Maintenance interval
Where do I find in the manual what items need to be changed or replaced on the car at different intervals. You know some manufacturers have a list of items that needs to be changed/repaired at 20k, 40k, 60k, 100k miles etc? I just want to plan ahead if I don't buy the extended maintenance coverage.
Such as brake pads and brake discs? |

BMW are Wise Guys - they don`t supply maintenance scheme - they have built that into the electronics, saying that "electronics" will monitor behaviour and adjust intervalls accordingly - halfway true - halfway Bull
Anyway - electronics will tell you when to do what! |

Peter, main reason for changing brake fluid is that, in time, there will be water in the fluid, and when going down an extreme downhill run in Austria - where "all" manufacturers are testing- there might be a brake failure because of boiling water= steam. Everybody else - not going that run - is far from boiling brake fluid.
BMW requires that brake fluid should be exchanged every second year - or so. They give the reason that Bosch requires this. Bosch did not require this for the manufacturer I worked for. In my eyes this is Bull. Especially since it is possibel to measure content of water in the fluid - and change if needed. The "secret" service intervalls is one of few things I don`t like with my BMW. |

So what? Not relevant to BMW.

How do I know all this and keep challenging all the stuff that ill informed people post about how bad BMW and other manufacturers are when it comes to servicing. Well, just a small piece of information should suffice. For 5 years I headed the Royal Air Force Spectrometric Oil Analysis Program in the MOD DQATS Laboratory in Woolwich in London. Known as the RAF SOAP Laboratory. We analysed ALL oil, fuel and hydraulic samples that we taken from ALL fixed wing and rotary wing aircraft every 50 flying hours. We also did the same for vehicles and Battle Tanks. From the data obtained from burning these samples on Spectrometers we built up the largest database in the world and we used this data to create algorithms for servicing. The information was used to create "on condition" monitoring for components. This basic data is still used and is "tweaked" as fluids are improved over time. I could go on, but there is no point whatsoever. Every time someone posts that BMW are rubbish at doing this or that, then I say go and show them your scientific analysis to back up your case and challenge theirs. Thanks |

Are you talking about that problem, or do you have some other problem in mind. My car being the X3 xDrive30d M Sport has an engine oil change interval of 18000 miles. When I went to have the servicing carried out in October, they advised me that the brake fluid change had been moved from 2 years to 3 years. Not everything makes sense to me. |

Weird! Must be a litigation thing or something to do with wear that they started to see in higher mileage models. |

BMW is great compared to Ford... When I bought my last Ford five years ago, the sales guy told me that the car would tell how often it would be serviced. I read the manual and it said the same thing. So... I followed the recommendation. However, the service department, when I brought the car in said, "you haven't serviced in 12,000km that's a problem" I said, no I followed the manual. There response was "would you trust a computer to check your service interval?" It was insanity.
Anyway, I love my Ford but the service department are morons. They don't even follow their own service recommendations. I'm happy to be moving to BMW where they will actually call me when there is an issue and the service interval seems much longer than the Ford. If they wanted to gauge you on service intervals they would make you come in every 8,000km like my Ford dealer does. |

Peter, I dont want to fight you - I believe you make valuable contributions to this forum, and hence this is my last input in this matter. However, even the sun has.....
I have worked with and monitored ABS/ESP development for many years. I can`t, for various reasons go into all details, but you almost admitted yourself that the 2 year mandatory fluid change is Bull - you mentioned that BMW recently went from 2 to 3 years of brakefluid change. I have strong indications that it would be safe to go to 4-5 years, providing water content is measured -yes it is fairly inexpensive to measure water in the fluid - many non-brand workshops in Sweden do this. The Brand workshops - of course - prefer to change fluid. Water will gather, primarily, in the reservoir and brake cylinders. According to a source, the German authorities measure water in the reservoir as part of the yearly inspection. ABS are designed with a certain amount of being foolproof i.e. if system does not work - brakes still function, but no ABS function. A set of hard brakings will get you warm/hot discs, but cylinders - almost - unaffected. All in all, this is part of the universal question:shall the owner/independent workshop do any change to instructions or components from the manufacturers. Having worked for many years for a manufacturer, I have a tendency to say no. There is however one sore point: I have for many years realised that the customers are being taken for a ride with unnecessary brakefluid changes. I have for most times been driving test- and company cars, but have never changed brake fluid on my own cars. That is out of interest, and not something I would recommend. I have three years of free sevice on my X4 - hopefully that includes change of fluid - then I will wait 5 years - if I keep it that long. Note: my 9000 Turbo passed the Swedish yearly inspection today - I have had it for 7 years - it is 17 years old - no change of brake fluid during my time. ABS works. |
