New X5M owner, advice?

I'm in the process of selling my 2008 E90 M3 and buying a 2011 Carbon over Silverstone X5M with every imaginable option (Premium, Technology, Premium Sound, Cold Weather, Driver Assist, Ventilated Seats, Rear Climate, Soft Close Doors). Can't seem to get enough M! Curious what issues have been commonly seen with the X5M, so I know what to keep my eyes open for during the duration of the BMW warranty. I've seen the recent thread re: drive shaft. What else? And what do I have to look forward to? Don't get to pick it up until next week...

A few things come to mind...

-Leaking fuel injectors (search for this thread)
-Battery can drain quickly, but will be covered under warranty
-Make sure you get an alignment initially to prevent excessive/uneven tire wear. Tires aren't cheap for these things! You can probably negotiate this into the deal with the purchase.

Get the alignment to specific specs/values ... don't just say "alignment, please" ...

The BMW spec is too broad and will result in poor tire wear.

Interesting on the fuel injectors. Does anyone know the history? Based on the thread I found, it looks like BMW has gone through several part #'s… wonder what the deal is there. For the battery, this was a known issue with the E9xM3 too and BMW essentially blamed drivers for not commuting far enough on a daily basis to keep the battery charged up… wonder if it's the same thing. And yeah, I'm in Colorado, Land O' Potholes. Alignments are a MUST.

HPFP from driving hard or normal? Curious since I'm coming from NA to turbos. Can you expand on the suspension components issues - what components are failing?

Re: injectors, from what I've seen on here it seems like the overwhelming majority of failures happen on cars that use 91 octane. Haven't seen many using 93 from shell or BP with failures (myself included). I'm at 40k miles now and still running on original injectors.

No issues with HPFP on mine, haven't heard of this being an issue with many others either.

Timing chain, only one person I've seen on here have to replace. Look for Jimshorts he made a thread about it. Looks pricey and not looking forward to that repair.

I think the battery issue is hit or miss on the E70/E71. You either have a car with a draining battery or not (mines been fine since day 1), prob best to see the service history and see if its been addressed or not.

Try to test drive the car without the radio on and listen for creaks or bumps in the front of the car. Some suspension components tend to fail premature on these cars due their size/weight and its desire to handle like a sports car at the same time

hpfp was just a fluke i think..probably not something that is generally problematic.
Suspension: control arms, strut mounts, sway bar end links, all replaced recently after about 70k km.

apparently they are also replacing the muffler, due to a rattle in the vacuum-driven exhaust valves when not in M.

Awesome. 91 is the highest we can get in Colo... unless I go to the track and mix 91 with 101. Are they getting clogged? Wonder if a different injector size would keep them clear (a la 24# injectors in my E36 racecar).

Yeah, that was one thing I was going to ask my local dealer to do - pull all the service history so I know what's been done.

My E90's suspension is pretty loud, tie-rod ends clunk around. So at least I have something to compare it to.

Thanks for the response, really appreciate it!

bud, care to elaborate or provide more ref details on the 91 vs 93's impact on injectors?

we have just got 93 in town and would like to understand if there is ROI other than simple peace of mind in using it.

Thanks in advance

Like I mentioned its just what I've observed from what other owners have posted on here. There is no definitive proof that 91 octane is causing the injectors to fail. That said, this isn't a cheap SUV. If you have access to 93 I wouldn't put anything less than that in it, its really chump change when comparing the price of 93 to 91. Now if its really out of your way than thats understandable but I'd never put 91 in any of my cars (luckily we only have 93 here in the michigan). Plus you make max power with 93 octane so why not make the most power out of the beast you got!

From what my SA (who is a good friend) tells me that constant short commutes with the car not really getting up to temp is the biggest cause of issues in the TTV8's regardless of X5,X5m,750,550. He states that HPFP, injectors and oil burn is 3 biggest issues which is constant on short commute TT's

Got it Saturday!


It's in really great condition - big thanks to Motorwerks of Barrington (just outside Chicago) for delivering a beautiful X5M to me. Carbon Black is a gorgeous color - love the blue hue in the sun. The Silverstone interior is completely unpractical... and I wouldn't trade it for anything else!

Service history report my broker had pulled shows NOTHING except regular maintenance performed, so I plan to take it in sometime in the next couple of weeks and ask for them to take a look at the driveshaft. That, plus two issues I've encountered so far: 1) Comfort Access isn't working for some reason (new batteries didn't resolve the issue) and 2) Slow to start in the morning (battery?)... and when it does there's a short but ear-splitting screech. No rattles/clunks/weird squeaks from suspension or rear latch, but there is some noise when turning from the center console.

Thanks to everyone who's piped in!

She's a beauty! From one carbon black to another, congrats! My best advice to give... get a monthly membership at a handwash-only car wash. Carbon black loves dirt!

Congrats! That "ear-splitting screech" you hear when starting has confounded me since I got mine in March. It sounds like a starter, only happens when cold, is very brief, and the SAs cannot replicate it. My car's at the dealer now, and they're keeping it another couple of days to try replicating it. I doubt they'll be able to. They did provide me assurance that if the starter or something related goes out in the near future (whatever that means, warranty expired yesterday, won't put this in writing), they will handle it since the problem's been documented multiple times. I've found nothing concrete about it in searching the forums.

I made a thread about this awhile ago. Since that thread, it's only made the noise once more.

Thanks - the "trying to start a car that's already started" is the same noise I'm hearing. It seems like there were a few theories in that thread, but nothing definitive. Were you able to figure out the cause? It's happened the last 3 days in a row at cold start. I'm in a heated garage (always 60+) overnight, so I don't think it'd be isolated to cold weather.

I have both, M3 and X5M. There are little annoyances with the truck, creaks and rattles over time that can be addressed by the dealer, especially the trunk lid rattle. The battery was replaced by my dealer in case you get pushback down the road. Also, if you run it in winter, get winter tires and cover the extended wheel flares with some invisible bra, they will be pitted like crazy with Salt or gravel - ask me how I know.

If you feel the truck suspension too bouncy try non RFT tires which could make it much more compliant. Oh yeah, and you will need lots of Gas, Gas, Gas......more than the M3 V8.

Turbo HPFP issues are hit or miss.

Yeah nothing definitive with the issue. I don't think it's a temperature-related problem. I think mine's only screeched on a cold-start scenario though, and it's never happened in a row like you've experienced. Who knows...

Does it only happen when it's really, really cold outside or does it happen at any temperature. Had a similar problem with an e46 M3 and it would screech big time when it was very cold outside and it was a cold start. IIRC dealer explained it has something to do with belt tensioners.
