single component (thermostat/housing/clutch fan/hoses/radiator/water pump). At this point I would just say stick with all OEM parts for that. They all have about the same life expectancy so there isn't really one component worth getting aftermarket "upgrade" because something else will just fail around that. Don't buy cheap non-OEM parts because they will fail sooner. The real benefit of having an actual M car and doing prescribed maintenance with OEM parts is that you will have an easier time selling the car when it comes time, and will be able to list at a higher price. A stack of receipts showing ORIGINAL BMW parts will make that so much easier. FCP Euro, Bimmerworld and Pelican are places to shop and compare prices. blk posted:Am I an idiot for considering a high mileage ZHP? Yes. I would buy an E36 M3 before I would buy that. Really tidy engine though, looks dry which is impressive.

I believe they are all clutch pack but differing R&P size, ratio and/or case size differences. I have a 2.81 that I need to install in mine. 3.15 is insane compared to the 2.56 I had before.

I don’t think they’re all the same diff, but my guess is they use similar technology/design and probably the same original fluid from the factory, and BMW’s quality department probably saw enough issues with the fluid in those designs to recommend a change for all.

Could smell some oil and saw it come out of the vents again this morning  Wonder if I rolled the gasket when I put the new valve cover on? It has been on for at least a couple thousand miles now, figured something would have shown up before now.

What is the real range you're seeing city / highway and then any serious drop for winter (Obviously East coast cold 31F vs prairie cold -15F) How do the seperate motors handle the snow and ice?

Got a flat and dealing with some tire availability issues while traveling. Can't be repaired. It's an X5 M50i with 22s. How sensitive is the car in going into limp mode or damaging linkages, transmission, etc? Tire shop seems to be concerned that putting on slightly different tire sizes, even a set of 4, would put it in limp mode. But they don't seem to actually know.

If it's a square setup size shouldn't matter if you do all of them. With a staggered setup I think you'd just need to hit the same overall diameter front and rear? e: definitely a little visible oil on the passenger side of the valve cover in spots. I'm gonna start with the PCV vent hose as I didn't replace that when I did the valve cover. I doubt it fixes anything though as there was a little suction instead of pressure when I loosened the oil cap.

These are staggered. 275/35R22 front 315/30R22 rear This is what tire rack says for it. The actual tires are the Continental Premiumcontact 6. https://www.tirerack.com/tires/Tire...performance=ALL The official answer is that it could only be replaced with a tire with the exact same dimensions. The unofficial answer was that it could be within 0.25 inches, but I am not confident of that's width, tire tread width, or height. The tire place wanted that in writing and the BMW dealership wouldn't make any recommendation in writing that wasn't the same tire/dimensions. I knew these were going to be somewhat finicky, but after this experience I am definitely going to be swapping my summer wheels/tires to something that I can actually get when needed. The low profile tire probably allowed the blowout to happen in this case, and I live somewhere rural enough that the extra sidewall will help with comfort as well. I'm surprised at what a clusterfuck this has been. I was even open to swapping all 4 tires, or even wheels and tires. The brake caliper sizing was an issue there. I think we lucked out and found a set of MICHELIN PILOT SPORT 4S that will work and can get here tomorrow. But that's like 48 hours to get a tire replaced and is the absolute best case scenario. Otherwise it's like a week.

They're probably talking about tire height, which will also give you circumference / rev per mile. If it makes you feel better, there is already a .2" difference in tire height with your current stagger.

I appreciate that. I feel fine, but apparently the tire place felt differently. And a real bummer that BMW is so strict about their tire recommendations, but I guess that's BMW for you. I'd be more understanding if it was a specific BMW part we were waiting on, but all this trouble over tires seems a bit much.

This is one of the issues with big weird size performance tires, they're not exactly sitting around even in cities full of car people in the actual size you need in a lot of cases. Triple AAA will tow you up to 100 miles if you're somewhere in the boonies that can't get the sizes in a reasonable amount of time/you're on a trip, but it sounds like you'll have the tires tomorrow so probably not worth the effort.

Yeah, definitely lesson learned on my part. I knew they'd be specific and finicky, but not to this degree. I probably could get BMW roadside assistance to help, but they'd likely want to tow it ~5 hours in the wrong direction to the closest dealer (even the dealer has a delay to get the tire), and at that point it just seems to make more sense to bring the tires to me. Appreciate the thoughts. If anyone has more to share, I'm all ears! Along with recommendations on wheels/tires to change to in the future that would still be good and easier to find.

It's a great car. I have the Edrive40, which is plenty sporty. I think in both cases of the 40 and the M50 the acceleration is better than advertised. I would have loved the Xdrive option as a great middle ground for power and range. I'm in Maryland and lifetime I'm getting 3.3 mi/kWh which puts me at about 260 miles of range and when I've taken it out to the beach (160 mostly highway miles) it takes about 60% of the battery so it mostly tracks. We had a cold snap here over the winter where it was 10*f and it took the range down probably to about 140mi on a 90% charge. I recall white knuckling it on the way home from a poker tournament that I won but was 60mi each way and was getting a lot of anxiety making it back at 2am with a 8% charge. I believe the Xdrive has better battery conditioning though which probably helps.

I have the stock 740M 20"s that came on the 2023 X5 4.0 M-Sport i got back in February before the 2024 LCI updates. They don't "Fill" the wheel gaps like the 22's do, but still look good to me and feel a bit more comfortable for sure. It came with some Bridgestone Alienza RFT's that are not great but not horrible. Thankfully, there appears to be quite a few tire choices in the 275x45 R20 size once it's time to replace.  https://g05.bimmerpost.com/forums/showthread.php?t=2045019

No poo poo there I was. Driving my e46 on a nice straight 2-lane country highway. Not a cloud in the sky. I was thinking to myself how happy I was with myself for buying it. A slower car turns off in front of me and I press down on the pedal to let the straight 6 work it's magic. Except the second engine goes above 2200 rpm it starts running really rough and the yellow SERVICE ENGINE SOON light comes on.

Looks like there's oil seeping from a few spots around my valve cover. There are 2 bolts I can get to without pulling anything off. One had a little room before hitting the torque spec... The idiot that installed it definitely used a torque wrench  . I ordered a new PCV vent hose as well as a gasket. When I do the vent hose I'll check the other bolts and see if that fixes my issue.

I finally went after my A/C compressor - I was worried it would be an all day thing. I guess I'm a proficient wrencher cause I had the old (dead, seized) unit out in about an hour. I got the new (amazon) unit in and bolted up and was connecting the coolant lines, when I realized I hadn't connected the electrical line yet. I went to plug that and found that my unit that bolted up correctly did not have a matching connector. Womp. gently caress it, I will simply patch in the connector from the old (dead, seized) unit.

Hello everyone. About a block from my house my 2016 M235i gave me a warning that I needed coolant, and well...It Has Happened. Something has sure sprung a leak. Luckily, I was close to home, but it still kinda sucks. It's only got 49k miles on it, and this is the first problem I've had. (aside from having to replace the washer pump, but that was like, $20 and 30 minutes.) I'll get into it tomorrow and see if I can find out what is actually happening here, but does anyone have any guesses? My gut says plastic radiator bits.

When that happened to Mrs Jackson's 335 it was the coolant vapor hardline from the upper radiator pipe to the expansion tank. $50 and 10 minutes to swap.
