2011 X5 M injectors and plugs bad at 42K miles?

I am a new member to Bimmerfest, and I need some advice from the Bimmerfest community. I purchased a used 2011 BMW X5 M from a longtime friend and client of mine. The X5 M has 41,300 miles on it, and as I was about to drive off in the X5, I was told by the seller that the previous owner had installed a chip to boost HP to 660! The very next morning, when I started the X5, the check engine light came on. It was steady yellow, and the engine was idling smoothly. The info screen said there was a problem with the emissions control, but it was safe to continue driving unless the Check Engine light started to blink.
I figured I'd check the code and reset it. I drove the X5 out of town, and it ran perfectly.
The next day, when I started the X5, the engine was hard to start, and barely idled. I received the major engine malfunction/reduced power message. I drove it in the reduced power (limp home) mode for 7 miles. I parked it, and ate breakfast. When I returned to the X5, it started right up, and idled smoothly. No engine malfunction/reduced power message, and it ran perfectly. I drove it back to Austin, getting 19.5 mpg with only the small, steady check engine light. I checked the code for the check engine light, and reset it. The next morning (day #3 of my ownership) it didn't want to start in the morning. It started, but the check engine light returned (steady) and the engine malfunction/reduced power message was there again. I drove it for about 10 minutes to get the temp up to 210. It was still struggling and smoking. I parked it, and shut it down. I recalled what had happed the previous morning, so I tried to start it again. It started right up, and settled into a smooth idle. No more check engine light, no more engine malfunction/reduced power warning either. I drove it to work (25 miles) mostly freeway, and it worked perfectly. Five hours later, I tried to start it to go to lunch, and it went into rough idle, reduced power mode.
I took it to a local BMW repair specialist who has a good reputation, and asked them to diagnose. They inspected using a BMW Technical Bulletin and found that I need to replace all eight fuel injectors, all eight spark plugs. With parts and labor, they tell me it will cost a little north of $4000 to fix, and they'll need almost two weeks to get the repairs done.
I find it hard to believe that the injectors have failed at 42K miles?
I did some searches on Google, and it seems there are plenty of BMW injector horror stories out there. Have any of you Bimmerfiles had a similar experience? Within 2 days of ownership, I am facing a $4 to $5K repair bill on a vehicle that has been properly maintained at the local Austin BMW dealership. The seller maintains that the X5 was not exhibiting any of the problems that I have experienced while he owned it. I am finding it difficult to believe that the injectors and plugs failed as soon as I purchased it. I put over 500 miles on it over the first two days, and it did act up on the morning of day 2, but that issue went away as soon as the engine warmed up. I love the X5 M, it is a fantastic vehicle. I am just blown away that I am now facing a $4000 repair expense that the seller was completely unaware of 5 days ago. Any thoughts, advice or recommendations would be greatly appreciated.

Yeah, the earlier index injectors had problems. The index 11 and later injectors are an improved part. It's unfortunate, but you did buy a $100k vehicle out of warranty. It may be new to you, but its been on the road for 4+years now. The money you saved over new is now being applied to repairs. $4000 is dealer level or higher pricing, you might get a quote from the dealer. They should be able to knock it out in a day, not 2 weeks. Make sure whoever it is, is competent. The injectors have to be calibrated to the DME(engine computer). There are also some very important grounds disconnected during the repair, if left loose you'll need a new DME. If the injectors themselves aren't properly secured you'll need a new cylinder head(s).

Also thought I would mention that the injectors are direct injection. Since you were wondering how they could fail. They operate at 10-40 times the fuel pressure of a traditional port fuel injector. They also deal with the extreme heat and pressure of combustion. A traditional injector does not.

Why is the vehicle out of warranty if its a 2011 and less than 50k? Is it early 2011?

Thank you for the information. My mechanic tells me the new injectors are gen 3 and are much improved over the gen 1 injectors.
I'm looking forward to getting the X5 back, and to building my trust in it. The first week has not been so Bueno. I purchased it for a reasonable price, given it's extraordinary attributes and it's original MSRP. I am hoping that this was an isolated failure, and that the X5 M will prove to be, like my previous BMW autos and motorcycles, dependable and fun to live with.

Thats a great question! The Repair shop called the dealer to check on that. They told me that it was out of warranty since May 2014 due to its build date in April of 2010. They seemed sure that there is no more factory warranty. But, I need to revisit that subject. I didn't buy it new, and was told by the seller he was considering purchasing an extended warranty before he agreed to sell it to me. I did not purchase said warranty, largely because It broke before I could even get to the DMV office to transfer the title! The seller was told the factory warranty expired too. Is the factory warranty 4 years or 50K miles?

Doesn't the warranty start from the in service date? Not the build date?

It was probably an ordered vehicle, not one off the lot, or possibly just sold right away. It was made in South Carolina in April, and delivered to the customer in May.

To the original poster, ignore the 15k mile oil service indicator. Change it atleast every 5k with synthetic. These engines have problems with seals on the turbos and valve seals leaking. Changing the oil more frequently is all you can do to slow their failure.

