BMW 5-Series Maintenance and Repair

    I came across this in the Feb 2010 issue of Automobile which is relevant to our discussion of tire speed ratings.

    You may never achieve high speeds like this at home but all new car and truck tires sold in the United States have speed ratings on them. A tire's ability to deal with high speeds doesn't necessarily increase it's handling and braking but generally there is a correlation--so if you're looking for a higher performance tire, look for a higher speed rating.

    (Emphasis added)

    2000 BMW 528i, 2001 BMW 330CiC

  • The 2009/10 E60 with N54 is an amazing vehicle - when it runs. In the past 5 years, I've purchased a 645, 750, and two 5s, all brand new. Never a single issue with any, until the '09 535i (N54B30).

    What a nightmare, and BMW NA refuses to even help. In 8 months (since I took delivery), the fuel pump failed (HPFP), water pump failed, fuel control system failed, each time a tow and an extended period out of service. Now the charging system won't charge the battery - 2 more tow trucks in the past 3 weeks. After a looong drive, it will hold the charge for about 4-days, then it's dead again. "Click". BMW Emergency Road Service is in my speed dial!

    It's been "out of service" for 24 days (in 9-months) and BMW NA said "that's normal". Local dealer, where I purchased 4 NEW CARS, recommended I change my driving habits to accommodate the weak charging system, aka take longer trips. Hmmm, change my life because the car won't charge.....

    My driving habits/trip length is identical in the 528i, which has never had a single problem.

    Now I'm hearing about all kinds of buy-backs, lemon law-based arbitration cases, etc., due to these known problems with the N54. Yet they deny there's anything wrong with my unreliable lemon.

    So how come BMW won't take this dog back (zero sum) and let me spend even more money on a nice new X-6??
  • I have a 2000 528i manual tranny which I have always had serviced at the dealer until they told me they wanted $300 to replace the winshield washer motor and a reputable indy shop did it for $80! So yesterday I took it in for an oil change- this shop used Pentosynth 5w-40 which looks like it is ok (is it??)- but the main thing that got my attention is I am supposed to get it changed again in 5,000 miles- well I have never done that- I only put about 9,000 miles/yr on the car- not enough to put all the green lights out on the oil service indicator, so I have been having it changed once a year at the dealer. If I have to get it changed more than this because of this Pentosynth oil then it would be cheaper for me to go back to the dealer. Any advice would be appreciated.
  • Have you had a lawyer send a written notification to BMW NA? Depends what state you live in, but after so many attempts to fix an issue, the lemon law applies. Also if the car is out of service more than 30 days. I think you have 1 yr/12K miles for these events to occur.

    My dealer has stated that there are issues with the HPFP on the twin turbos - 335, 535, etc.. I've also been asked if my battery has gone dead. I've had fuel injectors, HPFP, cylinders, etc. replaced. After the last fix, had major acceleration lag, especially off the line. Dealer couldn't find anything wrong, kept it for 8 days, but magically it is fine off the line, and I feel a slight lag as it shifts through the gears. it is not safe to drive as it has broken down like yours. Sometimes I travel into very cold areas with no cell service, so cannot take a chance on breaking down, and having to walk at least 10 miles in -28 degree weather.

    My car is under consideration for the Lemon Law. Should get a response this month. If no from BMW NA, next step is BBB for arbitration, which is only binding to the dealer. You can then move onto a lawsuit. In the end you will recoup lawyer's fees, rental fees, etc. My suggestion is to have an attorney send the written notification to BMW NA - see section on this in your warranty manual - stating your intent to go the distance.

    You should be good with an annual oil change; I've had the oil analyzed in my wife's X3 2.5 at almost every oil change and 9000 miles is a perfectly acceptable interval for any decent synthetic.

    Thanks for the reply Sportcourtguy. How did you get them to pay?

    Our first experience ended up with our vehicle being down 6 days and with no repair but the dealer charged us $300 to dry the car out and sugested a sunroof repair that would be over $1k but that they were not confident that it would solve the problem. Our service advisor (who is now no longer employed) told us that they cleaned out all of the drains and to let them know if it happens again. So in other words they did not find the problem.

    It just rained this past Saturday and the car was again full of water on the passenger side. While it was still raining we took the car back to the dealer and the new service advisor was "shocked" to see the amount of water and put his "top" technician on it. Yesterday the service advisor calls and asks me to come in because they found the problem. It turns out that under the hood on the passenger side they said that there were a bunch of leaves cloging the cabin filter drain and that water was overflowing from this and donw towards the heater box. From there it was landing on a tray with a chanel that enters the passenger side just under the dash which the tech explained to me is to allow air in to cool the ECU. This channel is filling up with water which then is pouring into the car! Now I am no engineer but this does not sound like a very good design. Also in looking at this water is going down into this area and there is nothing we can do to prevent this. Long story short they want over $2k now to dry out the car, replace the sub woofer that is completely under water along with everything else. They are unsure if any sensors are damaged so it may be more. We are not happy with this needless to say. Also there is nothing being done to address the source of the water intrusion. They ae telling us that they will take responsibility for the repair.....what repair?
  • I realize the posting above was almost three years ago, but my 2001 530i exhibits the same symptoms of the the Nikasil problem for M60 engines.
    Was the M54B30 engine also a Nikasil engine?

