BMW DIY Video - Why You Should Change Your BMW or MINI Spark Plugs Before Recommended Interval

Maintenance intervals for today’s BMWs and MINIs rely heavily on what BMW calls CBS (Condition Based Service). The CBS program computes service and replacement intervals for various vehicle systems based on inputs from sensors, vehicle mileage and vehicle use. The CBS monitors various vehicle systems for service, such as; engine oil, brake pads, brake fluid, cabin micro-filters, spark plugs and overall vehicle inspection and service intervals. While the built-in service reminders (regardless of which version is in use on your BMW or MINI) can help assure that the vehicle receives at least some level of maintenance, these reminder intervals are typically longer than desired for an optimum vehicle life cycle. The reminders really should be viewed as the absolute minimum service intervals and certainly not the intervals for maximum systems longevity.

One good example of extended service intervals is the engine spark plugs. Current models run with spark plug replacement intervals at about 100,000 miles. The spark plugs actually wear as a part of their function in producing a spark. When the spark is produced, a small amount of metal from the electrode is removed (or, worn away). Over the millions of sparks produced in just 30,000 miles of driving, the electrodes will start to show physical wear. As the electrodes wear they become rounded and the gap increases. The increased gap is an obvious issue in reducing spark energy and consistency, but the rounded electrodes actually have more of a degrading effect on the spark than the slight gap increase. Add the two together and we start to see a general degradation in engine efficiency. We may even start to experience noticeable misfires.

While the spark plugs used today, as well as improved engine management, do allow longer service intervals than the BMW recommended 30,000 miles from the ‘80s, we have consistently found that the 100,000 mile recommendation is well past the optimum spark plug life cycle. While the plugs may still be operating acceptably, in general, they may be experiencing random misfires and reduced spark energy. This is due to the normal wear of the electrodes. We may see this degradation as a noticeable miss in the engine or generation of an engine management fault code (CHECK ENGINE or Service Engine Soon warning light).

So what can you, the BMW or MINI owner, do about this? Replace your BMW’s or MINI’s spark plugs at a shorter interval. With experience, we recommend replacement between 30,000 and 40,000 miles to ensure maximum fuel efficiency (fuel mileage) and engine performance. Check out the samples of spark plugs that we recently pulled from three different vehicles. Coincidentally, each of these sets of plugs had between 30,000 and 35,000 miles on them. All were exhibiting noticeable engine misfires. One of the two later vehicles also displayed individual cylinder misfire fault codes. Note that all of the plugs were burning well. In other words, no heavy carbon, oil or fuel additive build-up that would have caused the misfires. The plugs are just simply worn. New spark plugs cured the misfires and improved engine response on all three.

Check out the old vs. new spark plugs for these three vehicles, noting the fairly clean burning, but worn electrodes:

1995 M3, 145,000 miles:
Occasional misfires (bucking) under acceleration. No fault codes. Spark plugs had between 30,000 and 35,000 miles of use.

2012 MINI Cooper, 32,000 miles:
Quite apparent engine misfire and backfire noise through exhaust. Cylinder #4 misfire fault code. Spark plugs had 32,000 miles of use (original plugs).

2007 335i, 90,000 miles:
misfires under acceleration. No fault codes. Spark plugs had 31,000 miles of use (Walnut de-carbon blast performed 8,000 miles before).

The New BMW Mini Cooper 2021 - 2022 || New operating system & digital services

Perfectly networked, always online, seamlessly integrated and always ready for typical MINI driving pleasure. This is how urban premium mobility presents itself in the digital age. Alongside the fresh, strikingly purist design and new equipment features, the extensively enhanced operating system with its additional digital services is a major highlight of the new editions of the MINI 3-door, MINI 5-door and MINI Convertible. Now more than ever, the unmistakable MINI feeling can be seamlessly integrated into the digital lifestyle.

The refined premium ambience in the interior of the MINI 3-door, MINI 5-door and MIN Convertible also includes a redesigned centre instrument. An 8.8-inch touch display in black panel design is now standard. The control units for the audio system and the touch-sensitive favourite buttons are integrated flush into the high-quality Piano Black high-gloss surface. The light signal of the LED decor ring surrounding the centre instrument can correspond to the operation of the air conditioning, among other things. If the heat output is increased, the display moves to the red area; if the desired temperature is reduced, the display again moves to the blue area. In conjunction with the Ambient Light option, the LED decor ring features a distinctive laser engraving.

The current advances in the field of digitalisation are also symbolised by the multifunctional instrument display on the steering column, which is part of the Connected Media option. The 5.0-inch colour display, which also uses black panel technology, shows all relevant driving information. In the MINI Cooper SE (fuel consumption combined: 0.0 l/100 km; electricity consumption combined: 17.6 - 15.2 kWh/100 km according to WLTP, 16.1 - 14.9 kWh/100 km according to NEDC, CO2 emissions combined: 0 g/km) it also serves as a display for the charging status while connected to the power supply.

The latest generation of the operating system in the MINI 3-door, MINI 5-door and MINI Convertible ensures that driving pleasure is accompanied by a completely new user experience. Menu selection on the touch display of the centre instrument becomes even more intuitive with a significantly modernised layout. For the first time, Live Widgets are available for this purpose, which can be selected by a swipe. The desired function is then enlarged in the centre of the display. This means that operation in the MINI is even more closely aligned with the user behaviour familiar from smartphones and other digital devices. The content of the Live Widgets and the order in which they are arranged can be configured individually.

The standard configuration shows one widget each for the menu items Media, Communication, Navigation, Vehicle Settings, the MINI Connected Apps and Messages. Depending on the function, the current status - for example, the route currently being taken on the navigation map or the last audio programme selected - is always displayed on the corresponding graphic.
