If you feel that the performance of your engine is not what it used to be, it could be the catalytic converter. The issues with faulty electronic windows are not the only electronic fault reported by BMW owners. Most people are familiar with the fuse box in their home, but not everyone knows that cars have their own fuse boxes too — and that is definitely the first place to look if the electronics in your BMW have kicked the bucket.

However, more serious flaws have been reported with the electronics systems in BMW cars which led to the recall of more than , vehicles in the UK in , after the fault was linked to the death of one BMW driver in Hampshire, England.

Owners of some of the most popular BMW models have reported issues with the high-pressure fuel pump, which can cause poor acceleration, engine stuttering at high speed, or even a failure of the engine to turn over at all. All engines have two fuel pumps, the low-pressure pump which takes gas out of the tank, and the high-pressure pump which pushes the gasoline into the combustion chamber.

If the high-pressure fuel pump in your BMW is performing below par, the only solution is to fix it, which is not a cheap repair if the car is out of warranty. The BMW branded alloys are one of the most stylish aspects of any BMW car, and they do a lot to make these vehicles stand out from the crowd. Unfortunately, some owners have found that these great-looking alloys are more style than substance, as they have started to corrode after a relatively short amount of time.

Aside from not looking great, this corrosion can also have an impact on the performance of the car, as corroded alloys can affect both the wheels and even the tires. You can shell out on a new set of BMW alloys, but lots of owners go for a non-branded but more reliable set to prevent further problems.

Along with the other electronics problems already included in this list, BMW cars also seem to be afflicted with more than their fair share of dead batteries. Luckily, it is pretty easy to jump-start a BMW from another car — it is just annoying if you find that you are having to jump-start your car once every few weeks.

Automatic headlights are a relatively new automotive innovation, taking the human element out of deciding when it is dark enough to require headlights. The problem with some BMW automatic headlights is that they stay on, even when they are not required, running down the battery and exacerbating other electronics problems in the car. Owners of Audi vehicles have to put up with more than their fair share of annoying problems too. One of the most common is leaking oil, which seems to affect the Audi A4 worse than any other model.

These leaks can be caused by issues with one of several engine parts — the camshaft seals, valve cover gaskets, and the front and rear crankshaft seals. Electronics also cause a few issues with Audi vehicles — and given how many of the important parts of modern cars rely on electronics, these can easily end up being serious and expensive faults.

Be sure to flush the unit from both ends. Another way to clean the catalytic converter is to soak it overnight in a combination of hot water and degreaser or laundry detergent. This process takes longer but is necessary to dissolve the deposits clogging up your catalytic converter.

After washing or soaking, be sure to dry the catalytic converter completely before reinstalling. Sometimes, the catalytic converter absolutely needs to be replaced like if it's broken internally or melted down. If you have to replace your catalytic converter, make sure it lasts as long as possible with these tips.
