Service intervals
What do people think of the service intervals? 18,000 miles seems a lot between services. I have the service plan so it's not in my interest to service the car (just done 10,000 miles) now but my friend who I went to school with is a mechanic and he states that 18,000 miles between services makes him nervous and recommends every 12,000 miles max. We own our car and I intend to keep it for 10 years so I want to know it's had the best care in terms of oil and maintenance.

20 years Ok that may have been the case - but with CBM - (condition based maintenance) and tech oils is is clear that it can easily be 18k+.
Not heard of a single engine failure so accept the service details for what they are.

I share your concern - I also plan to keep my vehicle for about 10 years.
I have two cars, and hence low mileage - about 10.000 km/year. I have designed a serviceplan based on experience from SAAB: -engine oil once a year - a bit over the top, but feels good. -oilfilter every second year -sparkplugs - check/adjust every year -engine airfilter - change every forth year- no heavy industries nearby -cabin airfilter - " " -brakefluid - change every fourth year -AUTO- change oil every fourth year I do not plan to change coolant, transmission oil nor servofluid. I am open for improvements based on experience from BMW. I will NOT service at BMW dealer after free maintanence is out. (3 years) |

Lifetime to BMW means about 100,000 miles (which is the maximum coverage of an extended warranty). |

Are you excluding N47 timing chain issues from your comment "not a single engine failure" ?

Not seen any evidence that the timing chain failure is linked to frequency of oil change.
I have seen a lot of evidence abut CBM - it was Ford who looked at it first and then dropped it - because the dealers would lose a lot from reduced servicing revenues. It was picked up by others and has been widely adopted. In many many cases a lot of servicing was found to be a waste of time and money.

Polo: because I see no reason why - based on experience. Automatic gearbox is a tricky design - hence oilchange, while I have not changed coolant, oil in manual gearbox nor fluid in servo on my 17 year old SAAB 9000 - 275.000 km.
Do you have different experience? I am open for suggestion. "lifetime for BMW is 100.000 miles" - 9000 was designed for 15 years and 225.000 km - mine is on overtime. |

Both of my 5 series autos were sold with excess of 120,000 miles and the new owners ran them for many many years ( i bumped into one 3 years after selling the car to him and the car was at 170,000 miles)
I can't see lifetime meaning 100, 000 |

Then I should change oil in gearbox after about 8 years?
With transmission I meant all transmission components but automatic gearbox. I have seen nothing about sensitivity for the clutches, that makes up the performance of the AWD. Anybody? I found an instruction on how to remove sparkplugs - that put me off - I might wait 4 years, if engine running OK. I will, of course, also see what BMW will do during the 3 years of free maintenance. |

My previous BMW was a 1999 328i E46 with the M52TU 2.8l engine.
I followed the OBC as far as oil change interval and often went 15k to 18k miles between oil changes. Also never touched the transmission fluid. When I sold it at 175k miles, engine and transmission was still running as smooth as day 1 with 6 miles on it. The mechanic I sold it to did a compression test, and took off the oil pan and said he can't believe how clean it was (i.e. no sludge buildup) and no compression leaks. Never had any engine or transmission issues in the time I owned it. I've always followed the MFG recommended OCI on all vehicles and never had any issues even when it states 18k mile OCI. |

I concur with much of your original service plan. However, checking and adjusting spark plugs annually is excessive in my opinion and might even contribute to problems. Your current thinking to check plugs every four years unless there is a problem sounds reasonable. However, I would be more inclined to simply change the plugs at this interval given the time and effort involved to access and remove them.
Modern engines are generally not as prone to foul spark plugs. The spark plugs with platinum or iridium coated electrodes have a long life. Efforts to check or change the gap on such plugs may damage the coating. Repeated manipulation of spark plug wires and other components to access spark plugs may inadvertently cause damage to these components. Last edited by MichiganMike; 05-26-2016 at 07:56 AM.. |

I did mine at around 50k miles, but I believe the specified interval is 60k miles. I ended up buying the spark plugs from BMW. They were not that expensive and they come pre-gapped. http://f30.bimmerpost.com/forums/sho....php?t=1226053 |

Some factors will not supply them as a replacement part now as it's such an issue. A friend of mine was workshop manager for a trucking company for many years. To support the lorries and machines, they had about 70 service vehicles that needed to be dependable. He got fed up with spending so many man-hours on replacing turbos and pulling the heads off vans with snapped cam belts. So he changed the company policy - they changed the oil and filter on every diesel vehicle every 6000 miles, or less if it's getting close when it appeared in the yard. Cam belts got changed every 30,000. (The Escort vans got new belts every 20,000).

If you're tuned and/or don't use top tier gas, then perhaps you might want to try shorter intervals. |
