Signs Your BMW Gearbox Is Failing (Before It Leaves You Stranded)

They build slowly, a slight hesitation here, a small shudder there, until one day the car does something alarming enough that you cannot ignore it. The BMW owners who catch it early spend a few hundred pounds on a fluid service. The ones who miss the signs spend considerably more. This article uses plain language. No technical jargon. Just the things you will notice from the driver's seat, and what they mean. First – What Gearbox Do Most BMWs Have? Most modern BMWs come with an 8-speed automatic gearbox made by a German company called ZF. It is not a BMW gearbox. ZF makes it. BMW fits it. It is actually one of the better automatic gearboxes available, and it will last a very long time if the oil is changed regularly. If it is never serviced, it starts to misbehave somewhere between 60,000 and 100,000 miles. The most important thing most BMW owners...

Why Do BMW Xenon Headlights Stop Working? (And How to Fix Them)

-

Image: BMW X6 Series Xenon Headlight for sale at MT Auto Parts for £284.99 One headlight goes out. You replace the bulb, and it still does not work. Or one side flickers on startup and then cuts off. Or both headlights are working, but one is noticeably dimmer than the other and has a slightly different colour. These are the typical presentations of BMW xenon headlight faults, and in most cases the bulb is not the problem. BMW xenon headlights are a three-component system. Understanding which of the three has failed saves money and avoids replacing parts that were working fine. How BMW Xenon Headlights Work Unlike a halogen bulb that simply glows when current passes through a filament, a xenon bulb creates an arc between two electrodes inside a gas-filled capsule. To start that arc, the system generates a pulse of around 25,000 volts at ignition, then maintains the arc at a lower operating voltage once lit. Three components make this happen. The ballast converts the car's 12-volt ...

Fitting a Dash Cam to Your BMW: What It Costs and What to Know Before You Start

-

  Image: BMW OEM Rear View Camera for Sale at MT Auto Parts for £94.89 A dashcam on a BMW is one of those purchases that feels unnecessary until the moment you actually need it. In the UK, hit-and-run incidents, fraudulent insurance claims, and car park damage are common enough that a dashcam pays for itself within a few years for most drivers. Installing one on a BMW takes a bit more thought than on a standard car, mostly because BMW owners tend to care about how it looks inside the cabin. Plug-In vs Hardwired — Which to Choose Plug-in means the dashcam runs from the 12V cigarette socket with a cable running visibly across the dash. It works, it is simple, and it can be moved between cars easily. The downside is the cable and the loss of the socket. Most BMW owners who keep a car for more than a few months end up wishing they had gone hardwired. Hardwired means the camera is connected directly to a fused spur from the fuse box, typically in the A-pillar or behind the mirror, with...

How to Tell If Your BMW's Driveshaft Is on Its Way Out

-

A clunking sound under load that appears when you accelerate hard. Each of these symptoms can mean several things, but on a BMW that has covered meaningful mileage, the driveshaft is one of the first places an experienced technician will look. BMW driveshaft problems on newer BMW models are not common in the way that, say, timing chain issues on certain engines are. But they do occur, particularly on higher-mileage cars where the CV boots have been neglected, or on xDrive models where the additional front driveshafts carry more stress than a rear-drive equivalent. Knowing what to listen for can save you from a more expensive repair down the line. What the Driveshaft Does in the BMW The driveshaft transfers power from the gearbox and differential to the driven wheels. On a rear-wheel drive BMW, there...
