BMW Service Book

This article is for you who own a BMW or are considering buying one. The service itself is rarely what annoys. It's the documentation: who has registered what, where it is and whether you can find it on the day the warranty or the sale price depends on it.

How often does a BMW need to be serviced?

A BMW follows the manufacturer's own instructions, and on newer models, the interval is not fixed. The car keeps an eye on how hard it is being used and reports when an inspection is approaching. In practice, it is typically between 20,000 and 30,000 km, depending on the model, engine and driving. If you drive a few kilometers a year, it will instead be an annual interval, usually every year or two.

You can choose your workshop, so you decide where your BMW is serviced. Pay attention to which spare parts and oil are used: with some manufacturers, the warranty is void if original or OE-approved parts have not been used.

How service is registered today

Previously, the registration was a stamp in the paper service book. BMW has moved away from this, and with good reason: a service book that was at home or lost left gaps in the history that could not be closed afterwards. You still get an invoice after each inspection, but few people keep them for twenty years, and a pile of invoices rarely provides an overview.

Today, the workshops register online, and this applies to both BMW's own workshops and the independent workshops.

BMW's own digital service book

BMW has been an early adopter of two tracks. In 2002, Condition Based Service introduced the then new 7 Series, and it is the model that still applies: the car assesses its own need for maintenance instead of just following a fixed interval. In 2011, the new 1 Series was followed by the Aftersales Online System, and thus began the transition from paper to digital recording of the work done.

The information is stored centrally at BMW and put back in the car, so that the history of newer models can be read in the car itself. It works as long as you own the car and stay in BMW's own system. An independent workshop can register service, but cannot look up the complete history afterwards. This means that the mechanic who will assess your car cannot necessarily see what has been done on it before. And it means that the history lives somewhere that you as an owner find difficult to get out and pass on.

Is it a requirement to use BMW's own service book?

No. Many garages and car owners have got this impression, but it is not BMW's own digital service book that is the requirement.

The requirement is the documentation. If you end up in a warranty case, you must be able to show that the service intervals have been complied with and that the work has been carried out according to the regulations with approved parts and oil. Where that documentation is located is not the decisive factor. That you can find it is.

Why your BMW's service history matters

A warranty case is the obvious occasion, but not the only one. If the car is to be sold, a coherent history is what moves the price, because it gives the buyer the assurance that the car is maintained. The odometer reading is stored with each registration, so a history with dates and mileage is also the best protection against tampering with the odometer.

History also has a practical value in the workshop. If you know what has been changed and when, troubleshooting becomes shorter and the right parts can be found the first time.

If the history is scattered or has gaps

This is common, especially on older cars and on cars that have changed owners or workshops several times. Part of the history may be in BMW's own system, some at an independent workshop, and some may be lost along with a paper service book.

In the Digital Service Book, your BMW can be searched for on the number plate. The lookup covers registrations from the manufacturers' own service books, BMWs included, and from the workshops that are connected. If there is service that is not included, previous inspections from a paper service book or old invoices can be entered, so that the history is collected on the car instead of being in three systems and a folder.

When your BMW changes hands

Add the car to your own account while you have it. Your own car's history is free for you as the owner, and the service that is carried out in the future is collected on the car. Then you will have the documentation on the day the car is to be moved on. If you are considering a used BMW that you do not own yet, you can buy a service certificate on the number plate before the purchase.