Mein Auto: 2011 X5 M
I was told by the seller, who purchased it used from the original owner, that the X5 M was ordered by the original purchaser. The 8 injectors (gen 1) were replaced yesterday with 8 new (gen 3) injectors and 8 new spark plugs. The engine was started and ran rough and smoked for 10 minutes before eventually smoothing out. The tech discovered two fuel line leaks at the injectors following the test engine run. I was told late yesterday that the tech wants/needs more time to test and synch the new set of injectors with the engine computer. They promised to have the X5 ready on Monday. The repairs are being made by a local Austin BMW specialist rather that the Austin BMW dealer. It's a little too late at this point to take the car to the dealer, so I will wait a few more days until we find out if the repair tech installed everything correctly. According to you prior reply to my original post, there are several steps that are delicate and could damage the engine computer if not carried out in the correct sequence. I'm more than a little worried about the outcome at this point. The car has been in their shop for two weeks already! We'll see how it all turns out next week I guess? Thank you for your advice and comments too. I appreciate your input and perspective.

New X5M owner, and any input welcome. I was quoted ~4k to change all 8 fuel injectors on my X5M. Currently only have 51k miles on it, but I am experiencing only 10mpg. Wondering if this fuel injector replacement will improve the gas mileage, has anyone experience any gains on gas mileage by changing the fuel injectors?

I had to replace all 8 injectors in my 2011 X5M at 42K miles. No warranty (time) Cost $3800. Gen 3 injectors working well so far, no further starting or running issues.

My in town mileage is around 15 mpg. Highway/cruise at 70 mph it gets up to 20 mpg. If your injectors are failing like mine did, be careful that they are not dripping fuel into the combustion chambers while the engine is off. My oil supply was found to be saturated with fuel when the injectors were replaced. Prolonged use under that condition would be a bad thing.

Thanks for the quick reply. I will have to investigate per your recommendation.

Just curious, the 15mpg's is that a combination of city and highway or just highway? I'm trying to justify the cost of potentially going with this fix vs. potential gas mileage saved.

Did you start getting errors on your engine or a check engine light when you became aware of this?

hsc1102, I'd try pushing for BMW to warranty the injector work after the known issue with them and the subsequent N63 recall campaign or customer care package as they're calling it. Bring up SI B00 13 14 to them.

Mein Auto: 2011 X5 M
I called the local Austin BMW dealership, gave them my vin, was told the injector recall didn't include my X5. I had my injectors replaced at a local BMW Range Rover specialist. I didn't use the recall nomenclature assuming they'd know if my car was included or not. Perhaps I should call them back to double check. The dealer didn't do the work on my injectors, so I figured that ship has already sailed anyway. I love my X5M. But, she's been a little temperamental.

My "instant" mileage usually shows 15.5 mpg. That is for a combination of in-town driving, and highway driving combined. When I'm putting my foot in it, mpg drops to 10-11. If I'm out on the highway at 70-80 mpg climbs to 19-20 mpg.

Thanks guys again for the information. I will have to mention the recall to the dealer when I take it in for service.

ND40oz, I dropped the X5M off this morning as I was having some other work done and mentioned the customer care package 'RECALL'. The SA says that since there are no recalls listed in the vehicle lookup my 2010 X5M does not qualify and that the 'recall' applies depending on VIN #. Does that make sense? I thought that this was an issue with all BMW's with that engine.

Mein Auto: 2011 X5 M
That is essentially what I was told when I queried the Austin BMW Dealership on the recall. They asked for my VIN, and I was told that there are no recalls that include my 2011 X5 M's VIN. As I posted back in October, my X5 injector problem started with a steady check engine light. Within a day, the engine would start (from cold overnight condition) but only in the "limp home" mode. The limp home mode reverted to normal operation once the engine came up to 205 degrees on the water temp. I did not know it was three of the eight injectors that were causing the limp home mode. Those three injectors were leaking raw fuel into three of the eight cylinders while parked overnight. I learned a day or two later why the engine was not happy, and replaced all eight Gen 1 injectors with the Gen 3 version, new plugs, oil and filter change. All of this occurred with 43K miles on the X5. I was both surprised and disappointed by this epic failure of the direct injectors. I had hoped for a little help via BMW's 50 K mile warranty, but found that my warranty expired in May 2014 based on the date the X5 was put into service.

Immediately following the injector replacement, The X5 told me it needed rear brakes. I was surprised once again that I needed to replace the rotors, pads and wear sensors on both rear wheels. At 43K miles, I was surprised again. The rotors were in excellent condition (no scoring or scratches). The cost to replace the rear rotors, pads and wear sensors came to $900. Surprisingly, the front brakes were in excellent condition at the time? In my experience with every other vehicle I have owned, the front brakes usually need replacement before the rears. I have all of the maintenance records since the X5 was delivered, and there are no records saying the front brakes have ever been replaced.