    The I6 engines of the E39 line of cars did not use a lined cylinder as did the older V8 engines.

    Nope. What kind of miles are on your engine?


  • on a 2000, 540i, the car smokes in the morning when first starts, any idea of the cause and repair. Thanks
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    If it smokes for a bit on start up and then goes away, chances are this might be valve stem seals. Also if your car has an "oil separator" (a fancy PCV valve system), this can cause oil burning since oil from the defective part can seep into the intake manifold.


  • I've recently purchased a pre-owned 2008 535i. I have 23K miles and the car seems to delay and "jump" forward from a stopped position from time to time. In addition, when I've started the car the last couple of days, it cranks longer than typical before it starts. I thought the "lurching" may have been transmission related but now that I am researching, I understand it may be the High Pressure Pump on which some owners are commenting. Has anyone else experienced this problem?
  • 125K. The car (2001 530i) lurched to a stop a few months ago. I had just filled it with gasoline; 30 mpg on a 70% highway/30% town driving mix on the previous tank which had been the norm. Towed the car to a mechanic. The mechanic did a compresssion test. "0" compresssion in all cylinders. He took off the head. Tops of the cylinder walls were seriously "etched". A sample of the gasoline had some water in it, and a funny black/multi-colored substance floating on top. I had the fuel analyzed. They simply said it had water in it, and was slightly weathered. Apparently the substance on top was not analyzed. The engine is toast.

    I seriously doubt that water injected into the engine via the fuel injectors was enough to be able to cause that kind of damage, that said, I've heard of some pretty serious damage being caused to gasoline engines when diesel fuel is inadvertantly added to the gas tank. I'm wondering if some diesel was incorrectly added to the tanks of the gas station where you'd just filled up.

    I think I'd be talking to the station directly or through legal representation if I was in your shoes.
  • The delay and jump symptom sounds like an acceleration lag off the line. Lurching could be a fuel injector misfiring. With the misfiring, I was experiencing very rough idling and above 50 mph the car almost felt like it was bucking, which was the misfiring. The long cranking is a symptom of the HPFP. I would take your car into a BMW dealer for evaluation of the software (acceleration lag - new update was out in Jan 2009 per a class action resolution), HPFP (long cranking), and fuel injectors (lurching). Make sure you tell them all the symptoms so they look at everything. They don't really have resolution to the issues except replacing parts with no guarantee from what I am told by my service manager. There hasn't been a recall.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 44,403
    Can't say without seeing a photo of the damage, but it could be related to severe detonation----very odd diagnosis, that ALL cylinders would be absolutely "0". This suggests, if true, a total catastrophe of some kind that should not be hard to identify. Your report is very puzzling to me. Are you quite sure your timing chain didn't snap, or that the car did not severely and rapidly overheat?

    IN any event, I don't see this related to the gasoline issue. Now, if someone had put gasoline in a diesel engine, well....maybe...but diesel or water just makes an engine stop from lack of combustion.

    I'd like to hear a *much* better explanation of how we lost compression in all cylinders simultaneously. Until we have that, I don't think you have a case here.


  • shiposhipo Posts: 9,152
    I've seen two gasoline engines that were violently destroyed due to diesel fuel being used. From the looks of things, detonation was occuring at the extreme and the valves and piston domes took the brunt of the damage. That said, it was summer time and both of these engines were carbureted; I'm not at all sure the injectors of a fuel injected engine (operating in the winter time no less) would be able to feed enough diesel fuel into the induction system to cause the detonation I saw on those engines.

    Best regards,

    I can't even imagine someone attempting to drive a gasoline car that was struggling to run on diesel fuel. There would be so much smoke, noise, sputtering etc, it would seem rather reckless to push an engine to such extremes. I can't imagine how the car could go 5 miles on diesel fuel.

    Of course, we are talking about *pure* diesel fuel, not a cupful. A cupful in a tank of gas wouldn't hurt anything IMO. Even a cupful of water wouldn't do much more than cause sputtering (maybe) and a clogged up fuel filter perhaps.

    Sudden loss of compression on all 6 cylinders is a pretty amazing occurrence. I was thinking there would be an obvious answer to why this happened.