Now the engine runs perfectly, the brakes work perfectly, and I am getting an "excessive voltage use while engine stopped" message on start up each day. So far, the engine starts with no difficulty, but I am told by my BMW mechanic that the battery will need replacement soon. That will cost $400 or so when the time comes. It was explained to me that I won't be able to swap out the battery myself, since I don't have the necessary "bypass" machine to preserve the ECU's programming during the battery swap. I'll have to take it into the repair shop for the battery swap or else the ECU will need to be re-programmed.

I turn everything off when I shut the engine down. I have no idea what components may be drawing electricity when the vehicle is parked with engine off. I've tried leaving the X5 alarm off overnight, but it doesn't seem to matter. The onboard warning tells me to power down all electrical consumers, but I have no idea what else I can shut off other than the alarm system. I plan to replace the battery soon, and I hope the daily caution message will go away.

I have now put about 5K miles on the new injectors, and I am happy to report they are working perfectly. I have noticed that the rear end of my white X5 M gets coated in oily soot in between washes. This soot is tough to remove, so I am wondering if this happens while the engine is cold and still coming up to operating temperature? Once the engine is up to operating temp, I don't see "the cloud" behind me while accelerating. It's as though the engine is running very rich while below 210 degrees. I was wondering if anyone else was experiencing this oily soot accumulation on the rear hatch area? I try to use only light throttle until the temp comes up to 200 degrees or so. This technique seems to slow down the soot accumulation, but not entirely.

That sounds like a lot of work for a car with low mileage. I guess that is what you get with a BMW.

Just curious, how much did it cost to get all eight injectors replaced? I got a quote from my local BMW dealership for just over $4000.

I've only got 1000 miles on the car since i bought it used... I have developed a love/hate relationship with this beast. Low MPG's were expected when I bought it but I've been driving like a 'grandma' and still only getting 11 mpg.

Cost to replace all 8 injectors, oil and filter change, 8 new spark plugs at a local BMW / Range Rover specialist shop (not at Dealer) was $3700.

Rear brake job $900

All of this work needed within 400 miles of buying the 2011 X5 M from the second owner. I have all the maintenance records on the car, purchased new locally.

These cars are quite complex, and can be expensive when they break. The original owner installed a chip, and lowered the car several inches.

I have enjoyed my ownership, but it has been a challenge. These high output twin turbo v8s get reasonable mileage when you consider the high horsepower and torque they are capable of. All wheel drive helps keep all of the available power under control and the car is content to be driven at normal speeds. Things start happening quite quickly if one pushes the skinny pedal a little too aggressively. It's a well thought out vehicle, but it's never going to be a fuel mileage champ. I'm still getting acclimated to driving such a capable ride. Good luck with your X5 M. I plan to keep mine for a long time.

This post makes me worried now because I'm at 45000 miles in my 2010. The spark plugs need to be replaced every third oil change or 45000 miles according to the owners manual, but I wasn't aware of the fuel injector issues.

I replaced the plugs in my 2011 X5 M at the same time the injectors were replaced. Three of the plugs were fouled because of the injector failure. I was not aware of the recommendation to replace the plugs every three oil changes (every 15k miles). The plugs cost about $30 each, so that's an additional maintenance expense and chore I can now look forward to. Great! I love driving the X5, but she's proving to be a bit of a challenge to keep all of her systems operating properly. Lately, I get warning messages each morning that there is excessive battery drain while the car and it's systems are switched off. I guess I'll have to replace the battery next ($425 for battery and labor). Good luck with your 2010.

Thanks! I'm in the same situation as you are. I bought mine used so I don't know it's history. I went to Ferman BMW to request a 27 point inspection after I purchased it, and the service advisor said the water pumps (plural - it has two pumps!) were replaced with less than 24000 miles when it was under warranty. Unfortunately, he would not provide me with a print out of its service history. He said it was confidential. When I asked him about routine maintenance items, like wiper blades, transmission fluid flushes, etc. he told me there are no recommended intervals for them. The only reason I know about replacing the spark plugs is because it's in the supplementary owners manual. I later discovered certain dealerships have an M certification where their mechanics are specifically trained to work on M models. I'm going to take mine to Reeves to get a second opinion from them as they are M Certified. I recently ordered a set of OEM spark plugs for it and plan to install them soon. I will post a How-To if one doesn't already exist so others can do it themselves. My coworker designed the BMW X5/X6 during his time at BMW and he said replacing the spark plugs is something backyard mechanics like me can do in an afternoon.

Anyone ever heard of the "customer care package"?
It is not a recall or service bulletin, but a courtesy service to replace injectors, timing chains, plugs, packs, etc... about an $11k service for existing owners to correct the injector and related issues free of charge. I know its available to N63, but not sure if applicable to S63.
:/

That customer care package only applies to the N63 engine, not the S63 engine in the X5M. Hoping in the future BMW extends the package to the S63 because I believe they share a lot of the same parts, but nothing yet.
